Thanks Barry & Barry. Inverted it is then. Should help the lateral balance too. I'll probably be using a 17x4w or 16.5x5. I've used the 17.x4w on my funtana 90 & it's great. Haven't tried the 16.5x5 though. 16x6 flew it a little to fast for my style. May be a different story on this plane though. Thanks for the tip on right thrust, I'll probably go ahead and add it. My other .90 size planes have needed it as well.
