rebuilder, your correct, got it down the lake today and put it in the water, i could p*ss faster than it went, but your right on the motor, i will be going with the motors people suggest, thanks for pointing it out mate

i've had a look at the fiegao motor (580) and worked out that with a
- 6s would give 101587.2 rpm's
-3s would give me 50793.6 rpm's

and so on, i was thinking of 2 x 3s to balance the boat as i already have the battery mountings in place, im just worried that the motor won't cope with the power
