Hi Richard, If we're both including the same stuff, you've come in about 50 lbs below the weight of mine with the stock housings, and the Autoflight drive. That's pretty amazing! Have you moved it to a test stand that will allow a real prop yet? I'm dying to see if you have the same torque reversal resonance problems. I hope not, but I don't know how you won't, unless the coupler in the Hirth drive is that much different. I've just ordered a softer coupler for the Autoflight drive, and will see if that helps.
