Also, i did have a question regarding some parts of the menu. When you assign a key as BRK, what does this do? does it just disable reverse on the trigger temporarily when its activated and then use reverse on the trigger to what you set in the mix menu for the brake channel, and then make the trigger go back to reverse if it's off?

I'm working on a conversion, and it has a disk brake on the rear axle. i don't want to use motor braking, because it's a chain drive. I doubt i'll get a response to this though.
