Interesting that some use both. I too have always used down elevator, but wished I had a parking brake. Is it fairly simple to program the slider if I already have the down elevator set up? Never even new that was possible. I learn something new everyday! Oh, I have a JR 9303 BTW.
Yes it's possible and easy. Assign the brakes to one of the sliders and set it up to operate the brakes. Use your existing elevator to brakes mix to operate the brakes with the slider off. Progam both brake mixes to be inhibited with the gear up switch so as not to waste air during the flight.
Note: These two elevator/brake mixes are cumulative so make sure the slider is off after using it for a parking brake for "normal" down elevator braking.
Note 2: You can fine tune just when the down elevator brakes start to actuate by putting in just a little slider movement. It best to have the down elevator brakes begin with just a small amount of down elevator.
