TT39 Engine

I am flying a Raptor 30v2 but I have altered both needle settings to try and get it to run better but now its running like bag of nails can anyone tell me what setting should both needlels be and the best way of doing it.

Thanks

Paul

hi paul

this is a good start
fully close the carb screw in the low needle thats the one inside
the throttle arm and reopen 3 turns
high speed needle start at 2 turns out.
you should be using 15% nitro with 20% oil content and OS #8 or enya #3 plug work best.
it should have a nice smoke in hover,this is a good starting point and we can work it from there.
when flying try to notice if it quits real dry or if it sputters before stoping
