Exactly. I have done the same thing with guys.

I used to offer a deal to guys in my club years ago.

I told them I would give them (4) 8411 servos if they would put them in their model and fly them. Then all I asked is for them to be truly honest and tell me if the model was now trimable and could fly the entire length of the field with no input, no hunting, etc.. If they did this and agred there was a difference they had to pay for the servos. If they did and thought there was no difference I would take them to dinner and they had to give the servos back. I never took anyone to dinner!

The average guy would tell me he could not tell the difference until he had them in his model. My comparison was if you had to drive a Chevy Capri through a slalom course to the grocery store and then a Chevy Z06 Vette could they tell the difference or did they have to be Mario Andretti to tell. Most would agree they would be able to feel the difference. End result is the other serovs are great servos. They work very well and don't fail. Absolutely nothing wrong with that. If you wish to step up in performance, you routinely have to pay more and get what you pay for. Some things in life are the same regardless of the situation.

Fenderbean, like I said show me the pictures of your setup. If you have that kind of slop there is a geometery issue or slop in the clevis pins etc. I would be happy to look and help. If not, no biggy. Just trying to help out a fellow new jet pilot.
