I actually like both glow and gas. I have one 50cc plane and just got another because I like that size enough to do so. BUT I have another 12 planes that run on glow and all at this time are 4 strokers. To me the glow fuel is just a necessity to enjoy the hobby, as much as fueling up my car. I get my 15% Cool Power or Omega from a big LHS in Beaverton, OR, and they sell it pretty cheap plus give a buck off each gallon if you buy a case (4 gallons and can be mixed %'s)...it comes out just $15 per gal. I think I use about 15 gallons per year. That is just about $225 per year for glow fuel. Geez, that's not much for the amount and frequency of pure enjoyment I get out of this hobby. And nothing smell as good as glow fuel exhaust early on a morning at the field...well, except for bacon frying and coffee brewing! Jon
