Hey Guys,
I just recently built a Losi XXL from scratch and today it decided to go nuts on me. Luckily I had the chassis up on the deck railing upon starting it up because it would of been a complete run away... Anyways heres whats happening as follows. I start it up and its flawless, purring like a kitten. Then I notice the spur gear and engine clutchbell starting to chatter a small bit back and forth at the start then all 4 wheels start slowly picking up speed. Soon the engine clutch bell is full throttle and so are the wheels and it sounds as if it is wide open. Checked carb has the usual small opening as it should for a slow steady idle, slipper clutch is 1 turn out as recommended from tight. Reverse toggle on transmission is pressed fully against the tranny body as it should for forward motion. Im thinking maybe the clutch shoes might of been damaged while I was tweaking everything after it was built, because I do recall a time where the engine idle was high and my brakes were set way to tight. So being a rookie I turned down the throttle trim to b-50 on the LCD Radio which more then likely completely locked up the brakes causing strain on the clutch shoes. So do I sound like Im on the right path before I pull the engine or is it possible the tranny is somehow no good ? Thanks guys and Im sure someone has had this issue Im having now. :mad:
