Hi, Need some help and advice. I want to install the 2.4 data-link so I can use waypoints on my laptop. I have a Phantom 1.1.1 with original board. 1. Should I install the upgrade board and fit my own canbus port, or just use PMU v2? I will not be using a zenmuse, probably go for a tarot. How much effect would the extra weight of PMU v2 have on flight time? and are there any other advantages to the upgrade? 2. I was advised by some model shops to wait a few weeks until dji release a firmware update to allow the data-link to work with the phantom, but I have seen were other people have already installed the data-link into phantom, and it works. So why are shops saying it wont work without the update? Thanks for your help, Damien.
