RE: JEH Ignition
OK no name calling or finger pointing.
Basic fact the Timm 4 and 6 are not designed for high speed operation. Look at the engines that are on the JEH site. This ignition is for them and IT WORKS VERY GOOD when used as designed. You can make it run on a weedie with a little engineering, but often you exced its design specs. A few more parts and more $$ you can add a latching hall or even build the auto reset RC circuit. But again you are asking it to do something it isn't designed to do.
If you enjoy the challange of doing stuff like this and have the ability, way cool, but there are folks who can't. Thats where RC and CH come in we design, sell and make a living at, conversion kits that the average modeler can install on his weedie engine and convert it to a model engine. These kits are simple to install and are designed for this use.
By the way we got one of the two Blue light ignition kits back. It looked like somebody had used a 100w solider iron on it and it would not work any more, it took about an hour to repair it. Thats why no more blue lights
If cheap is your operating mode, fly it on the magneto using Carr or Wacker parts. There lots of these mag conversion flying and the owners are having a blast with their plane and engine. However if the "need for speed" rears its head we are here to "help" with your problem.
I had a article published about 8 years ago in High Flight about converting the Mac 28 and 32 engines. At that time there were almost no 30cc sized gassers, so the weedies made good $$sense. But even then I warned about have a $300 conversion, a CH kit and a tuned exhaust, in a $25 engine. Each to his own need and budget.
Lets have fun and get some flying in.
