I have DJI Vision, DJI Ultimate Flight, FPV Booster, and I just bought Vision Pilot because it has POI. I have a P2V+ v3.0 and I bought an Acer 8" tablet for this so I can see it better than on my Galaxy S5.
Well, as it turns out, Vision Pilot can only do POI if my tablet has a compass in it, which it does not. Nice. He got my money and I got squat.
I still use the tablet but I gave up on POI (and Vision Pilot) and I am learning to fly a circle and keep the nose pointed in myself. I did the slow yaw mod, it works great! I reverted back to DJI Ultimate Flight. I feel the safest with this one.
Now for my question finally: Will Litchy need a compass in the tablet to perform POI and follow me?
