Splitting an RC channel into two full range channels

[Jamez_Warner 0]

I have a requirement to use one axis of the right stick of my transmitter to control two RC channels, ie: the top portion controls one servo full range and beneath controls a different servo, also full range.

I know it would be easy with a PIC, but are there any commercial circuits to allow this?

Not that I know of. But depending on what radio you have you could use mixes to achieve that using 2 channels controlled by the same stick.

Couldn't you just use a y connect and flip servo's to which ever way works? Or use a special y connector that reverses servo... couple other tricks. Otherwise kilrah is right in just using the 2 channels and mix.

The mix might work, but I want each half of the stick to control a servo wholey, ie:

Top - Servo 1 at max, servo 2at min

middle - Servo 1 at min, servo 2at min

bottom - Servo 1 at min, servo 2at max

Not sure the mix would achieve this?

That depends on the radio... on mine I could do that. If you have curve type mixes you should be able to do it.
