Think about this,I converted a four-stroke backpack blower into an aircraft engine for under $150.Power about equal to a G62.How much would the battery bill be for a small 1/3rd size airplane(not to mention the ESC and motor)?I get a better sound(no WHEEEEEEEEE..),no mess and fuel at the cheap price of @$4 a gallon.Now, before all you electric guys start coming over to my house with torches a'burning,let me say that for anything smaller than a .25 glow motor I do not bother with glow and have been going electric.

Back to the main topic.Lots of good advice here.The one thing I didn't see mentioned is that it possible to have a nice idle and a nice top end but still have it "stumble" or quit altogether when transitioning from idle to top end.When the engine is at idle,pinch the fuel line.If it dies right away,the idle mixture is too lean(usui).If it keeps running and then gains RPM before dying,it is too rich(amai).Words in parentheses are for Don.

Gambatte!
