I'm setting up the elevon system in my F22. I'm using the JR 8411 sevo. I noticed that when the system is hooked up I get about 1/8 slop at the trailing edge of the elevon. Is this OK? This is the same setup as the f15 from Avonds.

I traced the slop to the servos. What can I do now? Please see picture for my set up. Are there other servos that may be betwr suited for this application that give at least 120 in-oz?

Thanks
