Welcome to the RCU forums, Ron.

I suggest discussing the use or not of this plane with your future instructor.

A traditional trainer may be more suitable for a re-start; at least during the first weeks.

Regarding the incidence, I would leave as is until the first test flights prove otherwise.

May be your instructor feels uncomfortable test flying and trimming your modified design for you.
If you try doing it yourself, you may damage the plane.

Best luck in your re-training.
