► What you need to pay attention to when choosing a motor for a race whoop:
(for FULL SEND RACING)
● Motor size → I prefer 702 for 65mm, 802/1002 for 75mm, 1102 for 80mm (75pro) and 1103 for 85mm 2S
● Power and torque → For me I prefer highest power which is only possible with high kv motors
● Internal resistance → I prefer lowest possible
● Motor shaft material → Not too hard and not too soft (balance between hard and soft)
● Motor shaft diameter → I prefer short 1,5mm shafts if possible. 1mm in rip quality is also ok.
● Bearings → I prefer double ball bearings in high quality (important!)
● Curved or flat magnets → I don`t care too much. Curved if possible.
● Weight → I prefer lowest weight if possible
● Motor cable length → I prefer longer motor cables if available (not too tight fitting)● Designe → I prefer simple lightweight designe with only 3 thin struts
● Motor cable mount → I prefer a small lightweight PCB board
My dreammotor would be a 03 size high kv motor (better throttle response) with the efficiency and low internal resistance of a 02 size motor (on all whoop sizes). And of course with short 1mm/1,5mm shaft in a good material, high quality double ball bearings, pcb board, long enough motor cables and simple lightweight designe with only 3 thin struts to the motor bell.
► Motor screws:
● Reny (lightest) or PEEK in M1.4mm x 3.0/3.5/4.0mm for 65mm Whoops
● Titanium in in M1.4mm x 3.0/3.5/4.0mm for 75mm and 80mm (75pro) Whoops
● Reny M1.6mm x ?mm for 85mm Whoops with 1103 Motors
⚠️‼️⚠️ My secrets for flying well with high kv motors:
● BT2.0/A30 Main plug
● AWG20 Main cable
● No motorplugs (directly soldered cables to the pads on the flightcontroller)
● ESC settings tailored to the motor (e.g. Bluejay 96khz and motor timing low for 802 27000kv)
● Low pitch propellers (watch my video about propellers)
● Using betaflight settings for better throttle control (Throttle MID, Throttle Expo, Throttle Cut Scale)
● Using the best lipos on the market with the highest C-Rate (lowest internal resistance)
⚠️‼️⚠️ There are quite big differences in motor quality. For me, only rcinpower has the best overall quality so far to this date (23.5.24)
⚠️‼️⚠️ With rcinpower motors it is important to secure the motor cables with a rubbery glue on the PCB on the motor (I use uhu por glue)! As well as attaching the motor cables to the struts of the whoop frame with dental floss so that they cannot move too much.
⚠️‼️⚠️ My experience has shown that every motor has an area in which it is most efficient (watch Chris Rosser's videos) Normally this is around 80% throttle. That's why you should choose the kv so that you never have to give 100% throttle in order to be as efficient as possible. That's why I like to fly with engines that have a little too much kv. When racing, I move most of the time in 0-80% of the engine's throttle range.
⚠️‼️⚠️ Flight times: Of course, flight times vary greatly depending on how fast you are flying.
The flight times on my for racing perfected whoops are all about the same. About two to two and a half minutes at full send racing. And up to 5 minutes when cruising.
❓❓❓Why rip 802 27k AND rip 1002 22k Size for 75mm Race Whoops?
● Rip 802 27k for 10A or 12A ESC`s/flightcontroller and tracks with many narrow slaloms and changes of direction where it is important that the outside of the whoop is less weight or the center of gravity is more compact. And for frames where only 802 motors fit through the frame (so that you can solder the motors on the flightcontroller before mounting the electronics into the frame)
● Rip 1002 22k for 5/6A ESC`s/flightcontrollers
⚠️‼️⚠️ My experience and all my knowledge about whoop motors for racing correlates perfectly with the scientifically developed knowledge that Chris Rosser has. Please watch his videos about motors.

‼⚠Addition to the video description:⚠‼ The reason why these motors and motor prop combos are my favorites: They are not over- or underproped. Motors with too big propellers (overproped) are less efficient (in full send racing operation) and less responsive (due to lack of torque), which means poor handling in fast direction changes (e.g. in slalom). The same efficiency problem applies to motors with too small props (underproped). For someone who flies slowly (cruising or very slow racing), slightly overproped can be interesting (e.g. 1002 with 2inch propellers or maybe 702 with 40mm propellers). But for me as a full send racer, I definitely don't want overpropped. Better slightly underproped. Or ideally, of course, perfectly in the middle.

Thanks for sharing, I haven't tried all those sizes.
RCinpower are my favorite too, super reliable, efficient, and powerful. Even the 0802 22k kv is better than some other brands 25k.
Never broke a shaft. People who don't know think they need 1.5mm shaft, that's becoming a big misconception in the community, and that is limiting people choices in 0802.
I freestyle, 25k with biblade on light builds and surprisingly 22k with triblades for heavier hd builds gives perfect flight time and power (75mm).
Only drawback: some props are a bit loose and get ejected in crash, I solved this issue by adding dental floss inside.
That's exactly how it is! Thanks for your feedback! By the way, I also use dental floss on all props. I first drill them with 1mm or 1.5mm pcb drills. This way I can easily switch between props..
Aaaah so my new rcinpower props do feel loose. I was wondering about that because on my old beta 1102 the props were much tighter
@@Aldrizzle I use dental floss on all props. I first drill them with 1mm or 1.5mm pcb drills. This way I can easily switch between props..
Danke für die Infos :)
Gerne! Ich hoffe es hilft einigen Piloten..
Wieder sehr gute infos👍👍👍
😃🤜🤛
Moin, vielen Dank für die Infos! Hatte letztens die gezeigten 0802 in einen Meteor75 Pro frame verbaut und war mir nicht ganz sicher ob die wirklich für 75mm gemacht sind, bin aber erleichtert das ich nichts grob Falsch gemacht habe :D
Sie sind jetzt schließendlich doch in einem 65mm frame gelandet weil der Peak power verbrauch die Flight time sehr beeinträchtigt hat, aber das Flug gefühl war dafür ziemlich klasse. Vielleicht investier ich mal in Akkus mit mehr mah und probiers nochmal irgendwann
Hey gern! Danke für das Feedback! Also du meinst schon den alten Meteor75pro frame? 40mm Props? 802 27k Motoren sind gut für 40mm Props, jedoch nicht für 45mm Props.. (für racing) Ja voll, in gute Lipos investieren ist immer sinnvoll! Meine favoriten für 75mm racing whoops sind: GNB 1S HV 380mah 90C A30 und GNB 1S HV 530mah 90C A30 (hat masse und gewicht eines 450er Lipos)
Great video 👍🏻
Thank you!
I also use rcinpower 0802 22000kv but I think the cable is not good so I replaced it
I thought replacing cable is impossible for tiny whoop motors. Could u please show me any example videos if possible? Thank you!
Yes, you have to secure the cables on the pcb with a rubbery adhesive on rcinpower whoop motors....
@@TamilMediaTV Possible on motors with a smal pcb board.. Like on rcinpower motors..
@@butterflyfpv Thank you mate. I try to figure out. Mine is happy model 0802 19000kv
@@TamilMediaTV EX0802 19000kV? If yes then it is possible..
Thank you for sharing! How much weight do you save cutting those holes into your BT2.0 connectors?
Not measurable on my scale. But I know from experience that a lot of small things together create something bigger. But it's definitely not necessary to do that. But I do it because I don't want any unnecessary weight on the whoop..
Rcinpower hat neue 0702 motoren, falls es dich reizt die zu testen.
Hab noch meine Rcinpower 0802 25000kv mit dem HM diamond AIO.
Funzt noch gut.
Wie du sagstest sind die 27000kv motoren nur für 12A aio.
Die HM 0802 motoren sind gut, so lange soe halten. Das war bei mir leider nie lange.
Rcinpower und tmotor sind allgemein die besten.
Wobei VCI einige motoren für betafpv mittlerweile macht. Die scheinen auch nicht schlecht zu sein.
Ja voll vielleicht kann ich die 702er von rcinpower mal noch testen. Oder auch die rcinpower 703 27000kV. Aktuell allerdings noch nicht erhältlich auf aliexpress oder in europa..
I have 0802 25.000kv rcinpower on 5A ESC. Will that be fine?
Yes! Perfectly fine!
Hi, can you help me please ? What I should buy ? For outdoor fliyng. Meteor 85 or Mobula 8. Thanks
They are about the same.. I can recommend both. Maybe you can start with mobula8? Lighter (?) and better cam. Are you aware of the Betafpv Meteor75pro? A 1S whoop, which is also good for outdoor flying..
@@butterflyfpv I have meteor 65 pro. I want try something more powerful. Meteor75 is 1S. Thanks, I wil try Mobula 8.
@@detomatorcz910 Ok yes then mobula8. A solid whoop.
Possible to share your throttle mid , expo and the scale ?
Test it yourself as this depends on the motor.
1) put the throttle on the odd
2) fly as flat and low to the ground.
3) do some turns and so on but level and close to the ground
4) note the throttle. Mine for a 0702 25000 was around 40%
5) go on beta flight and put mid at 40 and put scale at the top.
6) repeat the low flights and assess whether it suits you.
7) play with expo and mid sensitivity if you feel it is too fidgety. I’m using 15% but still not totally convinced (I flew several years without any expo, so need to re-wire the brain).
8) send it!
I'll make a video about it at some point. A good starting point: I set throttle mid to 0 and throttle expo to around 40-60% on a high kv motor. I like my whoop to have a throttle position of about 40% when hovering. Not everyone likes it, but I like it. I don't like it when my throttle position is at 20% when hovering..
@@butterflyfpv that's a lot of expo!!!
@@nikotttin Yes! Not for everyone I know.. But you can get used to it. And in the rc aerobatic model world with rc 3D aircrafts, everyone flies with 40-60% exposure. It's normal there...
Lol the whiffle ball canopy... i cant take you seriously
😂👍 whiffle ball canopy is a good name for it..
