As noted above is it possible to buddy my Royal Pro 9 to a Hitec Aurora 9, anybody done this?

Hi, Frank!

I think it is basically possible - but not wireless! What you need is a custom teache-studen-lead. There are some circuits on the net showing pin assignments and what else is neede. I stored them somwhere on my PC but can't find them at the moment.

with regards
