Curious to know in your travels if you've seen differences in the the compass hook as you've covered a lot of ground.
Ian:
I noticed very little drift or hooking (in either direction) on my P2s during this last cross country trip. But the zinger is that after 40+ broken P2 props, in mid-March I switched exclusively to 8.5" DJI props. Later, I discovered I had been mixing the 10" XOXO knock-offs with actual 10" DJI props and the results were horrendous. In retrospect, this was doubtless the main source of my control problems.
With the 8.5" props, the P2s are far quieter, more responsive and vastly easier to control in 15mph+ breezes -- which seems to be the only wind conditions I've been able to find so far this year. I've dinged a bunch, but have yet to actually break an 8.5" prop.
With gimbal, FPV TX, and OSD I get about 10 minutes of flying time before reaching my 25% battery level warning. That would be flying in a 15-20 mph breeze at roughly 50% GPS, 25% ATTI, and 25% HL/CL.
While driving across country, I typically did a compass correction every morning -- about every 8 to 9 degrees of latitude.
I just finished setting up a trip to CO, WY, and SD in early July (the Rockies are hosting the Dodgers at Coors Field for the July 4th weekend). I'll make a couple of flights around NY with the 10" props before I go, and see if I observe any difference in hooking or drifting when I reach the Rockies.
Given DJI's ability to program in GPS lookup tables for those inverted wedding-cake shaped ATC-no-fly zones into the 3.0 update, it seems that adding deviation tables would be, well, real a piece of cake.
