Well that is stupid place to build it......

😁

At least you don't have to get it out of a cellar as to moving it by the sounds of it your going to need a trailer, why not build your next a little bigger then you can ride on and go for pure manual control.



My back wouldn't be able to handle getting a beast like that in and out of the water

The Model is to big for the bath, I will need to some how take it to park, I think it is to big for the car as well so it could be interesting.

😰

Use a locknut !!!! And if they still come off in the test tank ( or as my better half insists bathtub) try some blue thread lock.

Yes, I have the Running set for HMS Blake from GT Siteck with LH/RH Props, I always put them on wrong and loose them.


😯

please remember you will need right and left hand props otherwise your going no place

Okay will try that and switch my wiring around.

I did include a diagram but putting it simply.

Brushed motors have 2 wires lets call them blue and yellow.

if yellow is connected to positive and blue negative the motor turns in one direction. Reverse the connections and you reverse the direction.


Look at the diagram I have motor wires as blue and yellow.

in practice you would make the connections at or near to the esc.

Just explain how I would do that?

one motor of each pair clockwise one antI clockwise.

That way the torque effects are balanced out.

if motors each side of a rudder run in opposite directions the differential effects of the propwash on the rudder are also negated.

Reversing?

💭

did you consider reversing 2 of the motors to even out torque?

. 😀

Now sorted the servo was not working because it was set up incorrectly. Many thanks to all who posted.

Changed the wiring motors working although the starboard inner runs slow and is noisy, may have a bent shaft. Small problem the rudder servo is not working. I have connected this to channel 2 changed leads still not working
Will try changing the channels on the receiver.
😟

Well starting with a clean sheet I would have the two centre motors on just throttle and the two outer on a throttle rudder mixer so a min of 3 ESCs.

Throw in a bow thruster and its getting complicated.

if you use brushless motors then its one ESC per motor.

I think I tried my Rother class Lifeboat with series wiring, but that's over 15 yrs ago. Then I started buying multI channel radio sets, so all my twin motor setups are independent,(obviously 4 is a different ball game.
I set twins up using a tacho so both run at same speed at full throttle.

You could series connect them BUT you not going to get increased revs that way.

in parallel each motor gets full battery voltage.

in series each gets half voltage.

Since motor speed is proportional to supplied voltage ( there are a shed load of other factors but for given battery motor setup) the effect would be the same as connecting each motor to 6 instead of 12 volts.

You may want to consider having one motor from each pair running in reverse rotation to even out torque effects.

VMT will change my configuration. 👍

HI Derek
It is not advisable. As Haverlock advised put them in Parallel.
I have seen a serial set up where the motors were low voltage, say both 6v and a 12v battery was the supply, but the result will depend on how well matched are the two motors. Usually one will run much faster than the other due to manufacturing tolerances. At slow speed one motor may not start as quickly as the other.
Used in parallel this will not be a problem.

I have somewhere that with 2 motors one controller, they had been connected in series. Think it gives a more even rpm between the motors. So would be same as Haverlock says,2 left and 2 right together.
Wait and see if someone with experience of this comments. Or just experiment with direct connections to a battery.

Okay will give that a try. 👍

with 2 ESCs you can pair the motors connect them in parallel.

The 360 is listed as a 4A stall current @12 Volt so a 20A speed controller should handle 2 motors easily.

Pair them right and left so 2 right hand side and 2 left hand side then connect to the ESC(s).

You can treat each pair as a single motor so same as your 2 motor setup.

Have a look at this diagram
