Alright guys, the stage-2 booster for iOS is ready for beta testing. We might add more features to it, depending on the feedback of the first round beta testing. As we are running low of UDID quota, the first round beta testing is only for those iDevices participated in the previous iOS beta. Please PM me if you are interested and you don't need to send UDID again, I will send you the download link.
There are 6 levels of interference. The higher interference level (highest is 6 - Urban), the better FPV range in urban area but worse in open area. The lower interference level (lowest is 1 - Open), the better FPV range in open area but worse in urban area.
