RE: nylon hinges
Well, the hinges that came with my Venus II and my Excelleron 90 are CA hinges. And, those are pattern type aerobatic aircraft. And, both planes still fly and fly great.
If properly installed, (as with just about anything else), CA hinges will be just fine in that aircraft, or pretty much any other aircraft you fly.
Many serious aerobatic pilots have been using CA hinges in everything they fly with absolutely no apprehension. And these guys spend a lot of money on their aircraft, much more than I have spent, that's for sure, and have complete confidence in them.
