RE: GP Trainer Sixty
Very nice! I haven't gotten to mine yet. Building a Thermal Charger at the moment then a 1/4 Scale Super Cub.
I decided to go electric on my Trainer 60. Also I'm planning on building two of them at the same time. As an Uncle of mine has shone some interest in RC so I thought I'd set him up with a nice trainer. As of now he has a funky old Eagle 50 that someone dumped off on him.
This is the eletric setup I'm planning.
