Default Tailspring

Hello all! Just received a flat tail spring through from Steen for my Pitts S1S project. They’ve sent a Citabria spring which is slightly annoying as it is a different style to the type specified on the Aviat drawings. Has anyone used one of these or experienced the same issue. As the upper leaf doesn’t go all the way through it would have to have some sort of shim where it bolts to the fuselage to keep the angle. I’m considering sending it back and re ordering one from Aviat but thought I’d get some advice on here first in case this is normal practice.

Cheers,

Andy

Remember Steen sells homebuilt S1-C and their version of S wings; Aviat sells only Certified S1-S parts. Homebuilt, do anything you want, vs Certified has to be per drawings. Really two different versions of the same plane if you want to be picky. The question comes down is yours homebuilt and have the homebuilt fever or is it Certified and has to conform?

Default Spring

I think a Piper J3 spring from Wag Aero is what you need. Wag should be significantly cheaper than Aviat. Years ago I remember someone breaking a tailspring at Fondy and we got a replacement from the ag operation west of Fondy that was a perfect fit.

I didn't find a cheaper tailspring when I was looking during my shimmy aftermath. Everyone was charging $150-175 for the correct Aeronca-shaped spring (which is similar to all the other springs for similar planes).

For homebuilts, if you have an original spring, you can take it to a truck spring manufacturer and they can make a new one for you for about $30. Some folks have been known to use them on factory built airplanes too.
