yes I recognised Irvine spinner...

I am not convinced about a dubro mount.... make sure that engine is properly run in before puting it in the model...

sorry if I missed the posts but what exhaust syst you going for ?

Given (I assume) you are going profilm white everywhere - I suggest a simple scheme over the top - white is heavy !

I think 9402 is not enough on the rudder but id DOES depend on what you plan to do with it ! 8511 for me is just enough ! that is one huge surface when you got the power on !
