All swapped over, gone from 480 can motors with 9.6v Ni-mh to E-MAX 1500Kv brushless with 11.1v 5500mAh Li-po battery. The Li-po battery is about 2/3rds the weight of the Ni-mh and the motors less than 1/2 the weight of the old can motors. Power should be 300watts. Just need some wind/snow/hail/rain free hours over the weekend to test.
I was going to just swap the motor mount plate to the rear position in the engine bay but the new motor wouldn’t centre on the plate.
So mounted to the front and trimmed the back part of the mount down to sit the props as far back as I could go
Final position, shortened the mounts by about 15mm
Started the brushless swap on the Twinstar, so far carefully cut out the engine mounts so I can move them back enough to mount the new motors on the front of the engine mounts. Also cut a channel in the wing to get at the motor loom, will epoy it back in when I fit the wiring for the new speed controllers.
Managed to get a couple of flights in on the Twink. Camera working okay this time Managed to bash one of the aileron pushrods walking into the field which bent it slightly & required a bit of trim on the first flight, other than that and some poor attempts at landing on the narrow track in the long grass some good flights. Looks like the field will be cut for silage shortly so will try and get the Travelair out for some nitro flying
