Hi Don,
I have the Predator V2 and love it! Sure helps with orientation issues when you fly not to mention the fun factor!
I've not tried the Attitude but in my opinion the Predator works just fine for my needs, hard to imagine really needing something with better resolution, the Predator is quite impressive in my opinion.
I did upgrade to the 600 mW ImmersionRC transmitter along with the SpiroNET Omni, 5.8GHz CP Antennas. These transmitters only work with direct line of sight so keep that in mind when your flying. Trees, buildings even your head will all interrupt the video signal. So doing what I could to increase the range/power was a more logical step.
I mounted the 600 mW ImmersionRC transmitter under the main body of the Phantom using the PhantoMount CF Battery/Accessory Tray. I used high strength velcro (Home Depot) to attach it which seems weak I know but let me tell you its a pain in the behind to separate that Velcro. The transmitter is very light so it stays put, I covered one whole side of the transmitter in Velcro. The transmitter comes shrink wrapped in plastic which Fat Shark recommends keeping around the transmitter so that was an easy surface to attach the Velcro to.
Yes the stock Phantom charger works perfect with the Fat Shark battery which is an 2S so you plug it into the 2S port is all. They also include a little adapter.
I did not use the camera that came with the Predator, instead I hooked into the Zenmuse Gimble and the direct feed from the Hero GoPro3
The only other issue was mounting the V2's little power filter. I mounted mine right to the front of the battery storage door of the Phantom. You will have to cut a small slot in the plastic door so the balance lead can fit though. (I used a mini hack saw) This way I can use the mainPhantom battery rather than installing a second battery just for the video transmitter. I figured its about the same drain as adding the weight of a second battery.
Here are the links to the items I talked about above. I'll try to get some pictures posted a bit later on.
