► 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. ⚠Please also watch Chris Rossers videos about motors:⚠ https://www.youtube.com/watch?v=RXy00orSpfU&list=PLFPBjpbd5xKSUeHAB0K-jzTpmQRLRl7AA&index=1 https://www.youtube.com/watch?v=llmRHawsXZ4&list=PLFPBjpbd5xKSUeHAB0K-jzTpmQRLRl7AA&index=11 https://www.youtube.com/watch?v=C1Xpt0y2-KU&list=PLFPBjpbd5xKSUeHAB0K-jzTpmQRLRl7AA&index=13r-proportioned

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.

Danke für die Infos :)

Wieder sehr gute infos👍👍👍

Great video 👍🏻

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

Thank you for sharing! How much weight do you save cutting those holes into your BT2.0 connectors?
-
I also use rcinpower 0802 22000kv but I think the cable is not good so I replaced it
-
Hi, can you help me please ? What I should buy ? For outdoor fliyng. Meteor 85 or Mobula 8. Thanks
-
I have 0802 25.000kv rcinpower on 5A ESC. Will that be fine?
-
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.

Possible to share your throttle mid , expo and the scale ?

Lol the whiffle ball canopy... i cant take you seriously
