I appreciate everyone of you for giving great advice and I find RCU an incredible source of info and news about our great hobby.

I am very encouraged Coupar by your results. I will definitely try your suggestion and go with the simple on board glow solution.

One question though, should I go with a 1.2v Ni cad or 1.5v alkaline. Also, should I go with a hot or cold plug. Since I am concerned about all this extra heat from the battery on top of the heat from the combustion.
