ok here we go you will need a mixer a v tail mixer should do the job

that's waterproof! you will also need to use a "Y" lead so you can take a rudder feed to your rudder servo. That way your motors should give steering in addition to the rudder.

A bow thruster would be on its own channel.

NB. if you have 2 LIPOs and intend to run each motor from its own LIPO you HAVE to have a connection between the negatives from each battery so the negative rail is common.

The feed from the ESCs to the mixer should solve that for you.


if your ESCs give BEC you need to remove the positive "servo wire" from one of the ESC or you may fry your receiver.

Thank you for that, I will look into it.

You might have to buy a gadget to tel your speed control how to work it costs £8 from hobby king send for a Aquastar programming box sp500/ep800 OK with out it itwon't work ??

Given that you are fitting a bow thruster a mixer shouldn't really be necessary.

Hi, The motors are turnigy aquastar 3660-1460KV watercooled brushless motors x2
The esc's Hobby King 90a Boat esc 4A SBEC water cooled.
Batteries Turnigy 4000mAH 3S 20C Lipos.
Bow Thruster Raboesch 108-01.
Do you recommend a Mixer.

"Hi, I have water cooled brushless motors & esc's plus lipos, my TX has 6 chanels."

I am guessing that water cooled brushless motors are inrunners. While they could be used your going to have to be very careful in the choice of props. I should think outrunners would be better.

Do your ESCs have reverse? if not you need ones that do.

That's the sort of motor to provide the power you need.

ESCs need to be 60A min.

I should say you will also need a WATT meter so you can have some idea what the actual current draw of your props ( cheaper than cooked motors/ESCs).

In that case you can forget the Action Electronics diagram as its not appropriate for brushless motors.

Your brushless motor will have three wires coming off it, The speed controller will have three wires coming off one side and two wires coming off the other side coloured red and black.

The three wires will connect to the three wires on the motor, the colours of these wires are irrevelant and can be interchanged to change the direction of the motor as you wish and the two wires will connect to the battery - ensure the red goes to red and black goes to black. You may have to solder suitable connectors to the speed controller wires to make the appropriate connections. The speed controller will have a three wired connection called a BEC (battery elimination circuit) with a futaba type plug on it to connect to the receiver for the throttle channel. This saves having to use a separate battery for the receiver as power for it is supplied by the main power batteries.

If you intend to use twin motors and speed controllers it is better to connect each motor and speed controller to its own battery. in this case you will have two connectors to connect to the receiver, you can purchase a "Y" lead to join the two wires into one. if you do this you should disconnect the red lead from one of the receiver wires to prevent damage to the receiver. You may if you wish disconnect both red wires from theses plugs and use a separate 4.8v/6v battery pack for the receiver, it is entirely a personal choice.

Wiring of lights and other accessories is a separate issue.

Iam using water cooled brushless motors and esc's plus lipos.

Action Electronics provide a wiring diagram for the Model Slipway "Tamar" which can be found with the link below:

http://www.action-electronics.co.uk/pdfs/Model%20Slipway%20Tamar%2012v.pdf

This is a comprehensive diagram showing the use of just about everything Action Electronics provide and is specifically aimed at using brushed motors, a lot of the stuff will be no use with brushless motors.

brushed or brushless, how many motors, lights, anything else ? How many functions ( channels) on your TX?
