Throttle Direction Switch

[Deathstick]

I have a Spektrum DX7 and want to program it to achieve the following for a DC motor: Flip a switch and the throttle lever becomes active rotating the motor Clockwise, for example when stick is down it is at 0%, when stick is up it is at 100%. Then flip the same switch to position 2 and the motor direction is reversed to CCW, and the throttle stick functions in the same way down is 0% up is 100%. Let me know if you have any ideas on how to achieve this.

Very curious as to why you wish to do it? This sounds like a recipe for a crash. With that said however I am always open to new ideas or ways of doing things.

Simply set up individual throttle curves assigned to different flight modes - look at TX manual on how to do this.

So how is this not doable with a conventional reversing speed control, such as the ones for scale boats, etc?

It is for a cable cam drive, I tried setting up throttle curves but I was only able to accomplish reversing the stick direction for input but not motor direction. So my curves look like this: norm: low stick is 0% hight is 100%. Mode 2: low stick is 100% hight stick is 0%. As there is no negative values, what can be done to reverse output direction.

It does work that way but I need it on the throttle stick so it can be released and stay at that position, and not have to struggle to find middle stick position when in a hurry.

So, file a notch in the throttle stick gimbal brake at mid-stick and you're done. We did this all the time when I was doing scale boats 30 years ago.

Just make your throttle a centring stick, easy to do on most modern radios.
