I owned that combo and it was perfet power for the plane. I did nothing to the firewall to make it stronger and it worked out just finr. I did hav to add 3 oz. to the tail but that was no big deal and the plane never has any tip stall until I wanted it to. The only down side to this beauty is the canopy...very week and care must be taken not to crumple it while handling it. I there that that I was very pleasd with the fit and finish and could not have asked for a better looking nor flying plane. It is a bit short coupled but the right hands and setup right basic 3D was fairly easy.
