RE: About Your RC Simulator
You bet.
I purchased an adapter cable for my Walkera a couple of years ago.
the PIC adapter was $40.00 and then the converter cable for the Walkera was an additional $25.00.
You can also make your own, but this requires a (very) simple circuit... but even then by the time you've obtained the interface plugs, components, etc. you'll end up paying far more than the Nitroplanes E-Sky USB Interface.

We got four of these earlier this year and used them to teach students in our RC Flying "summer camp".
They worked great!
