RE: nylon hinges
If this is only your first few airplanes and you have no experiance otherwise and only reacting to hearsay on the forums then you I suggest you actually give them a try. They work and they work well and they are most ideal on trainers and typical sport airplanes. I have used them for years in a wide variety of aircraft and will continure to do so, not every one but most.
Tyically when inspecting new airplanes for folks the most frequent botched hinging jobs are done by folks who just had to change out hinge types for their first airplanes because they thought they knew better.
