i have a nice clean ss8 tx that i got to have radio south morph into a single stick 9z for me, they used to morph 8u radios into single stick as well, so ya might wana try them for morphing the 9c.
if ya have no luck elsewhere finding a suitable gimble, i could probably be talked into selling the ss8 i have.
and rs2k, 2 stick radios have been around longer than single stick, CY made a concious decision to fly single back then, like a lot of the rest of us, as it is a lot more intuitive.
