Art,
Here is the one I've used for 26 years. Made it out of junk that was sitting around. Wheels let it move, spring scale lets you compare static thrust of engines, tuning and mods. I use two lines - the spring scale line, and a backup safety line that's a little longer in case the first line/scale fails. The second (back up) line also pulls the kill switch to shut down the engine if it gets pulled tight.
