Elev. Pull pull Question

[Dean Pappas]

Hi Matt,
Rocket City, now Nelson, use 6-40 screws. This offers the better precision, and slightly more strength than even a 6-32!
The #69 series horns are very good, and I think the 69E offers a long overhang option. It's not as long as the DuBro 867, but it is often enough.

Keith, please note that 4-40's are known to snap off a control surface. It has happened to me. The break is a straight forward fatigue fracture. If 6-32's are not useful to you, consider 5-40's. Personally, I do find 6-32s do just fine in this application

Cat's Meow? Maybe not, but darn close. The only thing that keeps them from being the Cat's Meow in my book is the 6/32 threads which don't offer as precision of adjustments as 4/40 or the MK horns. 
 
Lance's suggestion of offsetting the control arm at the servo is perfectly valid also.
