MOA Dig Controller for Two Position Channel

[heyok]

This dig controller will give you all three modes of operation with a Two Position Channel.

You will have four wheel drive, front dig and rear dig.

Don't feel left out of a full functioning rig if your transmitter only has a two position third channel like on a DX3.0 or an unmodified TQ3 etc.

If you have seen my thread on the Winch Controller for Two Position Channel, it works in a similar fashion.

Each time you toggle the third channel, it will change modes.

First, on power up, it would be in 4WD

• Toggle CH3, now Front Wheel Drive (rear locked)
• Toggle CH3, now in 4WD
• Toggle CH3, now Rear Wheel Drive (front locked)
• Toggle CH3, now in 4WD

etc.





Part No. DIG2 $65 plus shipping.

I have a gt3b flysky that would work?

And the pos & neg leads comeing from esc is that from batt or motor?

Those are the ESC output wires that would normally go to a motor.
I left off the leads that go to the battery in the drawing.

Yes, it would work great with that transmitter!

Rather than guess, I will ask you what you mean by "cheepest"?

65 is a great price.

May have to invest in this....

Thank you sir!

How are these holding up. This is the first time I have seen these. Pretty much what I'm looking for to use with my dx3s. Are there any instal threads here on the board?

I haven't received one complaint about these.
Actually, there was one... I forget who it was, but he had some trouble soldering and I think applied a little too much heat when soldering on the motor leads. He sent it back to me, I repaired it and soldered on wires for him.

I found a couple of mentions of the dig controller:

i got a scale truck that i'm putting a water pump on for in my mom's garden (i'm lazy), can i get a diagram of the main electronics that control the relay i want to set it up so i can turn the pump on and off with the third channel on my controller and this moa system looks like a cool why to set it up.

What sort of voltage and current do you need to run your pump?

well i'm not to sure yet I've got an old 20t motor i was going to put on the pump and i was thinking of running the pump on a two cell lipo.

Are you looking to buy a controller from me to operate your pump or are you asking me to give you the circuit diagram?

i would rather the diagram, i want to build as much as i can for this.

Moving this conversation to PMs to discuss giving out my work.

So If you are running dual esc's, which one do you wire to the dig switch?
Thanks alot

The one you don't want to put back on the shelf

If you are going to run dual ESCs, the MOA dig controller really isn't for you. For that, you would want a transmitter that can do a mix on the throttle and another channel. The GT3B or GT3C with the firmware hack is ideal.

If you want to use a transmitter with a two position third channel to control your dig, then this is the right product for you. It only requires one ESC to do it.

You would connect it just like in this drawing:



What the dig switch will do is direct the power from the one ESC to both motors, or just the front motor, or the just the rear motor. When only one motor is getting power, the controller puts an electrical short across the motor that is stopped which acts as a brake and locks (or slows) that axle.

Did that description help?

[rockpanda]

Thanks for your reply,
I have the esc's set up in one channel, a y connector for the power. I have a turnigy GTx3 which is just a cheap Flysky, exactly the same. there is a 2 pos button as a 3rd channel which i would use. So its slightly different to the diagram as each esc provides a motor power.

Thanks
