Diamond Dust replacement
you can get a short kit by.. erm.. sommit cubed?? E-cubed?? forget, but its just ribs really, i built from plan.
the engine is meant to be on its side so its streamline with the wing.
you might want to enlarge slightly if going for a 53, my 36 is mad enough. dun wanna increase that wing loading too much.
Like i said theres a chat about the Outlaw further back in this forum, have a look. theres a movie on my site too of back flips it does. theres a few movies on the net of diffrent hings it does, do a RCU search
