Dave Trible & Ty Marcucci, I am working with an ARF so all the construction is already done, and the model is covered in Iron Paint (iron on film), so it would take quite a bit of work to add another cheek doubler.
Today I made a 3/32" triangle and joined the wing L/E to the fuse in hopes that this will help.
Paul Taylor I also remember that problem about APC hubs being out of "kilter" so I plan to check that also.
Being that this is a one cylinder engine I can balance the prop, but that doesn't mean that it won't "shake".
I thank every one for their suggestions/advice, as always this forum has fellow's that like to help, that is what makes being a modeler so much fun..Again I can't say thanks loud enough...
