Title: Complete novice 2 engine model boat
Post by: avelon on August 07, 2018, 12:56:19 pm

Hello I want to wire up a boat with 2 engines and 2 batteries. I am a complete novice with electrics except for wiring a normal electric plug.
If anyone can help I would be very grateful, as the boat has never been in the water...…
Thank you

How many ESC's are you using and does the receiver have a battery eliminator circuit?

This is only a very basic diagram. I think I have got it right. (I am sure members on the forum will correct me if I have got it wrong)
In the diagram the motors are wired the same way, you would have to swap the connections on one motor for left and right propellers.
There are cheaper ways to do it like using 1 speed controller.
Also there are more sophisticated ways to wire things using mixers.
The connections to your receiver will depend on which channels you wish to use.
Hope this gets you started
DO NOT FORGET TO REMOVE ONE OF THE RED SPEED CONTROLLER RED WIRES FROM ITS PLUG.

I too am new to twin screws in model boats.  But I have built several single screws, and have experience with full size twin screw boats and their handling.


Here's my wiring diagram.  You can see 2 SLA 6 VDC batteries, 2 ESC's, and 2 motors.  There is one each receiver, Action Electronics Motor Mixer, and rudder servo (on the left).  There are fuses between each battery and ESC.  My boat will also have a ramp (it's a landing craft/ferry), so there is a sail winch servo on the right.


I am using the motor mixer for the first time, to give the close-in handling of a twin screw.  It will slow the port motor upon application of left rudder, and reverse the port motor for an end-for-end turn.  Same to starboard.


The ESC's are Mtronics 25 Amp, so the fuses are 20 Amp.


There is one ON/OFF switch for the whole boat, and a Power Pole connector for battery charging, both shown on the lower left.


Let us know how your build goes, and how the boat handles.
