Scrap all them torque rods and put dual aileron servos in. One in each wing half.

I know its a lot of work, and a bit extreme, but you won't ever have flutter problems again.

Here's how I make linkages:

Get a 2-56 or 4-40 rod thats threaded on one end only. Buy a tap and die for that size rod. Get some Sullivan clevis' for the rod your using.

Now, install the horns and put a clevis on the threaded end of the rod. Install the clevis and rod assembly on the servo horn. Next, put your other clevis on the control horn. You can now "eyeball" the length of rod that you'll need for the complete linkage setup. Cut the rod off at the right length with a pair of sidecutter pliers. Use your die too cut threads on the rod and assemble the whole unit for a slop free linkage. Make sure that you use back-up nuts on the rods and run the nuts down onto the clevis. USE LOCTITE!!!!!!!!!! on the threads. The nut keeps the assembly from rotating and coming out of one of your clevis'.

I've seen this setup work flawlessly on many planes. The only time you'll have problems with it is if they get too long and start too flex- or: if you don't use LOCTITE on the nuts.

I hate torquerods. They are always sloppy and they don't last long before they rip out of the wood. Those torque rods on the ARF are great for flaps- if you don't need the flaps all the time, but for ailerons- where you use them almost constantly- they suck.

Hope this helps
