Sorry about the missing link maybe I found it on a forum anyway I had a look on youtube & this is the one

There are several other clips but that's the one I referred to, the range of transmission is at least 2km according to that partic user. In my search I found another branded one where the bloke flew an electric plane about 4km around an oil rig then back again so there are plenty of people out there doing what you want to do with the ranges more than you need but your right just not with a iPhone. However I don't think the iPhone platform is the most flexible for your needs loading a iPhone in your aircraft compared to a dedicated video/telemetry suite is a big weight difference added to the fact that you will have to adapt a existent SDK or program your own app to get the data into then transmitted out of the iPhone on the aircraft as well as to display the data/video on the receiving iPhone this will give you plenty of things to work on personally I wouldn't want to lose a phone if the aircraft went missing 2kms away tho I suppose "find my iPhone" app would find a brand new use, using the phone infrastructure also limits you to the areas where there is a Phone system & you are also at the whim of the phone system provider & in some outer areas the addition of an extra phone on the area will make your connection drop out leading to a lost control situation certainly a loss of bandwidth hence dropping the video feed (that would be part of the design params where there would have to be a staged loss of function) with a last ditch resort of circle in place on total loss of connection (Parrot drones land if you get a phone call while flying them).
Personally I think if you really want to go down the Mobile phone path you will need to talk to the Motorsport groups & look at the smallest GSM Modem that you can get your hands on the areas that you need to research will include the data rate achievable via a phone connection as tx'ing live video as well as rx commands may actually exceed the bandwidth of a mobile phone connection or you will have to compromise on the quality of the video. Having said that with the number of dinky little helicopters (Jaycar sell one that's iPhone compat), the Parrot Drones(which have HD video already built in) & the Car mounted system you found it probably won't be long before what you want becomes available - you might even be the one who makes it happen, this is probably a candidate for a bit of crowd funding if its really popular.
So again not really solved but something to think about
