Which reactor are you talking about? The Reactor .46 EP/GP is one of the greatest flying planes in that size range. I truly believe someone that has mastered a trainer can easily fly the Reactor. The Reactor has gotten some bad press due to landing gear and covering issues though. The landing gear issue was corrected by GP not to long ago so I believe that is not a concern anymore. The covering has a tendancy to peel in some spots that cannot be ironed down again. That is an easy fix with some clear ultracote paint over the finish before assembly. As for durability I have not had a single structual problem from mine and it has well over a 100 flights on it. I have had somehard landings and broke carbon fiber gear in the process. Not the plane though. This plane is very much worth considering. I forget the little problems with it when it gets in the air!
