From this ebay seller:
There are a few folks selling them on ebay and also on aliexpress etc, but with the 18x metal geared servos, lower bearings and alloy horns this was an OK deal. There are some sellers doing full kits cheaper with poor feedback or in the case of Aliexpress no feedback.
I’ve had a look through the kit bits now, although I should be working and it’s a bit of a jigsaw puzzle as there are no instructions but the hardware part of it will be the least of my problems I suspect. :-)
FYI, It appears to be a pretty much direct knock-off of the lynx-motion alloy hex.
Cheers, Chris H.

Servo power will be a couple of 10A switching regulators for the servos fed from a 3cell 1800maH Lipo. Probably a separate small 2cell lipo to run the micro, will see on that count although it’ll run tethered initially as I don’t have the ubecs yet, and even though the servos are metal geared I’ll just make smoke if I try to have it wandering around by itself before it’s debugged. :-)
