I was just wondering, I know my 40 pretty much floats in at idle and damn near harriers right to touch down. It did take me awhile to get the idle right to slow that demon down enough to hit the run way. I cant wait to get out to fly the 150, she has about 3/4 gallon of fuel through the brand new engine so I think its time for the air now that all the tuning is good or at least it is now. I have been in the garage with it tuning so I am sure I will have to make little adjustments when it warms up a little. I have measured about 19lbs of thrust out of the big tigre on 10%, and she idles perfectly with that 4 stroke plug. I have read alot about others with ideling problems and I took it all to heart and did all the recommended things and let me say that I am really impressed with its performance on the ground so I am sure it will fly great also. I cant wait to hear your report Link about how that 3 blade prop works for you.
