Hi all finally finished my jae .21 installed a Leopard 3674 1900kv motor a 120amp Seaking esc and a 4s 45c lipo.What size of prop would be a safe spot to start testing this set-up ? Regards Andris Golts.

I would upgrade the esc for a T180.Gill

Try something around 440, 442, 642, 445 range, the T120 should be ok if the motor is not over propped on 4s, do usual run for 1 min and check temps, then longer runs and keep checking temps on motor, esc and batts.

Thanks for the great information. Regards Andris Golts.
