RE: 3D Foamy
I respect your answer and your integrity, I was unsure as their tends to be many trolls on these boards.
I used Robart hinges on my control surfaces and so far so good. The spar trough was really not that difficult to make, just score it with a new razor blade and scrape it out with the carbon fiber spar. Just take your time. Also be careful not to go too deep. I believe it is better to have some of the spar 'sticking out' of the bottom of the wing than to go through the top. I agree there are a few tricky parts on the assembly, but that is to be expected of any kit out there. I have built everything from static plastic models to R/C submarines and have learned to 'enjoy' the tricks.
