For a bit of fun i decided to knock up another airboat for rescue and camera work. made from a $19 body board with a 3542 1000kv TGY outrunner running on a 4s Lipo, with a 10x6 pusher prop. Went fairly well on it's first test using only about 30% power, but needed some up thrust and rudder trim for much more throttle. Probably needs some small bottom strakes to limit the drifting tendency and make it easier to control, (did this with the first airboat which manages 30kph)
Could quite easily run on 3s for more economy, as it planes very easily. I got 20mins almost continuous running at the speed in the video, (on 30%) which is more than adequate, as it would be just idling around for videos. Quick to make and lots of fun. Motor mount screws onto 4 -30mm dowels epoxied into the body board.
