As the Q500 doesn't have retractable landing gear, I can't imagine they'd ship the Q500 with that controller unless they had run out of ST10+s for the last few that rolled out before they completely dropped the model.
I just picked up a second Q500 4k Typhoon Tuesday and it came with the ST12 pictured. The two extras do nothing for the Q500 4K Typhoon, they are only for the H. My previous Typhoon came with the ST10.
Hi, mine arrived brand new Typhoon Q500 4k with New ST12 Ground Station. I found the Specs online, exactly same as ST10+, So I refuse to go thru Firmware update as my Typhoon is latest version, and no Updates are needed. It flys perfectly out of box, no calibration needed. If you have another Yuneec Hex, you may link it with the ST12 also, later.
