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.
Recommend, light, powerful, hope for more M3 propellers
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.
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!!!
Worth the money! Can't go wrong.
