RE: TT 53 Redline leaning out
Good day
Pulled the motors out the new 50 SE and the 50 V2 last night. after checking all bolt were still secure, I noticed that the new motor had the "hidden" needle turned in to far causing the mixture screw to be 1 1/2 turns to far "lean" when adjusted to factory specs. Set needles the same as old 53 Redline. will test this weekend and give feedback. I think that what was happening is that the needle valve was set so rich that when you have started the motor it is running only on the low needle, which it still uses in a hover. after going past low into high side while flying it doesn't transition evenly back to low. the further I came back on throttle it just caused the mixture screw to close further, getting leaner all the time. must learn to flick the switch and "auto's" anyway, I hope this is what it was but will have to test it out.
Cheers
