Hi

i need the differences between the DJI Phantom 2 vision+ V 3.0   and V2.0
I´m really confused about all the updates.

thanks

v3.0 has "upgraded motors, propellers, remote control, ESC, and compass"
Remote control has a new wheel to control the gimbal (for v2.0 we use the phone to control the gimbal)
Propellers are better (9450 vs 9443) and motors are more powerful. The compass is integrated in the landing gear and I'm not sure if it's better hardware. ESCs are upgraded to work with the new motors, I think.

You can add increased GPS shielding to the top cover and internal RF shielding to some of the cables to that list.

I have a P2V3 and bought some new propellers - of course the "old" ones. Can I use them together?

No, they are a different profile.
Do NOT mix and match propellers of a different pitch.

Bad news, didn't realize this small number. I have already done some flights with mixed propellers, no issues so far but I will not do it again. Looks like I need to buy some propellers

There are a number of other little tweak...RF chokes on a lot of the cabling, different connectors (previously in v 2.0, the plug that connects the GPS puck to the mainboard was notoriously loose and came off easily. No doubt the source of at least a few flyaways.?
