Ok so I just got my first nitro rc. I did the break in procedure I watched videos plus did as the manual said. I got it tuned up a little i had it running Ok I had kept it kinda rich just to be sure not to screw my engine up. So now for my issue is I can't seem to lean it out without it going crazy high with rpm and its spitting so much gas out the pipe I run through a tank in 5 mins an its seeming to have poor acceleration. The only thing I can do to drop the rpm an lean it is to turn my trim knob to my throttle all the way down but then it has hardly any break . Can anyone tell me wat I may be doing wrong?
