FPVCycle 21mm Motor - M3/M5 Prop Shaft
Choose options
The intended use of this motor is specifically for improved performance on sub 250g 5” crafts compared to other current options. The motor size is 2104 which will give you a noticeable control performance improvement over the popular 2004 size while weighing about the same thanks to the new lighter shaft design which is compatible with future M3 mount props and is fully compatible with existing M5 mount props.

Customer Reviews
I use these to power a spinning blade in a 150g combat robot and they are very powerful and light. The 3mm threaded full-length shaft makes them very robust.
Ummagawds Aerolites and Brother Hobby TC 2004 motors used to be the kings of lightweight 5" motors, both at ~15g a piece. Both feel underpowered though, and using high KV/6s just reduces efficiency and flight time.
These are the next evolution of Sub250g 5" motors. As light as the previously mentioned 2004 offerings at ~15g per motor, but 1mm larger stator diameter provides a welcome increase in torque control and slightly more power. Enough in fact to swing a normal 5" prop like a Gemfan F3S or an Ethix PBJ.
wish these were available in higher kv for 4S 4inch open props
I'm using the 21mm 2300kV motors with 6S 650mAh and 850mAh batteries and absolutely love the flight time and performance! I'm more of a park racer and every time I fly I fall in love all over again with my build. I really love these motors and on a 4" 180g quad like mine, the performance on a 6S light weight battery is very enjoyable. Bob please don't ever stop making these 21mm 2300kV motors!!!
This motor is great when paired with a 5 in sub 250 auw build. Looks great and is very responsive!
Was recommended to try these motors for my 3in apex. Bad idea. Not enough power / Apex frame is to heavy. I am sure they would be great on a 200g quad.
Worth the money! Can't go wrong.
21’s will be my new standard for sub 250 builds.
Sad to say I am one of those who stays in a country where there is a 250g limit. I used the motors for a Fouride build and managed to get its AUW around 250g with a 4s 450g lipo. Going to get more for my bext builds.
I got the 2300kv on 4s 650mah onToothfairing and 6 7 min cruise. I feel much better control and power than 2004 motors on same controller and pids. Really surprise how they sound...indeed remember me like a tie fighter
Let customers speak for us
I had the older 2 generations of these motors and they keep getting better. Thicker stator, thicker stator base and they look amazing!
Pared this frame with a o4 lite and a Matrix 1s fc. I will always have a Babytooth in the fleet. Pic is weight with o4 lite.
these motors are nice and smooth on a 1s build!
Now even better with o4 lite!
Truly a fantastic frame!!! The only shame is that I have to pay duty to get your wonderful frames. A sacrifice I'm happy to make!!!

Great frame, durable and cheap

Great frame. Great flyer.
Worked very well easy to solder flies great very fast and responsive
The best motor I’ve ever tested
This is the best motor I’ve ever tested
These motors are so smooth and have so much power. I have them on a light weight 5” and it has to much power I had to limit the power on them. Great durability as well. Taken some hits and still running smooth.
👍
Well packaged and a nice varity of mounting bolts
