Hi james - that's a nice Attila you have there-I think that I saw that come up on eBay, To answer your first question, it;s quite normal for the little OS .26 4 stoke to have very little apparent compression, when compared to the two strokes that you have been more used to. The model will fly beautifully on that motor and you will have loads of fun with it. Mine had an ancient OS .20 FS which ran like a little sewing machine - I used to use an electric starter to get her going at first, but she would start with a flick when warmed up a little. If the model were mine, and I was unsure about the fuel proofing, I think I'd follow the advice that they guys are giving, to take the motor out an bench run it to get familiar with the controls, whilst taking the opportunity to add a coat of protection to the engine bay. I won't venture any further IC advice, since I'm no longer a practicing four stroker. Best of luck with the model and enjoy those lovely chandelles and Immelman turns.
