Some concern was expressed at Mentone about the stability of the rudders on my new design due to the large counter balance. So I decided to make a simple 1/4 scale test rig to magnetically stick down to the hood of my car. After the rig blew off the first run (?!@%!$%), I duct taped the repaired unit on and proceeded to test the model at 60 mph down the runway. There was no instability or flutter at all, in spite of the model being made of rather flimsy cardboard. The model is 100% statically balanced at the hinge point with pennies and has approximately 25% of the rudder area ahead of the hinge line. The gas to drive up and down the runway probably cost more than the model test rig. If there is still concern, I may mount the whole tail on the front of the car.
