Hi.

I am wanting advice on putting an electric brushless motor Into my brother's 36" Vosper RTTL (built In 1960) which I am rebuilding for him. I am leaning towards 1 pf 2 motors from Hobby King.

2848SL 3900kv Brushless Inrunner (WaterCooled)
or
3660SL 3060kv Brushless Inrunner (WaterCooled)

The original engine was diesel powered with a 3-bladed, 40mm propeller which I still have and wanted to use.

I figure that a 70amp SC would suffice. I would like to get about 20 minutes cruising speed out of the battery. Would nMh batteries do or should I go for Lipos?

Can anyone steer me In the right direction?

Thanks, Ian Downunder
