Jeff, #24 says to cut 61/2" long rod threaded on one end. #27 says on the non threaded end, the end opposite of the threads make a 90 degree bend 1/4 " long. This is the end that goes into the wood push rod. Here is what #27 in my manual states: On the non-threaded end of the 6-1/2" [165mm] wire make a 90 degree bend 1/4" [6mm] from the end of the wire. I hope this helps. One thing I would like to mention is the CG on this plane. IT IS CRITICAL. This plane sits on the CG like a round rock on a pencil point. On landings she wants to nose over.

Good Luck

Bob
