Out of Foam Board!
I have two 4s lipos and a power pack F motor. They're from a plane that keeps flying worse and worse every time. Eventually I'll have to take the electronics out of the long wing sparrow, likely after a bad crash. I saw some ground effect designs that I could mimic to fly off of snow and in the neighborhood. I also have a makeshift ice rink in the backyard that sometimes melts, which would be cool to fly on. I would need to install an elevator to keep it from flying too high or lawn darting, and a rudder for steering.
