            Originally developed to address a flutter issue on the 3.1 super extra (no longer a problem) this kit was also found to be a great upgrade to any Composite-ARF that uses a brass / aluminum hinge pin.

            Sheet metal style self retaining bushings are inserted into the phenolic hinge plates in the Stabilizer and Vertical fin (this requires drilling with a special drill provided in the kit).

            The hinge pin is replaced with a Stainless Steel tube and this is perhaps the most valuable part of the upgrade kit.  The brass rudder tube over time has shown a tendency to deform slightly, especially if the phenolic has started to wear.  The stainless steel tube will never bend or deform in use and will last the life of the model.  The Stainless Steel tube is also the preferred material to work in conjunction with the bearings in the kit.

            Additionally, we have come up with a unique method of retaining the hinge assembly.  One end of the tube has a socket head and cap screw and washer fixed to it while the opposite end has a threaded rod protruding from it.  Now you can insert the pin, hold one end with a 3mm Allen wrench and a washer and a nyloc nut fixes the pin in the completed assembly.  This has the advantage of allowing disassembly of the control surfaces at any time.

                We have just added the "Bearing Only" Kit.  It consists of 15 bearings and the correct drill bit to enlarge the bearing holes with.
