SIMSTICK ia a great looking USB interface device that will allow you to connect to your PC without using the wires. Anytime you want to use your simulator just turn on your transmitter and it will instantly connect. There is no appreciable loss in latency and it will even allow you to fly with transmitters that do not have a trainer port (i.e. DX7 SE).
Whether you are a RC helicopter or plane pilot there are many advantages to practicing on an RC flight simulator. Simstick is compatible with most Spektrum based radios including the DX8 and the majority of 6 channel receivers with a narrow pin spacing.
