I disagree completely. The bushing at the tail will maintain the pushrod shaft through any high G maneuver, as is it's intended purpose. Remove the pushrod bushing at the tail, and this will allow for flex.

I have always used the method without the bushing. Honestly, I do not fly well enough to tell if there is actually any flex or not. The engineering is sound, regarding the bushing method.

I do not have any doubts this bushing method is foolproof- so long as it gets properly installed.

And if I am wrong, then it is my price I am willing to pay.
