I've been through the options now and as far as I can tell, the model name is the only difference but I've not tried ABS as I'll probably never use it. The Turnigy supplied manual does miss out Gyro calibration though.

The one thing I still don't really get is the Dual Rate. I'm used to a stick transmitter where you create a second response rate for a channel and assign a switch to change from one to the other. The full rate could be used at low speed, the low rate at high speed to prevent overcorrection. On the GT5 I cant see what it does for the throttle that can't be done in EPA settings. The setting for steering can be completly overridden with the switch on the side so why set in the menu as well?
