hi i'm a beginner ,learned with eco piccollo,then progressed to collective pitch piccollo,now i'm flying caliber 30 glow engine,i've had about 1.5 gallons through of molecular blend,i am fortunate enough to have recently joined a club,and i'm doing quite well.The manager at the club helped me with my first flight ,ie.helped me trim the heli and adjusted the engine after first and subsequent flights,sorry to rattle on but i must advise you to not try flying glow helis on your own!!!even if you have no club locally,get a mate to accompany you,these things are very dangerous and you can't be too careful,also your bmfa insurance would be invalid if flying alone..as for your cut out probs,is your engine brand new??if so you should be running it at least 2 full turns out from the recommended adjustment on the carburettor thumb screw settings,a plume of smoke is an ideal indication of correct carb settings ,,hope this helps
