The repairs to the extra turned out pretty well. The motor mount was reinforced with a few pieces of ply and the utimate glue expanded and filled up the gaps nicely. It feels strong when i hold up the plane by the firewall and gives it a few twists here and there.Put a few drops of CA to the mounting holes before retapping them to make the screw threads last longer. I do this to all my wooden screw holes' threads.
The damage cowling was repaired with a layer of fiberglass cloth and epoxy. Sand it down and sprayed painted. Amazingly the motor fits together with the cowling better after the repair. Oh well as they always say planes flies better after repair. Back in the air for hovering training soon.
