Hello, Did you ever get the sukhoi to fly good and balance out with the saito .82 ? That is the same setuo mine has and the only reason that its still alive is because it hangs from the cieling after 3 flights of hell trying to get it to come down and land like a normal plane. Dont want to wreck the new engine so i was thinking of puting a .61 or .46 that i have laying around the house. I would like to here how yours went if you dont mind.
