While this damper didn't work out as planned, there are still other solutions I could try, and I'm sure it's possible to make this work.   Unfortunately, I've already spent almost 3 years (time flies) messing with this, and there's just no escaping the fact that it's going to be too heavy to be a 912S replacement.  Until someone manufactures a better 100 HP rotary solution (two rotor I hope), that they are actually willing to sell for aircraft use, I'm afraid the 100 HP rotary isn't going to be much of an option.  The 912S so desperately needs competition...
