Pushtube from stick to the bellcrank length - 32" 6061-T6 5/8" .058 wall tubing with AN 3 bolts. from the bellcrank to the elevator horn - 67" same materials. The bellccrank has at least 1/4" thickness of material around each drilled hole. All AN 3 bolts are drilled and cotter pinned at pivot points. The bellcrank, brackets there and at the stick are cut from 6061 T6 extruded box beam, .140" thick. Colin Rainey
Colin, Just for reference my pushrod from control stick to bellcrank is also T6-.058x.75. The one from bellcrank to elevator horns is T6-.035x1.5. Like I said, this is for reference only but it sure seems like you are in the ball park. Dana Overall 5/8" diameter Tubing over a 67" span does not sound very ballpark to me. The RV uses 1.5 " over nearly the same span. Lynn
