Ive glued a slat from the other kit in my stash to the left wing.But i managed to damage it removing it from the sprue!. So ive put a bit of filler on it. The inserts for the guns on the wing leading edge needed a bit of filler as they dont fit too good. This kits ok. But its not as good as the Tamiya 109E i built years ago. I only really got this kit for the decal sheet. Maybe it doesnt seem that good because im also building the superb new Tamiya 1/32 Mosquito.
