Following discussions with John at Roaming Robots, I can confirm that he is happy for a robot (preferably a featherweight) fitted with 2.4Ghz to be tested at his events.
Im prepared to take the chance and put one of these into a simple 2WD feather that Im curently building for Tanja, so hopefully we will soon know if this thing is as clever as it claims to be and does What it says on the tin!
