I'll be attempting to set up dual servo steering on a large scale (1/5) catamaran hull, using 2 Savox 1270's. I need them to operate in opposite directions for a push/pull type system. What can I use to control the action of the servo's to operate in this fashion. I have a Scott Grey HVX dual voltage regulator to use for voltage control on the HV system it will have and I also have a Gryphon Extreme-Heli voltage regulator as well so either one will work. Just trying to determine if I need a gyro or similar device to operate both servos in opposite direction's. Thanks for any and all input :)

Stupid question, but will flipping the servo's in the mount in opposite accomplish this? -
seems like it would yes. try itThere's a hole at the center of earth where the rest of the world sinks but i stand still...Comment

That should do it John. I doubt if the extra rod length on one side will affect muchOriginally posted by jj2003 View PostComment

my question is, why do you want them to go separate directions?
im visualizing two servos in my head, and even if they turn the same direction, it still should work....There's a hole at the center of earth where the rest of the world sinks but i stand still...Comment

Taking all item's out of the boxes now to try :)Originally posted by Luck as a Constant View Post

They will be mounted on their sides, so I need one to move forward and one to move reverse at the same time.Originally posted by Luck as a Constant View PostComment

wouldn't having them go opposite directions either both pull or both push at the same time?
edit: ahh ok.... now i see....There's a hole at the center of earth where the rest of the world sinks but i stand still...Comment

Testing operation now to see once all the wires are connected. I'll let you know the result's :)Originally posted by srislash View Post

It would be more normal to set up the push pull with a double ended horn on on servo as normal then run a short pushrod/s from a second servo behind it to assist. that way any minute differences in the speed or distance the servos travel are just a little extra amp draw from the servos fighting each other rather than tightening and loosening the cables allowing the rudder to flutter.

Just curious would you use a y harness or a receiver with two #1 channels.Comment

Why would you need over 900 oz of torque?

You could use an RX with dual #1 channels, or mix one stick input into 2 different channels at 100% to utilise a dual power regulator to supply power to each servo through its own connector. A Y lead would run the current from both servos through a single connector, workable but not the best use of what the OP has.
"a large scale (1/5) catamaran hull", if that is a modern offshore cat, the model would be in the region of 10 feet long. That would require some torque.Paul Upton-Taylor, Greased Weasel Racing.Comment
