Ive been messing around with some stuff for a few days and finally found the best way to build it. Instructions: before driving or doing anything, turn on 2 and 5 and vtol up to raise the boat engine in the back. Press 4 for rear wheel drive, which does alot of wheelies. If you do not want to do wheelies, press 7 instead of 4 and that turns on front wheel drive. When entering water, first go into the water, then lower the boat engine by pressing 2 and 5 and pushing the vtol to the middle, push the trim up, and press 1 to activate turning and prop on. Use throttle for forwards and roll for steering. Do the opposite when going back on land. Hope you enjoy :)
