Hi, I have an Xera 4020-1000KV 2Y motor can you please tell me if this would work in a Trex 500 L and what head speeds I could run

Regards

The trex 500l uses a 1600kv motor. A 1000kv motor would only get you around 2000 rpm which would be fine if you are just doing circuits and maybe a bit of sport flying, if that is all you do then the motor would actually be beneficial to you as it would drastically increase your flight time. To get that motor to work for 3D and have the same head speed as a stock 500l you would need a 17-19 tooth pinion. The other option wouldn't be to run it on 8s using 2 4s packs but you would also need a new esc to handle 8s.

You also first need to check if it physically fits in the heli and that the shaft is the same diameter.

60% of the time, it works every time!

And also worth saying is the stock 500L Align motor is very good and hard to beat.
