yet another rear steer question

Posted by John Moore on December 7, 2013 at 9:02am

Hey guys, I have been googling this question for a bit, an posted on another forum.  With no luck.  Hoping someone here may have some experience with this what I want to do.

What I want is rear steer.  But I dont want it independent.  I have a Spectrum DX5 5ch dual stick transmitter an receiver setup.  I want to be able to use my 5th channel (which is a switch) to enable or disable rear steer, an when enabled I want it to work with the front steering channel.

What I am thinking is power from the 5th channel an the digital signal from the steering channel.

At this time, my 4 other channels are being used with normal RC functions an my FPV.  So left stick works throttle an camera Left/Right.  My right stick works steering an camera Up/Down.  Leaving me only the 5th channel to use which is a switch.

Is this doable with the transmitter I have, or do I need to consider more channels an moving my FPV off the sticks?

    So unless I am not looking for the right thing, I am unable to find a RC Relay Switch.

     

    So I think I got a solution.

    I can buy a servo Y cable with built in servo reverser for the rear channel which would be used in a full time rear steering setup.  And then the following electronic on/off which can be ran off the 5th channel.

    This electronic on/off switch connects to the 5th channel, an then has a female servo connector which has a unused 3rd pin which could be used for the signal from the reverser.

     

    So what I need to look at now is determining which pin on a servo connector is positive, negative, an signal.

    All I am finding is a power switch which is controlled by a channel.  Are you suggesting that I provide a dedicated power source thru a BEC to the servo an branch the signal from the front servo to the rear?

    Ok, so I am fairly new to the RC hobby.  Can you please elaborate as too what your talking about how it works?

    Use an rc relay switch to control power to the rear steering servo or setup channel mixing on your tx if it has the option
