Nobody is exactly sure, but it seems to be mostly from side loads
from taxiing, as it shows up earlier when operating in snow or mud.
Some have noted that the tail section moves around quite a bit when
taxiing on amphibs, as well ....
If you're that far along, go ahead & fly, but keep an eye on
it - you will have to rip the old FUS-30 off & replace it & double
it later .... First you will notice dents near, and parallel
to, the vertical tailpost - these quickly turn into cracks.
Using a composite tail spring will help, but if you have that
solid chunk of aluminum, you can machine it down
to taper from the clamped section to the tailwheel, so it is
about 1/2 the thickness at the tailwheel - that will at least
give some bounce, but not much help with twist ! :-)

G,day chaps
Sorry to harp on the tailwrap again..........
What causes the cracks
Landing /taxying or general flexing of tailpost whilst flying ........or
have i missed something.
Will send some pics later of my Rotec Rebel..
