I have a few questions about my engine on my high wing rc trainer plane?
on the side of the engine it says SC and on the other says 75. but looking through loads of pics it looks like an aps 75. the main problem is it dont run i bought a new glow plug and now it starts but cuts out after 30 seconds or if i give it a bit of throtle. Ive came to the conclusion that it need to be tuned but dont know how please help me i was hopeing to fly today as it is my day off work.
