Hi Guys, I do not think it was a bad production run problem as I bought the servos over a period of time as I bought new planes to put them in. --Just a funny thought- Maybe it is the High Altitude here in the Denver area. I just took inventory of the servos in my airplanes today to see how many High torque and/or high speed ones that I had and I have about 16 servos of those types. I do not think that it would be worth the expense to replace all of them JUST IN CASE of a future failure. Thanks for your comments, Bob
