RE: Engine Test Stand
I built this as a permanent stand for the club field.
All a member needed was his own piece of 3/4" ply that had the mount for his engine attached to it. My small engine plate had four different size plastic mounts permantently bolted on it- to change engine sizes I just rotated the plate on the main stand.
Construction was out of 2 x 4's and some srap 1/4" ply. By pulling the bolts on the top of the metal straps the unit would fold down flat. There were two clips on the oposite side of the base to hold the re-bar stakes as well as a carry handle.
It was built to handle upto a 100 CC engine.
I used a simple lever throttle at first, but latter used a servo and a home brewed servo driver- no need for a transmitter pin.
