The GPro differences I see:
- More compact on the length and height sides (but GPro is nearly an inch longer on width)
- Space for only 3 batteries instead of XRV+'s 5
- No wheels! The horror!
- No support under the quad's arms. To me, this is the most concerning difference. It's not cradling the P2V+, it's just kinda sitting by itself in the cavity. (To be fair, I don't like that the XRV+ has no cradling of the lower half/gimble, but at least the arms are secure)
- Similarly, no separation between the Phantom and the transmitter. In
the picture, you can make out a little stopper in the cavity where the transmitter sits, but it just doesn't
seem as safe as the XRV+. It very well could be fine.
All in all, you've got a $30 difference (minus shipping), plus some space considerations. Objectively, I don't think you'll be making a bad choice either way.
