I bought Graupner Speed 700 Turbo S, hope to be overvolting it to 12v (it's a 9.6), and i think i'm gonna chop off a good 10cm off the back of the boat...i tried it in the bath, and it's got more than enough flotation to handle the weight. Btw - i weighed it.....far from the 400g i was telling you about, it weighs a brick-like 1kg. With cells and all i think it should weigh in at about 2kg...is that too much for a 70cm boat?
