I have been happy with my DLE engines, something is just not right with my 30. There seems to be this montra to chase light weight all of the time. This is fine but it depends on the type of plane. Warbirds need nose weight. Also, I bet there is little difference in weight between a mag engine and an EI engine. All of the mag weight is concentrated up front where you need it. With an EI engine it is in the ignition and battery. These can be placed anywhere I suppose.
With an EI engine there is another battery to deal with, a variable for failure really. In all of my years of flying, the batteries were the weak link. If I can avoid them I do. For sport flying fine. It is too bad the EI will not take a good cell technology without a regulator. I am using Eneloop cells with mine that seem to be the best, but I would like to use a lipo or something else.
It is too bad that with this modern tecknoligy some company or some people cannot come up with a mini-mag ignition on the engine. No battery pack at all. Fixed timing is fine for 30cc engines and smaller. Only reason why this has not been done...there is nobody trying to accomplish this small item!!!! We got to drive this home to the engine builders. Its high time to get it done!!!!!!!!!!!!!!!! Capt,n [img][/img] [img][/img][img][/img] [img][/img] [img][/img]
If you would like to look back a bit there was a manufacturer that tried to make a mini mag. That was Malony (sp?). It worked but you had to spin it 2000 RPM to get it to start.
I think the answer to small engine ignitions is the the piezoelectric transformer but you will still need a battery.
How about this Idea. Just add a circuit so you could plug in a battery for start-up. Kinda like a jump start. As soon as engine is going...just un-plug the jumpstart battery. Or something simular to that idea. If people just take the time to keep this idea up it will happen. It may be some guy with the "right stuff" that does it. He will sell a bunch for sure if it works good. Best Regards Capt,n
