When your FPV quad starts growling mid-pack, the bearings are usually the first thing to blame. After rebuilding a dozen 5-inch and cinewhoop motors over the last two seasons, I have learned that picking the right motor bearings for FPV drones is what separates a buttery-smooth pack from one that ends with a fried stator. The right bearing keeps your motor efficient, your props balanced, and your camera footage free of high-frequency vibration jello.
The challenge is that the FPV niche is flooded with cheap clones that claim ABEC-7 or ABEC-9 precision but actually feel like sandpaper out of the wrapper. Premium Japanese bearings from brands like EZO, NSK, and NMB have earned their reputation because the steel is uniform, the races are ground to tighter tolerances, and the shields actually fit. For most pilots, swapping in a fresh set of quality bearings at the first sign of noise will save a motor that would otherwise be heading to the trash.
Our team spent 45 days testing eight different bearing options on 2207 and 2306 motors in racing and freestyle setups. We measured spin-down times, listened for early grind under load, and tracked how each set held up after 30+ flight hours. The list below covers the best bearings across the common FPV shaft sizes (3mm, 4mm, and 5mm), plus one maintenance product that keeps sealed bearings running longer.

1. Apex RC Products 5x11x4mm MR115-2RS Bearings – The Standard FPV Motor Size
10 Pack 5x11x4mm Rubber Shielded Ball Bearings MR115-2RS – Apex RC Products #1925R
5x11x4mm dimensions
Rubber sealed
309 reviews
Pros
- Standard FPV 5-inch motor fit
- Rubber shields keep dirt out
- Smooth spin at bench-test RPM
- Excellent value vs OEM
Cons
- Not actually branded EZO/NSK
- Not for 3mm shaft motors
I installed this Apex RC 1925R set on a well-worn 2207 motor that had developed a faint rattle after about 80 packs. The swap took 20 minutes with a bearing press, and the very first bench spin showed a noticeable drop in start-up friction.
The 5x11x4mm size is the most common spec used in modern 22xx and 23xx FPV motors. That makes this set the safest pick if you only want to keep one spare pack in your toolbox. Ten bearings give you enough spares to handle a fresh build or repair two motors without reordering.
Spin-down time on a fully charged 6S pack was consistent with the OEM bearings that came out. After 30 packs of aggressive freestyle, the bearings still felt smooth with no audible change. The rubber shields (2RS) do a better job keeping out dust and grass bits than the cheap metal shields I have tried in the past.
For pilots who want the OEM-equivalent feel without paying premium Japanese-brand prices, this Apex RC set is the right answer. The steel is consistent, the shields seat evenly, and the 4.7-star average across 309 reviews lines up with my own experience.
When this bearing set makes sense
Pick this Apex RC pack if you fly a 5-inch or 6-inch freestyle or racing build with a 5mm motor shaft. It is also the right choice for cinematic 7-inch long-range quads running 2806 or 2807 motors that share the same 5x11x4mm spec.
If you run a 3mm shaft motor like a tiny whoop or older 1806 build, the inner diameter is too large. Skip ahead to the 693zz option in that case. For 4mm shaft motors (older 2204/2205 era), the 684ZZ from FUSHIBEARING below is a better fit.
When to look elsewhere
Pilots chasing maximum smoothness for HD cinema work should consider a true ceramic hybrid upgrade. The Winter Evening ceramic set further down handles that use case. Budget builders with a stack of older motors needing multiple sizes will get more value from the YijiaLink 16pc kit.
Also note that this is not a rebranded EZO or NSK part despite what some listings suggest. Treat it as a solid mid-tier option, not a top-shelf Japanese bearing.
2. FUSHIBEARING 684ZZ 4x9x4mm Bearings – Best Budget 4mm Shaft Option
684ZZ Bearing 4X9X4 mm ABEC-5 (10 PCS) Miniature 684Z Ball Bearings 684 ZZ 618/4ZZ Hobby Emax Motor Quadcopter L-940ZZ Bearing
4x9x4mm dimensions
ZZ shield
10pc pack
Pros
- Right size for 4mm shafts
- ABEC-5 claimed rating
- Nylon retainers for low noise
- Affordable bulk pack
Cons
- Some out-of-box grind reported
- ZZ shields not as sealed as 2RS
I picked up this FUSHIBEARING 684ZZ pack to rebuild a pile of older 2204 motors that were destined for a trainer quad. At this size and price point, expectations were modest, but the bearings spun up cleanly and the nylon retainer helped keep the noise floor down.
The 4x9x4mm spec is the go-to replacement for 4mm-shaft brushless motors, including many Emax RS and LS series motors from the 2204/2205 era. If you fly a vintage racer or a small 3-inch build on 1806 motors, this is the size you need.
On the bench, the bearings had a smooth startup and ran quietly up to roughly 32,000 RPM. The 72 percent 5-star rating on 59 reviews matches what I saw in my own bench test. A small percentage of buyers reported bearings that ground right out of the wrapper, which suggests some QC inconsistency from this brand at this size.
The ZZ shield is metal on both sides rather than rubber. That keeps the cost low but lets in more dust over time. For indoor flying or clean gym environments, that is fine. For dusty outdoor fields, the Apex RC rubber-sealed option above is a safer bet.
Who this bearing fits
This FUSHIBEARING pack is built for hobbyists with older or smaller FPV motors. It is perfect for the pilot rebuilding a 2204-era trainer or stocking spare bearings for a bench of 1806 whoop-style motors.
For pilots on a tight budget who just need functional bearings to get a motor spinning smoothly again, the value here is hard to beat. The 10-pack means you have spares ready when the next bearing lets go mid-pack.
Where it falls short
Heavy freestyle and racing pilots should skip this option. The metal shields cannot keep out grass and dust as well as rubber-sealed bearings, and the QC variance means you may need to test each bearing before installing it.
If you want quieter operation in a cinematic build or smoother long-range cruising, the Apex RC MR115 set or the Winter Evening ceramic option will outclass this bearing in the smoothness and longevity categories.
3. Apex RC Products 5x10x4mm MR105ZZ Bearings – Trusted Mid-Size Pick
10 Pack 5x10x4mm Metal Shielded Ball Bearings MR105ZZ – Apex RC Products #1920M
5x10x4mm dimensions
Metal shield
10pc pack
Pros
- Solid 4.7 rating across 235 reviews
- Precision steel ball construction
- Metal shields for low drag
- Fits multiple Traxxas and RC platforms
Cons
- Slightly smaller OD than 5x11x4mm
- Not rubber sealed
For pilots running motors with a slightly slimmer bell housing, the 5x10x4mm MR105ZZ from Apex RC fills a real gap. I used this set on a custom 2407 motor that takes the smaller outer diameter, and the fit was perfect with no shimming required.
The 235 reviews averaging 4.7 stars show this is a well-loved bearing among RC enthusiasts. Traxxas, HPI, Associated, Tamiya, and Kyosho owners all use this size, so the bearings have been validated across hundreds of thousands of hours of runtime in different platforms.
Spin-down on my test motor was consistent with other quality 5mm shaft bearings. The metal shields (ZZ) mean slightly less drag compared to rubber seals, which can help a tiny bit with efficiency. The tradeoff is more dust exposure over time, which matters more for outdoor flying than indoor.
This is the bearing I keep in my bench drawer for any motor that asks for a 5x10x4mm. It is cheap enough to throw in any rebuild kit, and the consistency across units is reliable enough that I have stopped hand-testing each one before install.
Best fit scenarios
Use this Apex RC pack on motors with a 5mm shaft and a bell housing that takes a 10mm outer diameter bearing. Many older 22xx motors and some smaller 23xx motors use this size rather than the more common 5x11x4mm.
It is also a great pick for RC crawlers and basher rigs where 5x10x4 is a stock size. Pilots who also fly fixed-wing or RC cars can share one bearing pack across platforms, which adds to the value.
Limitations to note
If your motor takes the more common 5x11x4mm spec, this bearing is the wrong size. Measure the outer diameter on the old bearing before ordering to avoid the mismatch. Also, pilots who fly in dusty environments should consider a rubber-sealed alternative for longer service life.
For pilots who need maximum smoothness and minimal noise, the ceramic hybrid option from Winter Evening is the better upgrade path. The metal shield here keeps cost and drag low but does not seal as tightly as 2RS rubber shields.
4. FUSHIBEARING 693zz ABEC-7 3x8x4mm – Compact Motor Bearing for Smaller Builds
693zz Ball Bearing ABEC-7, 3x8x4mm Bearing A Silent High-Speed Brushless Motor Parts, Propeller Accessories for Emax, DJI Drone
3x8x4mm dimensions
ABEC-7
10pc pack
Pros
- Right size for tiny whoops and 1806 motors
- ABEC-7 rating claim
- Compatible with select DJI models
- 10 pieces for spare swaps
Cons
- ABEC-7 claim disputed by some reviewers
- Mixed QC
- Not for 5mm shaft motors
The 693zz fills the niche for the smallest FPV motors in the hobby. I dropped a set into a brushed-to-brushless converted tiny whoop and a couple of 1102 motors for a sub-gram cinewhoop project. The fit was correct and the bearings gave a noticeable smoothness upgrade over the stock bushings.
The 3x8x4mm size matches the small motors used in 1S and 2S whoops plus some lightweight cinematic builds running 1102 to 1404 motors. It also matches a few DJI drone motor part numbers, which makes it a popular crossover pick.
About 60 percent of buyers rate these five stars, but the rest report mixed experiences. My own bench test showed a slightly rougher spin compared to the Apex RC sets, which is consistent with the 3.9 average rating. The ABEC-7 rating printed on the package is not verified by an independent rating body, so treat that label as a hint rather than a guarantee.
For a tiny whoop where bearings are cheap and the build is meant to be crashed anyway, this set makes sense. For a more expensive motor where smoothness matters, the Apex RC MR115 is a better investment.
Right pilot for this bearing
If you build or repair tiny whoops, 1S quads, or micro cinewhoops, this is the size you need. Pilots who maintain a fleet of small 3-inch cinewhoops on 1404 or similar motors will also reach for this 3x8x4mm spec regularly.
The 10-pack is enough to refresh an entire whoop collection with spares left over. For pilots who crash often and replace parts in batches, the bulk format is more useful than single bearings.
When to skip it
Anyone flying a 5-inch freestyle or racing quad should look at the 5x11x4mm Apex RC set instead. The 3mm inner diameter is too small for 5mm motor shafts. Pilots chasing verified premium smoothness should look at branded EZO or NSK bearings rather than this generic option.
If your motor is a high-end cinewhoop motor that came with Japanese bearings from the factory, replacing with this set is a downgrade in expected smoothness.
5. YijiaLink 16pc RC Bearing Kit – Multi-Size Value Pack for Builders
16pcs RC Ball Bearings Kit 5x10x4 5x11x4 8x12x3.5mm Rubber Sealed Compatible with Tamiya TT-02 TT02 1/10 RC Parts
Multi-size kit
16pc total
Rubber sealed
Pros
- Three common FPV sizes in one kit
- Rubber seals protect against dust
- Stainless steel construction
- Good price per bearing
Cons
- ABEC 3 rating (lower precision)
- Some fitment variance on TT-02
- Not premium Japanese steel
The YijiaLink kit includes 8x 5x10x4mm, 4x 5x11x4mm, and 4x 8x12x3.5mm bearings, which covers the majority of FPV motor sizes plus a few RC car sizes. I used this kit to refresh an entire 4-inch freestyle build plus a Traxxas crawler in one go, and still had spares left.
The 96 reviews averaging 4.3 stars show this is a reliable budget option for builders who need variety. The rubber seals (2RS) are a step up from the metal-shielded budget sets in terms of dust protection, and stainless steel construction helps resist corrosion in humid climates.
The ABEC 3 rating is on the lower end of the precision scale, so the bearings will not feel as smooth as an ABEC 5 or 7 set right out of the wrapper. For freestyle and racing where crashes are common, that precision gap rarely matters. For cinematic builds where vibration control is critical, the premium sets above are worth the upgrade.
This kit is the right answer for hobbyists who maintain a fleet of builds or who want to keep a well-stocked repair drawer. The mix of sizes covers most replacement scenarios without placing multiple orders.
Who benefits most from this kit
Pilots who own multiple FPV drones of different sizes will appreciate having the right bearing on hand without ordering individually. Tamiya TT-02 RC car owners can also use this kit directly since the sizes match that platform.
Workshops, flight clubs, and pilot trainers that maintain a bench of motors will get excellent value from this bulk kit. The price per bearing is hard to beat, and the rubber seals add real-world durability over metal shields.
When it is not the right call
For a single high-end motor where you want maximum smoothness and verified longevity, individual premium bearings from Apex RC or Winter Evening are a better fit. The ABEC 3 precision on this kit is functional but not flagship.
Also note that some TT-02 variant owners reported fitment issues. If you are specifically buying for a Tamiya TT-02, double-check the OEM bearing size chart before ordering.
6. Winter Evening Ceramic Hybrid Bearings – Premium Upgrade for Larger Motors
Winter Evening – for Arrma 3S 4S 6S BLX 3200kv 2400kv 2050kv 3660kv 3668kv 4074kv Brushless Motor Bearings | Stainless + Ceramic
5x13x4mm and 5x16x5mm
Ceramic + Stainless
3pc pack
Pros
- Ceramic hybrid construction
- ABEC 7 precision
- HybridOrange seals
- Pre-lubricated with synthetic grease
Cons
- Only 3 bearings per pack
- Targets Arrma BLX motors mainly
- Premium pricing
- Limited stock
The Winter Evening set is the upgrade pick for pilots running larger motors that take 5x13x4mm or 5x16x5mm bearings. I tested this on an Arrma BLX 3660kv motor from a basher rig and the spin-up felt noticeably smoother and quieter than the stock bearings that came out.
Ceramic hybrid bearings use ceramic balls instead of steel, which reduces friction and wear at high RPM. The 85 percent 5-star rating across 12 reviews reflects the premium feel of this set. The HybridOrange seals are tight and the synthetic micro grease is already applied, so installation is essentially drop-in.
The pack only includes 3 bearings, which is enough for one motor replacement but not a fleet refresh. Stock is also limited on this listing, which means reordering can take time. The price per bearing is the highest in this roundup, but the upgrade in smoothness and expected life is real for pilots who can use it.
For FPV pilots running 6S or 8S heavy builds with motors like 4006, 5008, or Arrma BLX-scale motors that share this larger bearing spec, the Winter Evening set is the premium choice.
Why pilots pick ceramic hybrid
Ceramic balls are lighter and harder than steel, which means less rotating mass and longer service life under heavy load. Pilots who push their motors to high sustained RPM, run long cinematic sessions, or tow cinema cameras will notice less motor heat and smoother low-throttle response.
The ABEC 7 precision rating is more reliable on this set than on generic Amazon listings because Winter Evening actually specifies the materials and tolerances. For pilots who care about verified spec rather than printed claims, this is a step up.
Who should pass
Pilots flying standard 5-inch FPV builds will not benefit from this larger bearing size since their motors use 5x11x4mm. The Apex RC set in slot one is the right call there. Budget-conscious builders will also find this price point hard to justify.
If you are only doing one motor swap and not running heavy cinema loads, the steel Apex RC bearings will give you 90 percent of the smoothness at a fraction of the cost.
7. Hamiey 50-Pack 608-2RS Bearings – Bulk Pack for Builders and Cinematic Rigs
hamiey 50 pcs 608-2rs Ball Bearings 8x22x7mm, Double Rubber Sealed
8x22x7mm dimensions
Rubber sealed
50pc pack
Pros
- Huge 50-pack for bulk use
- Double rubber seals
- Chrome steel quality
- Pre-lubricated
Cons
- Oversized for most FPV motors
- Only fits 8mm shaft setups
- Not the precision tier pilots expect
The 608-2RS is the classic 8x22x7mm bearing found in skateboard wheels, 3D printers, and the larger gimbal and cinema motors used in high-end camera rigs. I keep a pack of these on hand for cinema drone builds that use larger direct-drive motors and for FPV motion rigs in the workshop.
The 79 percent 5-star rating across 84 reviews reflects consistent quality at this bulk level. Chrome steel construction with double rubber seals gives good dust protection and a long service life. Pre-lubrication out of the wrapper means no extra prep before install.
Spin-down was consistent across the bearings I sampled. The ABEC 3 rating is on the lower side, but for the heavier loads and slower RPMs of cinema motors, precision is less critical than durability and seal quality. The double rubber seals hold up well to the dust and debris that larger motors tend to ingest.
The 50-pack format means this is not a single-build purchase. Pilots with a workshop, a 3D printer, or a fleet of cinema drones will get the best value. For a one-off FPV motor swap, this is the wrong size entirely.
Best fit uses
Pilots building or maintaining 3D printers, CNC machines, cinema gimbals, or larger RC vehicles will find this 608-2RS spec at the heart of most of those platforms. The 50-pack covers a workshop’s worth of replacements at a price per bearing that beats buying individually.
FPV pilots running heavy-lift or cinema drones with 8mm shaft motors (rare but exists in industrial-grade builds) can also use this set. Most FPV quads do not use this size.
Why it is not for typical FPV
Standard 5-inch FPV motors use 5mm shafts with 5x11x4mm bearings. The 608-2RS is too large for that application. Buying this for a normal FPV build means you have a pack of bearings that will sit unused.
For pilots who only need one or two bearings at a time, the per-unit cost of this 50-pack is actually higher than the smaller packs above. The bulk format only wins when you have many uses for the size.
8. Horex PFPE Dry Film Lubricant – Bearing Maintenance Companion
Drone Dry Film Lubricant with PFPE 30ml Propeller Shafts Lube Anti Seize Reduces Friction Maintenance Accessories for Agricultural Drone UAV FPV Drive Shaft Motor Bearings Remote Control Toy RC Models
30ml PFPE formula
Drone safe
Maintenance product
Pros
- PFPE dry film formula
- Purpose-built for drone bearings
- Comes with needle-tip applicator
- Resists pesticide corrosion
Cons
- Not a bearing itself - maintenance only
- Small bottle for the price
- Requires shaking before use
The Horex PFPE lubricant is not a bearing, but no best motor bearings for FPV drones list is complete without a maintenance companion. I applied this to a fresh set of bearings before install and again on a worn set to see if it brought them back. The needle-tip applicator made it easy to reach the seal lip without disassembling the bearing.
The PFPE formula (perfluoropolyether) is a dry film lubricant, meaning it evaporates to leave a thin protective layer rather than a wet grease residue. That matters for drone bearings because thick grease attracts dust and grit, which accelerates wear. PFPE resists that issue.
The 74 percent 5-star rating across 131 reviews reflects the niche value here. Agricultural drone pilots especially praise the pesticide corrosion resistance. For FPV pilots, the value is in being able to refresh a slightly noisy sealed bearing without opening it up.
The 30ml bottle seems small given the price, but the liquid is concentrated and a single drop per bearing is enough. If you maintain a bench of motors, this bottle will last through many refresh cycles.
Why pilots add this to their kit
PFPE is the right lubricant for high-RPM sealed bearings because it does not migrate, attract dust, or break down under heat like generic oils. Adding a single drop at the seal lip can quiet a slightly noisy bearing and extend its service life by weeks or months.
Pilots who fly in wet or dusty environments (beach sessions, agricultural jobs, winter flying) get extra value because PFPE resists moisture and corrosion better than standard oils.
Limitations and caveats
This is a maintenance accessory, not a replacement for worn-out bearings. Once a bearing has pitted races or rough spots on the balls, no lubricant will fix it. Replace the bearing first, then use PFPE to keep the new set quiet longer.
Do not apply PFPE to non-sealed bearings or use it as a substitute for proper grease in non-drone applications. The formula is optimized for the sealed, high-RPM environment of brushless drone motors.
Buying Guide – How to Choose Motor Bearings for FPV Drones?
Picking the right bearings is less about brand hype and more about matching the size, seal type, and precision to your specific motor and flying style. Here is what to consider before clicking buy.
Bearing Size and Shaft Compatibility
The most important spec is the inner diameter, which must match your motor shaft. Tiny whoops and 1102-class motors use 3mm shafts with 3x8x4mm bearings. Older 2204 and 1806 motors use 4mm shafts with 4x9x4mm bearings. Modern 22xx and 23xx freestyle and racing motors use 5mm shafts with 5x11x4mm (most common) or 5x10x4mm (some bell housings).
Measure the old bearing with calipers if you are not sure. The outer diameter and width are equally important because the motor housing is machined to a specific fit. Forcing in a wrong-size bearing will damage the motor bell or cause the shaft to bind.
Bearing Materials and Construction
Standard bearings use chrome steel or alloy steel balls with steel races. This is what most FPV motors ship with and what most replacement bearings use. For pilots chasing the last bit of smoothness and longevity, ceramic hybrid bearings use ceramic balls in steel races, reducing friction and weight.
Stainless steel construction is a step up for corrosion resistance, especially for pilots flying near salt water or in humid climates. Ceramic hybrid bearings are another step beyond that, but the cost only pays off on larger motors where the upgrade is felt.
ABEC Rating Reality Check
ABEC ratings (ABEC 1 through ABEC 9) measure dimensional tolerance, not real-world durability or smoothness in a drone application. An ABEC 7 bearing from a no-name brand with poor steel will outlast nothing, while an ABEC 3 bearing from a quality maker can run for hundreds of hours.
Treat ABEC as a hint, not a guarantee. The Japanese big three (EZO, NSK, NMB) generally outperform higher-rated generics because of better steel, better heat treatment, and tighter quality control. For most FPV pilots, an ABEC 5 bearing from a trusted brand is plenty.
Sealed vs Metal Shields
Rubber-sealed bearings (2RS designation) keep more dust and debris out but add slightly more drag. Metal shields (ZZ designation) spin with less friction but let in more contamination. For outdoor freestyle and racing, rubber seals win on longevity.
For indoor flying or clean environments, metal shields give a tiny efficiency edge. For agricultural or beach flying where dust and moisture are heavy, always pick rubber-sealed bearings.
Recognizing Bad Bearings Before Failure
The early signs of a failing bearing are a faint rattle on startup, vibration transferred into the camera mount, and reduced flight time as the motor works harder against friction. Spin the motor by hand (unmounted) and listen for grinding. Any roughness means it is time for a swap.
Do not wait for the bearing to seize. A failing bearing pulls extra current, heats up the motor, and can damage the stator windings before it actually locks up. Replacing bearings early protects the much more expensive motor.
Frequently Asked Questions
Which bearing brand is best for FPV drone motors?
The Japanese big three (EZO, NSK, and NMB) are widely considered the best motor bearings for FPV drones because of consistent steel quality, tight tolerances, and reliable seal fit. Among the Amazon options in our roundup, Apex RC Products offers the most consistent quality for the standard 5x11x4mm size used in modern freestyle and racing motors.
What size bearing do most FPV drone motors use?
Most modern 22xx and 23xx FPV motors use 5x11x4mm bearings on a 5mm motor shaft. Smaller motors like 1102 whoops use 3x8x4mm on a 3mm shaft, while older 2204-era motors use 4x9x4mm on a 4mm shaft. Always measure the old bearing before ordering a replacement to avoid a mismatch.
How long do FPV motor bearings last?
Quality bearings in a well-maintained motor typically last 300 to 500 flight hours before noticeable roughness develops. Pilots flying aggressive freestyle or in dusty environments may see bearing wear much sooner, sometimes within 50 to 100 hours. Replacing bearings at the first sign of noise protects the stator and keeps the motor efficient.
Should I lubricate FPV motor bearings?
Do not lubricate sealed bearings unless using a dry film lubricant designed for high-RPM applications. Standard grease attracts dust and grit, which accelerates wear. PFPE-based dry film lubricants like the Horex option in our roundup can quiet a slightly noisy sealed bearing and extend its life without the contamination risk of wet grease.
Are expensive bearings worth it for FPV drones?
Premium bearings from EZO, NSK, or NMB are worth the upgrade for cinematic and long-range builds where smoothness and longevity matter most. For freestyle and racing where motors are crashed and replaced regularly, mid-tier bearings like Apex RC MR115-2RS deliver most of the performance at a much lower cost per rebuild.
Final Verdict on Motor Bearings for FPV Drones
The right motor bearings for FPV drones come down to matching size to your motor shaft and trusting the brand behind the steel. For the majority of pilots running 5-inch freestyle or racing builds, the Apex RC MR115-2RS 5x11x4mm set is the safest, most affordable pick and earned our Editor’s Choice badge. Budget builders with smaller motors should reach for the FUSHIBEARING 684ZZ or Apex RC MR105ZZ depending on shaft size. Pilots running larger motors who want the smoothest possible spin should upgrade to the Winter Evening ceramic hybrid set, and any pilot maintaining a fleet of motors should keep a bottle of Horex PFPE on the bench for refresh cycles.
Whichever set you pick, replace bearings at the first sign of noise rather than waiting for failure. A fresh set of quality bearings costs far less than a new motor and will keep your packs smooth, your footage vibration-free, and your flight times consistent.
