If you notice the servos moving on the foam tape that indicates there is friction or restricted movement. Check the surface hinges for limited travel and check the controls for friction. Basically you should be able to unmount the pushrod and reach in with your fingers and move the controls at least as far as the servo does with extremely little resistance. Try to hold the end of the pushrod very close to where it sits when on the servo so you sense any binding that the servo will see.
As for me I'm a traditionalist. Grommets and screws forever..
bruce is right encan...did you tape the bottom of the servo to the floor of the fuse???when i put mine in the fuse,i stick it to the side and the bottom of the fuse at the same time...that way two surfaces are beening held by the tape...it helps to keep the wiggle of the servo down if it binds up...
