But that is exactly my point...

To me it would be a lot less hassle to balance my plane for the little bit of extra weight either a magneto or elec-ign would add... but thats just me... I like to tinker around with different things too, but I wouldn't risk putting something so unreliable on one of my planes... If you really want to run glo plugs why not just use regular glo-fuel in them? expense?

If your in the hobby... spare no expense on your equipment... strive for the best...
