No, v3 most certainly doesn't address J hook or TBE. Did some test flights today after waiting for rains to clear. Immediate TBE on takeoff, and sustained throughout a 6min flight. When I switch on failsafe, the P2 comes home yawed to the right by about 20degrees. I'm going to try twisting the compass clockwise by 20 degrees and see what that does. Has anyone found a workaround in areas of high declination, or are we waiting for DJI to solve this?
Yeah, be careful. You're already on the edge of a flyaway with that much declination error. You may find like I did that you have to double it to get it to fly straight from the get go but then it oddly over corrects and starts hooking the other way.
Yesterday, I rotated the compass on the landing gear leg by 41 degrees. This position coincides
with the shape of the landing gear, and the bracket which holds the compass. It feels secure
and is unlikely to shift during flight.
This morning the weather had cleared, so I took the P2 out into a field, did a compass calibration,
and waited till I had more than 7 satellites.
When I took off and hovered aprox 3mtrs in the air, there was no noticeable TBE at all.
I let it hover for about a minute, and it drifted a small amount, but no TBE.
Next I flew straight ahead in GPS mode and there was no sideways drift, nor was there any
J hook when I let go of the sticks. However, on return it drifted about 5mtrs to the right, over a distance
of about 100mtrs. I didn’t see any J hook when I let go of the sticks.
I flew around in GPS mode, circling trees, getting some nice shots, and the P2 was responding nicely.
My confidence increased.
I did two failsafe tests and both times the P2 came straight back to me, with the camera keeping
my position centred, i.e.. no drifting. Landed nicely in both failsafe landings.
Posting a video shortly of the test flight results.
