Running Twin Motors

Thanks for the info. Glad to hear I'm not breaking new ground here.

Another question. I know a single resistive type throttle can be used with two controllers, but the c-lyte controllers use the magnet/Hall Effect type of throttles. can one of these drive two controllers?

Hi GGoodrum

Techincal yes. Most controllers are controlled via a 0-5V signal generated by either voltage drop across resistor or Voltage generated by Hall Effect device.

Trying to keep the explanation simple, The input to voltage controlled devices tend to have a high Impedance-Z (resistance-R). When you parallel any Z or R that are exactly equal you created an equivalent Z or R that is half the original value(s).

With high values this is not a big issue. Ideally it would help to know the input Z so a poteniometer of the same value good be used, but rough enough will be OK here. I would propose a 10k pot be used. Wire the signal ouput from the thottle to the wiper arm of the pot. Then wire input line of each controller to remaing pot leads.

When pot is centred both controllers will receive same voltage value, from there depending on centre tap location will depend on bias.

Hope this helps

Yes, this helps a ton. Thanks, Allan.

The input impedance of a Crystalyte controller is about 150k ohms. Driving two from the same throttle should be no problem, hall or resistor.
