Spektrum DX6e Throttle setup (Forward/Reverse at the flick of a switch)
 

Hello friends.

My hobby is robotic combat, hence the odd request that I would like a little help on. Most combat robots have their active weapon (spinning blades, bars, saws) controlled via their throttle stick. In my robot, it is currently setup so when the throttle stick is centered, the weapon doesn't move. When its pushed forward, the weapon spins in a forward motion, and the opposite for when the stick is pulled back. I have the "no-spring" configuration for the throttle stick at the moment.

What I am having a hard time figuring out is how to set it up so the throttle travel goes from 0 - 100 when a switch is in position 1, and then 0 - -100 when a switch is in position 2. This is so I don't have to find 0 when the fight is over or have to worry about it accidentally getting nudged in the few moments that it takes to turn it off. It also is great so if my robot gets flipped upside down, I just flip a switch to reverse the motor and keep on fighting like normal.

Does anybody know how I can do this?

Thanks,

David

I hard a hard time figuring how to do this myself but the trick is to manipulate the throttle curves activated by switches. The throttle curve maps the full travel of the throttle input to whatever output values you program the curve to output. So, for instance, if you would like your 100,100 travel to give 0-100, you map 100-100 to 0-100 (this might be confusing because the input and output values are written as percentages of the entire travel. so you would be mapping 0%-100% to 50%-100%)... for negative throttle, you need to map 100-100 to 0 - -100 which corresponds to mapping 0-100% to 50%-0%.

Hope this helps.
