<p style="margin-bottom: 0in">Hi
Ive done the hinge replacement thing a few times. I usually cut all the hinges off with a dremell cutoff wheel and then i just use a drill bit in the dremell. i don't push to hard on the bit and i let the plastic heat up the drill bit follows the plastic and makes a nice whole for me to glue in a new hinge. In the past when i see a hinge worn out i look for other issues causing it like prop balance the need for support wires to aid in the vibrations from the engineand the the #1 cause Ive found is linkage geometry. there has to be a little give someplace. For example here is a linkage that destroyed rudder hinges faster than any other. There was no give at all here when i replaced the solid linkages with wire ones the problem went away.</p>
