cutaway,

I would balance the plane so it is manageable. The elusive 5' radius is something to shoot for, but don't sacrifice handling. It was put in the pattern in 1957 and, as far as I know, has never been achieved. It has to be performed in milliseconds and still straighten out at 90 degrees.

I just noticed that in a previous thread you were going to try draggy or heavier lines to keep the nose from goind out. I would suggest going for .015x60' and adjusting something else. Make sure you have no rudder offset or engine out-thrust first.

I assume you did not make provisions for adjustable leadouts.

Edit: Upon rechecking your pics, I guess you could not move the leadouts forward. If you make design changes, try the wings ~1" forward.
