This is going to be showing you how to get long range on spektrum controllers for very cheap. This is a very easy mod to do and it should work for most spektrum remotes. The parts you will need is 1 2X U.FL Mini PCI to RP-SMA Pigtail antenna wifi cable, and 1 TP-LINK 2.4GHz 8dBi Antenna. All you will need for tools is a screwdriver and some sort of saw (bandsaw works good). This should only cost around $10. Don't forget to subscribe to our youtube channel FoamyRC
This video will show this mod in action and also show you how to build it.
1. You are going to want to remove these screws on the back.
2. Pull off the antenna cover (you might need to use a little force).
3. Be careful though because there are wires inbetween the top and bottom plate.
4. For this step you are going to have to use your saw to cut off the black piece that is protruding out. Then just unplug the old wire and put the new one on.
5. Tighten the RP-SMA plug than put the screws back on. Then all you have to do is screw back on your antenna and you will be ready to fly.
When your done with this mad you should get around a 2 miles of range. Compared to stock it is way better. We are working on another mod right now that sould get you around 3 miles of range. If you want to see that don't forget to subscribe to our youtube channel FoamyRC.
THAT BEING SAID, I AM IMPRESSED BY YOUR SKILLS.

But keep in mind that antennas don't really make more output power from a transmitter. They can only take the existing transmitter output power that goes in all directions and concentrate it in a narrower range of directions. Typically, a longer antenna like the one shown here will concentrate more of the power perpendicular to it. In other words, while your radiated power might be stronger off the side of a longer vertical antenna, there will be less power radiated off its ends.
This isn't necessarily a problem, but you do need to realize that your range will increase in some directions (relative) to the antenna, but decrease in others. It will become a problem if you inadvertently turn the transmitter so that the antenna is pointing towards the aircraft -- lowering the amount of power radiated in that direction... it could be enough to cause a signal dropout.
Side note: These WiFi antennas are effective because most WiFi users are roughly at the same altitude as the wireless routers they access -- the power output is increased in the horizontal directions, but decreased vertically.
