The Chipset is same as Spectrum, so standard Devo should technically be able to do it.
Too my knoledge "nobody yet" did reverse engineer Sanwa/Airtronics. I did not find any DIY threads on it. Many people will be happy if it could happen.
I think that Deviation would outperform with better response time, RDS 8000 first generates PPM which is then send to the internal 2.4ghz module.
On request I am able to post images of the 2.4module and receiver pcb.
