Welcome Ray,
I came into this Forum with an HGFA backgound - hang gliders and nano trikes. Then when I bought my Airborne Redback I decided I'd get more value out of the RA-Aus. This in turn rekindled my interest in 3 axis, so in time I moved on to a Jabiru.
By my reckoning whilst the HGFA support trikes, their heart is still really in hang gliding. They are (or were) also more expensive to be a member of than RA-Aus, but I dont know why...
As others have said, irrespective of who issues your licence, you are more than welcome here...
BTW: Nice XT912.. The Tundra undercarriage gives you plenty of landing options!
Cheers
Chris
