Good thought, Muzzer, although it's slightly more awkward than that. There isn't any documentation as such, it's just an applicaiton that is all in Chinese. You can guess a couple of the usual menu items based on position, and I did find one entry that gave me a COM port prompt, but that's as far as it goes! I'll need to look at whether I can extract the symbols from the app itself and translate those. It sounds like Chaz, Dean and I are all in roughly the same position - controller and servos/drivers all set up on the bench (or coffee table, in my case) so not in a position to actually do any tuning at the moment. So fingers crossed that a translated version will turn up before we actually need it!
