If you have already followed steps to get basic range from the TBS RaceTracker and want extra-long range, you can modify the RaceTracker to mount the Bluetooth Antenna externally.
UPDATE: TBS now sells an inexepensive range extender kit:
You can also make your own. Pilots have reported 25m - 75m range with external antennas like this.

Some pilots are choosing to replace the antenna with a standard 2.4GHz receiver antenna with a UFL connector. We have verified that FrSky antennas work.
Did that make sense?
