Pre stretching cable/ Prop differences
Good point, Hanger Rat; IF the cables were of the same constitution as fishing leaders, whatever.
This intrigues me. While I'm certainly not new to the hobby, I AM new to big planes; just started assembling a H9 1/4 scale CAP. I've used plenty of closed-loop control systems on helicopters, but all with pushrods and ball links.
This kit comes with a cable pull-pull for the rudder; a first for me. The airplane will weigh around 13 pounds, and no doubt there will be a lot of stress on those cables. We know for a fact that metal has a certain degree of elasticity; usually more in shear than compression/tension, but it's there nonetheless. The question is, will it stretch enough to be noticeable?
Blackie's last post regarding his airplane would seem to indicate that it does.
I would be interested to hear any other thoughts on this.
