The users manual updated by @ogrench , https://yuneecpilots.com/attachments/typhoon_h_plus_manual2-pdf.10287/ on page 42 for compass calibration has the following warning:Should the camera be removed while doing those calibrations?
@NorWiscPilot , Good points, I have NOT done a compass (or gimblal, or accelerometer) calibration yet so forgot that the H+ must be ON, hence having the gimbal locked is a VERY BAD IDEA. (I'll modify my post after I finish this one).It all depends on whether the calibrations can be performed with the camera detached.
Not sure about the H+ as I do not have one nor have I read the manual.
If the calibrations, aside from the gimbal, can be done without the camera (as in, the H+ can be bound to the ST16s without the camera and the calibration menus are active without said camera) then by all means save the wear and tear in the gimbal. But, if leaving the camera on the craft, it is likely a good idea to leave the gimbal lock OFF whenever powering up the H+. The gimbal is going to try and keep itself level no matter what attitude. Therefore, the lock will likely only hurt, not help.
That’s what logic tells me anyway. “Your mileage may vary.”
P.S. my point of reference is the H520. I have yet to find a way to calibrate anything without the camera attached.
I can confirm that the accelerometer calibration does indeed work with the 'Start First' method. For me, the calibration I enjoyed the most was the Gyro calibration . Almost no anxiety expended while that was being performed .For what it is worth, I have found that to do the Compass calibration on the H Plus without camera is possible - you just need to start the process first - then remove the camera and proceed. As yet I have done it three times and have not run up against a time-out like can happen with the 480. As for the accelerometer calibration; I did not figure out the "Start First" method mentioned above and went through it the first time - gimbal attached. I was cringing the whole way. Since my Plus is working perfectly so far (knock on wood) I have not attempted a re-cal of the accelerometer to see if starting the process first will work with the camera removed but I have a feeling it will. My little canary wings are a tad sore at this point.
@Ty Pilot I'm now having second thoughts about the accelerometer calibration because the 'revised manual' states that the the controller display will change with numbers being shown for successful calibrations in the various orientations. My H+ did the double beeps in each orientation and when done the lights changed to the expected 'ready for flight' configuration. HOWEVER, the controller display never changed showing numbers in the dots.I can confirm that the accelerometer calibration does indeed work with the 'Start First' method. For me, the calibration I enjoyed the most was the Gyro calibration . Almost no anxiety expended while that was being performed .
Regarding #1, I will say yes. I don't have an H so I can't compare behaviors directly. That said, shortly after the 'guidance lights' (for compass calibration for example) turn off, the H+ does the ascending beeping and then the motor lights flicker and turn on in the 'successfully booted' configuration. This all happens pretty quickly (maybe about 5 seconds after completion of calibration).Based on what you've described, I would continue to perform calibrations without the camera, as long as you have the cues provided that the calibration completes...
1) Does the H+ do a reboot complete with it's starting uptone, like the H does on calibrations?
2) Also like the H, do you need to manually restart the H+ after calibrating the gimbal?
