You have done a lovely job of building the Calypso,but I want to agree with Atlanta 60. There is no place for Nyrods in a pattern ship. Nyrods have there place in r/c, but to try to get any kind of sturdy control on the elevator you need to build a forked pushrod from a carbon fiber arrow shaft and music wire.
I am afraid if you fly it enough it will flutter pulling out of a loop or split s. If it does hold together you will not be achieving the accuracy in the controls we expect from our pattern ships.
Just a friendly observation and in no way a derogatory remark. After all you are flying a collectors item .
