Hey peoples,
I am currently building my new CMPro Extra 300 90, and am in the process of doing the CA hinges.. the only thing i am worried about is there is only 3 hinges per aileron.. is this enough? Also the hinges supplied are a thickish/stiffish round hinge, so i bought some great planes hinges, but they seem to be a bit smaller and more flexible, which should i use?
Thanks, james.

I use the nylon hinges with the pins. Also, don't be afraid to add more hinges. I would NOT use the CA hinges as hinges, I use the ca hinges to apply epoxy into my hinge slots prior to inserting the nylon style hinges.
