We have (4) of the low wing trainers flying. Yes they did need some extra work to double check them. I used a lot of epoxy on all of the joints I could reach. I also poured some thinned epoxy where I could not reach.

They do fly very well. Mine died when the battery died and it flew 3 laps all by itself. I have been waiting for them to be in stock again so I could get another one.

As said above. Give John a PM and see what he can do.
