Title: Using the TX switches for motor
Post by: PhilandIom on August 02, 2016, 09:13:52 PM
I am building a sailing lugger fishing boat (Louis Heloise). I would like to use the TX on/off channel switch to run the motor as a self rescue. What is the minimum electronics I need and how do I wire it, I don't need speed control just a simple on/off control to get the boat back when the wind dies mid lake. I am thinking of using a separate battery to power it.

Cheapest is a servo with a switch attached.  The TX switch alters the state of its channel, the servo moves, operates the switch.
Next up is a switcher, basically a set of servo electronics that operates a relay or equivalent.

For me a pure electronic solution switching a motor seems easiest and cheepest

Turnigy electronic switches are only a couple of quid and no need
to make up a servo/switch board.
Easier and can be positioned just about anywhere.

I think my cheap electronic switcher would not like the startup
current of a motor and would need to have a relay to switch
the motor supply as Malcolm has said.


Sorry for posting before thinking <:(

pololu solid state switches. they plug into the RX and have a low side driver, (they switch the negative side). active robots is one source, and uk.
