After close to 400 genuine flight hours over 5 years, and numerous patches, my Boomerang 40 trainer finally destroyed itself. Despite all the pre-flight ground and range checks the aileron servo failed on take off. The RX is damaged so it's hard to tell what the cause was beyond the aileron servo didn't respond.
I've threatened the club to rebuild it. I can salvage half the fuse (rear half) and graft it onto a donated (but used) fuselage. One of our other members is sure to have a spare wing, he's crashed about a dozen Boomerangs.....
As long as it's got more than 10% original parts in it I'll call it a restoration....
