RCU Forums - FUN JET CATAPULT.

Vert effective! Can you elaborate on what you used to build it and any specs that you are willing to share about it. I'm stuck in a flying alone most of the time and with my back and neck problems, I can't hand launch any aircraft.

I thought about building a catapult by doing the following: 2' X 8' X 1/2" plywood. I have a long bungee coard that'll stretch easily the 8'. Use a two parallel pieces of wood with a pin between them tied to fishing line. Aircraft attaced to the bungee coard by U shaped loop attached to the nose of the aircraft and back to the bungee coard. Aircaft to full throttle, pull the pin, and the bungee coard would launch the aircraft. That's the gist of it anyway. All in my head at this point.
