I was looking at Brodak's Merlin glo plugs and wondering if they're as good as Thunderbolts, which I can't seem to find anymore.  I've been using the Thunderbolt RC plug with idle bar, and they have really been good for RC, and the few times I've used them in CL engines (haven't flown much CL in a few years due to health reasons, and lack of a good place to fly).  Hope to get behind the handle this fall.

They are  excellent  plugs  I have them in stock  for  2004  and  2005s
