I ordered a phantom 2 and the new zenmuse h3-3d gimbal. However the p2 is not the very latest version with what I've heard to have a modified belly for the gimbal and preinstalled firmware. I will be able to use the gimbal with an extra mounting plate but my question is should I send it back and wait on the newer model? Is the only difference the "easier" mounting and firmware? Any other differences? I mean, it's not hard to upgrade the firmware. What are your opinions? Am I missing anything here? Thanks!
