Sorry for being gone for so long! This is a tank I built. It uses a skid steer turning system which i used in several of my erlyer projects. I have taken down the uss tiny many times with it. It is a fully caipable land and water veihicle, but i would not sugjest it for offroading. It is not to stable, so i put a gyrosocope in. It is especially necisary in the water. Activate 1 activates lights. Activate 2 activates the gyroscope. And activate 3 activates water mode. Water moad basicly activates the propellers, and then lets you steer with the gyroscope. Sorry for all the typos, i am on mibile right now. Controles for wheels are same as normal, (pitch/roll) and for water it is throttle and yaw. Thanks for upvoting! Also, i do take sugjestions for builds, so if you want me to do somthing tell me in the comments. (It also gives me fun ideas to prqctice on)
