[] We are new to r/c planes and have purchased two Tower Hobbies 40MKII Trainers. We are having trouble with the engine, which is a .46 Tower Hobbies two stroke. Idling is the problem. We can make the engine run fine at full throttle and at half throttle, but when we bring it back to idle to land the engine dies! Creating an awful lot of dead-stick landings. We are running 15% Omega fuel and have a Tower Hobbie glow plug in the engine. The idle mixture needle is set to manufacturer's specs and the high speed mixture is three to four hundred rpm off of peak. Curious about a hotter glow plug or maybe 30% fuel. Open to any suggestions. Thanks!!
