The solution to the hinge gap, at least an easy solution, is dont use the supplied hinges ! Use the cyano type, especially the ones coming from Island Hobbies. (about a month).

Horn plate for aileron.

I will use MK Horns, and see no alternative to either
1) Move the servo about 10mm inboard or
2) cut the film, attach a wider horn plate to the aileron and re film.

The MK Rudder horns DO fit on the aileron, but the geometry is still wrong.

I will do one of these above two I imagine whichever works easiest. I know its a faff but one a model of this calibre *and cost( its not worth cutting corners in my opinion.)

U/c reinforce? My thoughts;
1) Get a carbon or GRP one to replace the rather thin alu one.
2) Carbon toes in the fuz
3) Ditch the spats and put big soft wheels on it.!! (tee hee)
4) Do greasers every time you land (tee hee again !)
