Pushrods..
My RV6 plans show the F-665 pushrod on dwg 41.
F665 - 17.5 inches end to end into which you then thread the heim M3414 rod end bearings. The distance to the end to end midline of the heim bearing openings once threaded in place is 19.0 inches. It is 1/2 " hex 6061-T6 and you drill #3 1.25 inches deep and tap 1/4x28, 1 inch deep both ends.
F-690 Elevator control tube on dwg 34. 1.5 inch diameter, .035 thick 6061-T6 , 78.0 inches long end to end to which you then add the VA101 end caps and heim MD3616M bearings to each end. This is from the bellcrank to the back.
F-689 is the elevator push rod from the control stick to the bell crank. It is 3/4" .058" thick 6061 T6, 47.5 inches long end to end. It takes the VA115 threaded ends that get riveted in place with MD42BS pop rivets and then the heim 3514M bearings get threaded on.
Hope that helps..
