The thick tail spring is NOT the problem ! The cracking has been
found with ALL kinds of springs, since 'way before the current thick one
was supplied. Sorry, but you will have to do the doubler ! :-(
i think the current one will work fine if you grind in a taper in
thickness, from full, at the top, to about 1/2 the thickness at the
tailwheel end. This should allow some give.
I don't like steel springs (prefer composite) because steel bounces
toooooo much, adding loads, AND snaps off at inconvenient times. Just
my experience with Super Cubs and Citabrias doing 6 - 10 landings an hour
towing gliders..... we replaced tail springs once or twice a season.
I have used fiberglass tail springs on all of our Rebels, including
Number 001 - never had one fail catastrophically. A couple delaminated -
a gentle let down, easily patched with clamps to get home. YMMD ! ;-)

Can anyone tell me why ? they ( mam ) is using such a large tail spring? I
don't see any reason that a spring off a luscombe or other small
taildragger wouldn't work.
Are there any other ideas out there ? I saw the trailer spring in the
archives, and that seems to be the only tail spring system that I saw in
there.
I think that is whats causing all the cracking in the fus 30 ?
Thanks
