Bob, your article is very informative, thanks!!!!!!

The precision i am looking for is not as critical as in a pattern plane, it's for a scale Reno- Racer. However, it would be nice to have as close to identical surface control as possible. The mechanical aspect is well explained in your article, but the centering of the servos itself leaves me with some unanswered questions.

Could you elaborate on the JR gizmo think please? (and maybe a link to the gizmo in question in a online shop?)

thanks for your help,
Vasek
