RE: Too much down thrust on GSP?
Richard,
Your pics are great! Close up and clear... nice.
Stupid me, I put the YS muffler on my Spit, cutting the cowl out like a termites nest. Your pitts muffler is the way to go. Good on you!
Went to the flying field to try my right and downthrust but my brand new YS 110 would not idle; even with my 31 years of RC'ing, 5 hours of help from my flying field buddys and their 100 years of cumulative engine experience..
So.. I've got a bum engine. No Joy... Here's the bird... hanger grounded.
Please post when you fly.. good luck and thanks for the pics..
