Aileron Improvements

Jim Agnew made some modifications he says improved the rigidity and remove any slop from his ailerons.

Jim's Instructions

I can't send you pictures since the universal joints are inside the wing.

All you have to do is purchase the proper size universal joints that will fit the inside diameter of the aileron connecting piece and the torque tube.

See the parts at http://www.aircraftspruce.com/catalog/appages/ujoints.php

You will have to shorten the torque tube to make up for the additional length that the universal joint adds. remember that the inside diameter of the aileron connecting piece and the and the torque tube have to be the same.

I can explain exactly what is wrong with the aluminum tubes. They do not rotate around the center line of >the ailerons. The tubes warp absorbing the torque. Proven by several Torsional vibration specialists at my request. I replaced all of the aluminum torque tubes with the same size and thickness stainless steel tubes >and added universal joints to the aileron connection to minimize the warping tendency.

When Sam DaSilva & I discovered that you could hold the back edge of the aileron with your thumb & >forefinger and move the stick FULL THROW RIGHT & LEFT without the aileron moving that made me look for the problem.
