Ah the things we tinkered with when we were kids. Crashed my last control line model at the end of the season (winter was for building). After the first snow we were bored to tears so I took that Cox 049 and mounted it to a wire frame soldered to a pair of old curtain rods that formed skis. On soft snow it didn’t work worth beans. On packed snow it would take off but would slow down and stop in any kind of soft stuff. We built a banked oval in the front yard about 20 ft long packed and iced. It started out slow but when it built up enough speed so it wasn’t dragging on the bottom lip it picked up speed like crazy. The higher up the bank it went the faster it went. We ended up watching from behind the tree not knowing how to stop it. Finally it left the track and hit the screen door on the front of the house knocking the lower aluminum panel right out. My Dad was standing in the doorway watching what we were up to. He spanked my ass for busting the door.
