Kangaroo Setup???
Tommy,
I have my brakes setup on a slider and will sometimes just set them to partial with the slider before landing for short fields. Down elevator on a hot landing with the Roo would be disastor, I think you can set up a mix using the snap roll switch and or at least the three position switch. I have an 8103 (heli version) the flgith mode switch is in the upper left corner I don't know where it is on the airplane version (switches and knobs are in different places) I know you could use that and setup different settings. Myabe even mix that with a knob so you can adjust the brakes. Either way we can help you figure that out, I know any of us will be glad to give you a hand.
