The only difference with my dual motor installation is the switch. You show a double pole switch. I use separate switches for each ESC as mine usually come pre-wired with the switch.

Pat Apologies I attached the wrong image here is the correct one

We always use two separate speed controllers and wire them up as shown. We have used this approach for over 15 years and have had no issues. Hope it may help

P96 is a servomorph unit. P94 has 2 x 20 amp escs and the P94 L has 2 x10 amp escs.

Yes it does.

Does the P96 allow you to go ahead on one engine and astern on the other ?

Outstanding info here Gang! Thanks to all!

I use the Action P94 on my Harbour Tug in the tank steering mode and it works great.

Hi Pat. I like to use the Action P94 dual escape plus mixer. I have one in my LCM6 and I am just upgrading the power train in HMS Manchester. Manchester is getting a parallel power board, to safely connect two batteries without fear of back charging, two fuse boards and the P94, which is programmable for various combinations of motor/rudder mixing. I can scan the instructions if you want to have a look.

On my current build which has two motors I have 2 x ESC's combined with a W-Tail mixer. The W tail mixer assists with steering as it speeds up one prop when turning and also controls the rudder where as I believe a V-Tail mixer doesn't control the rudder. The MTroniks one that I have will also handle 3 screws if required.

I use two ESCs in all of my multi prop boats. Gives much better control especially when docking.

Be careful when talking about current. Sure, a motor might run at 2 or 3 amps but check out the stall current. It can be many times that particularly if you have a weed problem.

Also note that when using multiple ESCs, most likely you will need to cut one of the power wires from the ESC to the receiver. This is so you are not running power to the receiver from two different sources (ESCs).

Hi Pat.
I have one esc in my HDML to control two brushed motors with one contra-rotating, without any problems. The two motors are drawing only 2 to 3 amps each and my esc is a 15 amp mtronics one.
Runs for ages with two 5amp nimh 7.4v batteries set up in parallel ( mainly for the ballast they give ). I pack up much sooner than the boat ever does.😁

If using brushed motors you can use either - if using one ESC you use a Y lead. Benefit, if needed, of using two is that each motor can be independently controlled, but then Tx control gets more complicated.

If using brushless motors then you need two ESCs. I have read of folks only using one but that was using an expensive ESC that could handle two motors.
