RE: Seagull's
Matt
I use CA hinges in everything and never had any issues with them, but I never use the thin crappy ones that come with most arf's.
The Great Planes bulk ca hinge material with 2 x 2"x9" sheets is way thicker and makes lots of hinges.
Pinned hinges are really not required on this airframe but sealing the gap is a good idea, although mine really hammers and flies fast, I have not sealed the gaps.
I used the original landing gear and put 3" mains and 2 1/2" nose wheel and beefed up the firewall by adding another thickness of ply and also another small piece of ply where the nose bracket bolts on and its really strong.
No onboard glow fitted.
Never had any issues with the wing incidence just bolted it on and ca'd the ply reinforcing washers in place.
CG is set between 100-105mm and its easy to land with heaps of elevator authority.
All round a really good cheap well made plane.
Goodluck with DA no.2
Cheers
