Parts are cheap for these. If it's that much of a problem, just order a new stab.

I have the modelfly Ready II on floats. I bought the whole plane on ebay with servos, radio gear and engine all done. I figured if the guy didn't do such a great job building it and since it was plastic, I would take it apart and fix it. I was shocked when I won the bid because I stole the plane. The plane came with an OS .46 and it would just barely get the plane out of the water with a head wind. So, I weighed the plane and it weighed 8.5 pounds. I had to modify alot as the plane is only supposed to have a .46 and Modelfly doesn't sell anything to help install a bigger engine in that plane but, after modifying and installing an OS .61 FX, the plane flies great. The extra power was just the ticket. I put about 8-10 flights on it today and it was a blast to fly.

I also leave my planes about 2ozs. nose heavy and make sure that I don't under power them and since I began doing this, all of my planes have flown much better.
