Bought on Ebay and was originally fitted with speed 900 type motor.
I tried this set up on 12V but was disappointed as it did not come onto the plane.
I planned to increase voltage to 18V from 3 x 6v batteries but not tried.
I have now obtained a 3KW watercooled brushless motor and want to fit it with a 200A watercooled ESC. not yet tried as I need a motor mount.
I will update later with results. (Motor: TURNIGY 4084 620KV) (ESC: 200A WATERCOOLED) (5/10) I have since put in the water and suffered a broken coupling. Looking for a suitable brushless coupling to M4 shaft.
