Hi

Just a note.

I began to link up my elevators with the CMP hardware. After a minor stress test on the CMP linkage to elevators, as i suspected with this type of connection, the configuration yields a lot of play.

The arrow shaft is very thin walled and not stiff, mine already split at one end.. Clevises already snapped as i tried to connect one to the horn. The "Y" connection is ok on short wire spans, but here for me, not good.

Do your own test and see if this is a real concern.

Imagine the loads with the large engines and a aprox 13-14lbs model.

I am going use a carbon rod to an internal linkage joining the 2 elevators, with the carbon rod pushing on center of the elevator load via an internal arm. No flex, no play.

Or i may use the CMP arrow shaft with a wood dowel that I can epoxy into it for additional stiffness making the hollow shaft solid instead of using up my carbon rods..
