I have a P1 and am considering installing an iOS mini. It requires either a NAZA V2 or the PMU V2 (whatever that is). I THINK I remember from last time I opened the bird that I have NAZA V2....and my Assistant in the title line shows NAZA V2 (altho it does that even when NOT connected to the bird). Yes, I can open the bird, risk stripping screws and bolts....OR....is there another way of determining if I have the NAZA V2 WITHOUT opening the bird? Thanks.
