made a little modification my guess is its gunna burn out the little motors but i used two butchered servos which i learned to do way back for robots or when i used to make mini ww2 tanks and used them for drives(pretty strong) but i stripped them and put them in seems to work alright im the bathtub, forward and reverse works alright just need to hook up rudder next and i have a perfect idea for that, but what i noticed out of the older futaba servos gave me the perfect motors to mount to the existing mount all u have to do is use the one mounting peice where ur shafts would of exited and then take out the plastic bearing and ur left with three holes. middle largest which need to be reamed to fit the motor and the other two beside it surprizingly matched up perfectly to the mounting holes on the motors, shocked me made life so easy, so anyways that basicly what i did, see what u guys think of the pics, will kinda explain themselves
