I didn't have the wing dowel problem,but I did experience the others.For the nyrod exits,I just fingered a drill bit at the end and it worked fine,I was able to get the antnna out the end with a little patience.As for easy to fly,my seven year old son who just started flying solo this summer flies and lands it with no problem.Mine/his has a OS 91FS,great combo.This is an excellent kit,quality is great.You won't be sorry.
BTW the antenna tube runs along the floor of the fuse.
