Forget the 50km link distance - that will be a theoretical link distance against a background of ideal circumstances, circumstances that are seldom defined by the manufacturer and which did certainly not include one side of the link moving/flying around. You'll be lucky if you get 5km. Don't consider that bad - it's typical in reality of most hardware that claims XXkm link distances.

Dal - spend some time looking at Ubiquiti Networks (http://www.ubnt.com/) rf link options - they produce some interesting wifi hardware. I have no experience using any of it on RC/FPV/UAV type models, but I have experience using their 700Mhz and 900Mhz wifi hardware - and set up properly its good gear quite capable of 5km -10km plus link distances in the right cirucmstances.

If you really want real world usable & reliable link distances of the sort you have in mind, then whatever hardware you use, you are going to have to use amplification - serious amplification, which is generally far more power than the average sized model will be able to practicaly carry: the battery mass will be so much that the model will have used it all up before anywhere near the theoretical distance is flown.

Your other option: take a look at http://webx.dk/rc/rc.htm. Thomas has a well established reputation for producing long distance rf link hardware that works well and is within the budgets that amatuer/hobby flyers are willing to pay.

Good luck

I'm using a nanoststion loco m2 with its built in 8dbi antenna aimed down out the bottom of the plane and I have attached two more additional 5dbi antennas to the loco m2's little pci antenna ports. This will allow the plane to have more signal diversity. For more redundancy I have a simultaneous 2.4 link as well, I'm using a loco m900 with 5dbi antenna on the craft as well for the second link. On the ground I'm using a nanostation m2 and another loco m9.
I have stp enabled on two radios.

usually stock ubnt will get you 3km range

I use only ubiquiti radios currently no other rx on the aircraft.
