Hallo guy...
I will ask you a little question...
I've got a Phantom 3 Professional and a Phantom 4.
The HDMI module is on Phantom 3's Radio.
Could I switch it from here to Phantom 4 RC and each other?
Is it complicated?
I didnt't thought to that... because thought to sell the phantom 3...
But if you link as you said how could run the sport mode on P4?...
Switches on Radios are different...
Moving the HDMI board over is SUPER easy. But, Aardvark is right, the transmitters are interchangable. On the "switch" p4 = "S" and p3 = "A" .. but it does the same thing.
Basically, it requires 4 screws on the back, remove the plastic piece and then 3 screws to undue the board. You have to unclip 3 ribbons, 2 are kinda small so be careful. Pull it out, put the new board in and carefully put the ribbons back in place,t hen the plastic cover. It was really one of the easiest mods I've done on the phantom, adn the video above is pretty good.
Strange thing: i have a phantom 3 advanced, and have installed the HDMI module and a DBS antenna for better range, then i bought a phantom 4 and used my phantom 3 advanced controller for the antenna mod. which all works fine. I always though as far as range goes the phantom 3 a was better but after the new controller updates i found that the phantom 4 had MUCH better range than my Phantom 3 advanced.
