I want an to get an FPV setup with reasonable range and performance, but have a number of questions before I pull the trigger, any and all help would be greatly appreciated. Currently I have a Phantom 2 v2.0 with a H3-3D gimbal and GoPro Hero 3+. I am looking at the Flysight Black Pearl All in One FPV Combo Package + DJI iOSD: - In general, is this a good option? - Do I need anything in addition to the kit and iOSD module? - I am a bit confused about whether I need DJI's FPV hub, it appears to me it is optional. Why would I choose to use it?
