Ok...I'm throwing this out there for discussion because I just can't find a whole ton of info on this subject.
I plan on using 3/4" 17-4 precipitation hardened stainless steel rod for a tailwheel spring. I see some of these units of varying sizes, such as on the Model 12 that is 1" at the airframe, tapering to 3/4" at the tailwheel.
The Skybolt appears to use a 1/2" (?) rod...
WHat is the purpose of the taper?? Is it for spring progression?
By my calcs, the 3/4" should be stout enough but not to stout.....based on 95lbs on the tail at rest, and about 350 with pilot and passenger...
I need input and ideas here please....
