Default RE: Should I have not flown?


ORIGINAL: MinnFlyer

First of all, no hinge will offer more total range than a CA hinge. The range of the hinge will depend on how sharp the bevel is and whether or not the TE of the wing is beveled. It will also be determined by the size of the gap.

All you have to do is:

Install the hinges and close the gap. Now, before adding the CA, move the surface both ways MORE THAT IT WILL MOVE IN FLIGHT. This will open the gap. DO NOT CLOSE IT AGAIN! If the gap is more than you can live with, re-bevel the surfaces. If the gap is good (about 1/32 - 1/16 inch) add the Thin CA.

Second, while a CA hinge might seem a little stiff at first, just remember that when you are flying at 60+ MPH, there is a LOT more air resistance holding that control surface than a CA hinge could ever compete with. in other words, it's not worth worrying about.

And finally, if the surface is very difficult to move, you probably do not have enough gap (Which is the biggest reason CA Hinges fail) using a different type of hinge will not fix this. If the beveled LE of the aileron is hitting the TE of the wing, that will limit the movement of any hinge.
You are correct, I made the gap to small on the alierons. I did better on the tail and it did move better.
