OK...There are three issues that we are going to try and cover here. 1) the two gaps (wingroot and wing-fold) in the wings, 2) the gear extention problem, and 3) the antenna replacement. Let's start with the worst and most common reported by people....wing gaps!
Let's look at the gap at the wing roots first. The first thing you are going to have to do is seperate the center wing section from the fuselage.
You will notice that there are four "J" hooks there that fit the four prongs attached to the fuselage. These are supposed to keep that gap out of the wing roots, but they don't work very well. Instead, look inside of the openings at the wing root and you will see a shaft about center of the wing on each side. This is what we are going to use.
I know...I know it's out of focus, but you get the idea. Measure across the opening and you should get about 90mm. Take a couple of plastic wire ties and loop them around those vertical shafts and tighten them till the measure space is about 3-5mm less than originally. The plastic ties will "give" as you re-assemble the center wing section to the fuselage. Once they pop together...VIOLA...no more gap at the wing root....and the ties are hidden under the cockpit floor where they cannot be seen. If there still is a gap, pull the fuselage and wing center back apart and tighten slightly and check again. Make sure the ties are looped around the top of those shafts closest to the inside of the upper wing surface and you should be good.
OK...no the wing fold gap. Alot of the gap is removed when the square post is snapped completely into the wing properly. If you look at the underside of the hinge with the wing folded and attached, the silver pin should disappear almost completely inside the wing. If it doesn't, put your thumb on the hinge and press directly in to the wing. It may pop back out a little when you try un-folding the wing and lining everything up, so be persistant! You should end up with this kind of wing profile when you are done....no glue or mess!
Now for the landing gear. Some people (me included) have had problems with the landing gear refusing to snap completely forward once the wings are assembled. Easy fix! Pull the wing outer panel off and look inside...this is what you will see.
Notice that the top-forward part of the landing gear door is resting on part of the ridges that wing square beam snaps into. So...all I did was sand the corner of that wing fold tube thingy until the gear snapped past the edge all the way down.
Lastly the antenna. Cut that darn thick thread off and throw it away! It's ugy and not very accurate. Go to any local craft shop and look for the spools of copperwire (really thin stuff, but strong) coated with paint that is flexible. This stuff is great. I make coils out of it and replica small springs. Cheap, easy to manipulate, you can cut it, glue it, solder it....what's not to like?
