Forgo both the TTX600 and the interface only version, get the Interlink Elite version instead.

A lot of people MISTAKENLY think that they MUST have their own transmitter hooked to a sim for best "feel" or use.

You quickly run into the limitations this produces.

- With the Interlink Elite you get more functions and buttons on the USB transmitter, which the sim will recognize, than you will with either of the other two options.

- The Interlink Elite is powered via USB, so you can merely plug it in and fly the sim. You do not have to plug in a charged transmitter.

- There is NO wear and tear on your own transmitter as a result.

- You do not have to user your TX batteries for the sim.

- The variants, helis and planes available for the sim all utilize the Interlink Elite setup.

- You can move the Interlink Elite to another computer and use the sim there without changing anything in the sim.

- There is less latency with the Interlink Elite, versus any other Transmitter hookup (on any sim) as there is less hardware "in the way".

- The RED Reset and menu buttons on the Interlink Elite don't exist on your transmitter nor on the TTX600

- The TTX600 provided with the sim does not have "training mode" ( wireless training hookups ) available, because that was sacrificed to permit it to work with the simulator...

- WIth the Interlink Elite you CAN hook up your own transmitter if you choose, but you'll quickly find that using the Interlink alone is the best choice.


etc, etc. etc.

There is a thread on the Realflight forum where people who have purchased both the TTX600 and the Interface version have come to realize all of this.

The two other options are not bad, but the Interlink Elite offers the best way of doing things.
