As luck would have it …
A pal upgraded his Android game pad and gave me his superceded toy.
Turns out it’s a JXD S5110. No bluetooth but has wifi and gamepad buttons so a wild addition as it can act as a remote console/controller talking to either the Gumstx Killer or any of the Android phones I am using as roving camera/brains.
Although, I guess the temptation will also be to use it for control of the AR-Drone (trawling Internet to find out to get access to the buttons).
