RE: catamaran hull on ebay
This hull is identicle to the EKOS hull except for the fancy stuff on top.
The paint work is nice too I heard.
It can handle twins. Nice setup is a pair of UL-1 motors, x442 L&R props and some Turnigy 180 esc's Fairly cheap and robust.
Actually you could easily use a SupepSimple 90/100 amp esc $27, and waterproof it and it will handle those motors fine.
