AboutKen Myers Expertise I can answer beginning, advanced and expert questions about electrically
powered R/C model aircraft, and many questions about R/C model aircraft of
all types, except helicopters. I`ve been building, flying and designing R/C
model aircraft for 40 years.
Experience I have been building and flying radio controlled model aircraft since 1960. I'm the president of the Electric Flyers Only, Inc., located in southeasten Michigan. I'm a past president of the National Electric Aircraft Council. I'm vice-president of the Midwest R/C Society. I was president and main founder of the UFO (Union Lake Flying Organization). I've built and flown most types of model aircraft except helicopters.
Question Hi, I have flown my plane twice. Since then my brother tried to start it - I think he changed the inlet fuel and outlet pipes, anyway -he couldn't start it. I have since put the inlet pipe back to normal -it nearly started. I then left the carb open and let it dryout -I left it for two days. I just tried to start it and it is completely stuck! Looking into the exhaust outlet it is all gunked up -kind of thick whitish slime. Can I repair this engine or has it had it? And was it due to leaving the carb wide open for two days. Many thanks, James G
Answer Hi James,
This is a little hard to answer, because I don't clearly understand the terms you are using. If you meant the needle valve when you said "inlet fuel", then changing it can make the engine harder to start. I'm not sure what you mean by outlet pipes. It is not unusual to see "stuff" on the piston. The type of fuel you are using makes a big difference. It is not normal for a glow motor to have the piston "stuck" after just setting for a while if you don't use after run oil. It usually takes many months for a piston to "stick". Leaving the carb open had little to do with it. The engine can be disassemble and cleaned and put back together. Most modeling magazines have "engine" columns what cover disassembly of various motors and how to clean them. You should also be able to find some tips online about what types of cleaning solutions to use.
