Guys, one thing I'm confused about, I have done load testing on most the best that servo manufacturers have to offer, including JR 8411's and 8611's. I loaded an 8611 up with 15 anda half pounds of water in a pitcher one inch off the center of the spline and it jerked that pitcher around like the servo was hardly working.

I can't imagine a linkage being so out of wack that you'd be able to hold an 8611 down or move it back with your finger. I would try another 8611 or stick an 8411 in there and see if there is an immediate change with your finger pressure on the control surface.

Or can someone explain to me in words I can understand how the geometry is working so in favor of the control surface as to stall one of the most powerful servos on the market.
