Wow.... thanks Ion. I think I got what you're trying to point out for the most part. Some of it was a little over my head, but very informative.
I've tried moving the CG in the past, but I think I did it a little too much. It was pretty uncontrollable. But I'll try it again as soon as I get the plane back up and running.

If that doesn't help, I'll try the 12x4.5 prop. It might be a while till I work on it. Between school and work, I'll have to make time for it.
I'll give you guys an update as soon as I try it.
Thanks again.

Mark
