RE: YS 63 Lost my Muffler is it OK to fly on my Sledge?
Dave in YS support says it will not hurt the engine but may suffer some performance due to the engine liking some backpressure from the muffler.
Note I said engine not Fuel tank :-).
Thanks, for all your replys and I will Clean with alchol and use RED locktight NEXT TIME!
Thanks, Dennis
