Speed Boat 2 RC

My first speed boot http://www.thingiverse.com/thing:312235
was enlarged bit by bit of three different parts. This time it should be a hull as if made from one piece with no need of spay rails. Additional it has a deck now to protect electronics. If you seal it with elastic tape and use a compensator grommet for the rudder steering rod it can be unsinkable, but I hope there is no need ;-)
The overall length is 414mm.
The camera mount is provided for this case for mini cam
