hey thanks don, i also have a fuel t and only 2 lines entering a tank. alright as for adjusting the engine... i worked on it for about an hour i got is to where by sound, and the way it was running i had it. but when i held the plane vertical it would run for about 15 sec or less then stall out. now my judgment say its probly still to lean. what do you think. Also right now im running 15% nitro 16% oil mix. its what my local hobby shop said i sould use, but i dont really trust them. whats the best % fuel i should use for the saito 72? thank you very much! Dave.
