Walton,

1-3/4" standoffs with 1/4-20 on both sides from Roger. They look and work great. I recommend the red!

With Hitec 605's on the elevator and one 645 on the rudder in the stock location. 2700 6volt at the rear of the canopy and receiver and throttle servo on the servo tray and tank mounted on the wing tube I am 1/8" in front of the center of the wing tube.

I need the least amount of down elevator to maintain inverted flight and have 9/16" throw on low rates elevator for a fairly tight loop with no hint of snapping. Stalls are straight ahead and that was before I laterally balanced her.

Let us know how yours comes out.
