I've been running Byron's 10% nitro in all my glow engines. I did notice however that my Pete 'n Poke (saito .56 w/12x6 prop) flew like a wet noodle. Yes its got a draggy type wing and airframe but I had plane at just about full throttle the entire flight.
My other planes have OS, Thunder Tiger and Evo .46's. They fly fine with Byrons.
A guy at the field the other nite was telling me he switched over to Cool Power 15 %. He claims a performance was much better plus,
4 strokers like the higher nitro content. So, I bought a gallon of 15% cool power.
Also, while on Morgan Fuel's website, they were saying about draining your tank at the end of the day into you fuel jug. Basically,
it contaminates the whole gallon because during flight, moisture forms inside your plane's fuel tank Morgan says to just drain out all the fuel at the end of the day. So, is this a ploy for people to pucrchase fuel all the time?
