Anyone know how to scale throttle based on one of the transmitter wheels. For example %50 on this wheel would scale throttle %50. There are videos showing the OpenTX setup but not seeing Deviation yet

Use a complex mixer. Set it up however you like for normal throttle control. Then add one more mixer. On that page set Src to the wheel you want to use, and set the Mux to mult. With a 1-to-1 curve putting the wheet at 100% gives 100% of the throttle mix. Wheel at 0% (midpoint) kills throttle completely.

Close, it’s scaling the top of the throttle like I want but it’s also scaling the bottom of the throttle. At the top of the wheel I have normal -100 to +100 range. At slightly lower than top of wheel I have -80 to +80 instead of the needed -100 to +80

Think I found it, I changed to min instead of mult. Now I always have -100 but the top end gets scaled

Never mind, that plain cuts it off instead of scaling it

I think you need scale "mult" mux from 0 to +100%. Offset = 50, Scale =50. If you need different scaling, adjust Offset and Scale to proper values.

For example, if you need 30% to 100% scale, Offset = 65, Scale = 35.

Can’t get it to work, not sure what I’m doing. The OpenTx version has you add another mixer with Add and scale 50 offset -50 but that’s not doing it
