Switched over to a Futaba T8 and very happy, got my gimbal working great too with it Question though, I did the IMU calibration a couple of times but I still have a lazy drift going on in GPS mode. Is it appropriate to use the trim to correct drift now I have them?? Or should I be chasing down other problems causing drift? Dumb question, how do I calibrate the GPS? Whilst using the Nazza utility it's giving me a warning saying it needs to be calibrated. Wow, when I read that back I guess I got my own answer hahahaha. But outside the GPS is fully locked, no Red LEDs, so surely that means the GPS is working..... I never calibrated a GPS unit before, it just locks to satellites and boom......?
