DRAGONLINK to TURNIGY 9X HOOKUP

It is very simple to connect the Dragonlink 433MHz UHF long-range transmitter module to the Turnigy 9X (and its other labelings) without soldering due to the external access to the power and PPM signal pins on the transmitter. This takes under 30 minutes.

In this method a male-male servo connector of about 10-20cm is recommended. The crimped-on pin sockets for the power and ground leads are simply swapped at one end. No soldering is required.
The glue procedure is totally optional but helps to preserve the modular function.
At around $60 the Turnigy 9X is a great value for those fliers who might wish to more or less permanently convert it to their long-range transmitter and not feel anxious about making some permanent modifications. However this video does show one way to preserve the ability to easily exchange the Dragonlink, attached to the shell of the stock RF module, with another RF module of the proper size and pinout configuration. Though it is a cheap plastic transmitter it is relatively full-featured and you can hack it up and not feel to bad about it.
There is some potentially confusing documentation on the forums and internet in general which actually shows the JR module pinout and seems to infer that the second pin is 6v, not ground. I have tested this with continuity as well as viewed the PCB traces inside the transmitter and can confirm that pin #2 and pin #4 share a common trace and both serve as grounds on the Turnigy 9X.
Of note, the vertical transmitter antenna orientation gives the most reliable all-around performance as it tends to maintain polarity with a vertically-mounted receiver antenna on the aircraft. Horizontal orientation is documented as being mostly acceptable for casual use and can have even better long range over terrain features BUT the antenna orientation must parallel that of the receiver antenna for reliable reception. This means you must face the correct direction.
