The wing joiner is very, very loose... Anyone else have this problem? Just eyeballing the fit the joiner is 1/16 too small on the sides... and about 1/8 two small on top and bottom..... the length is perfect... That's the only joiner in the box...

This was mentioned before in another thread. I think two or three comments made about it. The solution was to add a bit of hard balsa and then sand it to fit. Waiting for mine to come, have been reading the threads - seems to be the only problem of note that I have read. Hey... good luck

All I did was just fill her up with 30 minute epoxy and all is fine. Just wipe the excess with a paper towel and alcohol. I have a saito 100 up front and she holds up fine under high stress g-maneuvers.

mine was fine, just needed a bit of sanding. Have a 46fx on it for now.
