    Hi,
    You can have your motors counter-rotating
    ( recommended ), and also go one step further and have two ESC's, one per motor, allowing you to have great maneuvering, like turning in a very tight circle, and crabbing sideways.
    Just ensure you have Right and Left pitch props.
    For motors, I would suggest Mabuchi type High Torque 775 motors for the Dauntless. I stock them turning 6000 rpm at 12volt.

    Ion, if you are still using the older (AM or FM Crystal) type R/C sets, which always were prone to wayward RF glitches, then yes, using 2ร— .047mf ceramic capacitors do help if you are getting glitches in the servo action caused by the brushed motors.
    I havevfound with the newer technology of the 2.4 mhz systems, they bind and lock the Tx and Rx together very well, and with all the systems I have geared up, find no glitches at all.

    I'm new to boat building and have reached a point where I'm ready to glass the hull. Questions (after reading numerous articles):what kind of resin, epoxy is best to use? I'll need some time to set and smooth.
    I used to build model planes with silk wing covering (years ago) but very little of the material I use to use is still on the market. I go to hobby shops and it seems building is becoming a lost art, everything is foam!
    Ant input would be helpfull.

    For years I had used white Lithium grease in my ShaftTubes, but forcthe last 10 years, when I build ShaftTubes, I also make a vertical oil tube at the front of the tube.
    I use SAE 80-90 Gear Lube , 15 to 20 drops in the oil tube per year.
    It is heavy enough to not drip from the tail.

    Your other option, so as to not leave you stranded out in the water, is tobuse Automotive type small circuit breaker, which will re-set after they do trip, usually in20 to 30 seconds.

    My opinion, is to protect the ESC.
    I always put the fuse between the positive motor lead and the ESC, since it is usually the motor which is the source of the amperage overload.

    S, joining both motors to the one set of ESC leads will work, but always double check the motors combined Amperage drar, not to exceed the Fuse rating or ESC capacity.

    Reversing motor rotation is simply swap (reverse) to motor leads on one motor.
    Bear in mind, if the boat had both propellors pitched (handed) left or right, you will now have one motor wanting to send you backwards and one forward.
    You will need one Right hand pitch, and one Left hand pitch, commonly available from Prop Shop, or any good model boat shop.

    Over here in Canada, we referred those rheostat friction controllers as Bob's Boards.
    They are simple, resistance type controllers, very inefficient, as voltage not used(partial throttle) gets burned off in resistance.
    Any of the modern ESCs are digital, and the circuitry allows any unused voltage to be returned back to the battery.
    The price of the newer Controllers and reliability makes them the way to go in my humble opinion.

    Yes, those controllers can run two motors, so long as you do not use batteries over 8.4 to 9 volts.

    Simy put, if both wires are same colour, if they don't work one direction, reverse your wires.
    Some LEDs have one wire longer than the other.- longer lead is often the pos.
    The wires can usually be stripped with a thumbnail or small blade.
    I solder the leads, then cover with small heat shrink tubing.

    Very old setup, and my humble opinion is to trash it all, and buy a new ESC and R/C system.
    Today's new systems are very simple, have sync-binding features which prevent glitches from wayward RF, and the new ESCs do not rely on friction to regulate the voltage/speed.
    Personally, I use and sell the Flysky brand R/C gear, and have had no troubles at all.

    Ey are great connectors, and I use them very frequently.
    The key is to use a high powered soldering gun, minimum 100 watt, not the little 35-40watt pencil soldering units.
    I always use a little solder flux in the connector socket and on the wire, then load up your soldering tip with solder, stick your wire into the wire socket then hit the joint with the solder.

    Very well built and executed model.
    The Nautical Commander was the 'Dream System' in the 90's.
    No doubt many mechanical switchery could be replaces with electronic modules. I cannot see the ESCs, and they possibly could go modern digital units if necessary.
    I see the Pittman motors, they always were very efficient, and were the standard with Dumas kits.
    I dare say your batteries will be 'Kaput', but could easily be replaced with a pair of 7.2v NiMh packs with a 'Y' cable.
    Please keep us posted on your progress.

    These are great gear-motors, known as Decaperms.
    I believe they are rated for 12 volt, and your ESC is also rated for 12volt, they were sold in North America through Horizon Hobby
    I have sold many of these over the years.

    Your simple fix, if you do not want to have two independent throttles, is to hook both motors to ONE ESC, and ensure your ESC has the capability to handle the amperage draw from both motors
    If you choose to use TWO ESCs, and still use one throttle stick, then you would use a "Y' Servo adapter to plug both Controllers into the one Receiver channel slot.

    Def use a U-Joint Coupler if possible and actually a double articulated coupler is ideal of there is much mis-alignment.
    At times I have doubled up(back-to-back) individual U-Joint couplers to take up any variances.
    Depending on which type motor mount, either hinged, or home-made, always allow for adjustment in the aligment.

    There are two types of Acid Batteries, 1- the WET ACID batteries( in cars), and 2- SEALED LEAD ACID(SLA) known as Gel Cells. As the name implies, these have the acid in a gel, and the batteries are sealed allowing them to be placed in any position.
    Gel Cell Batteries are great for any larger, displacement hull models, where weight is often required to trim the boat down to the waterline. You can add multiple batteries as needed simply by wiring them in parallel, to keep same voltage, but adding up the storage amperage, basically giving you more run time.
    See pic of one of my setups with two Gel Cells laying flat.

    Ok, my Newbie friend- we all start somewhere, and you were wise to search out which way to turn, rather than buying g parts which may not work for you.
    If you have a suitable motor hooked up, there is step #1. Next, R/C equipment will require a Transmitter(Hand Set) and Receiver(Boat piece), plus An Electronic Speed Controller(ESC).These little units will give you full For/Rev control plus it will take power from your main batteries to power your electronics in the boat. Most all ESC's now have a BEC (Battery Eliminator Circuit), which backfeed 4.5 to 6v to power the Receiver.
    Depending on the Voltage required for the motor, will determine which batteries you need.
    For simplicity sake, I will assume your motor is brushed, rated for 6v to 8v.- Therefore, the cheaper solution is to use two standard NiMh 7.2v battery packs, wired to keep 7.2volt, with double the amperage storage( if 3000ma each, you would have 6000milli-amp total usable power.) You can modify the wiring for this feature, or I sell the proper wiring couplers to join both battery packs. The Battery pack now plugs into the (+,-) ESC, then plug the ESC motor leads to the motor.- These wires can be reversed if your motor turns the wrong direction per the Tx stick if the Transmitter does not have the Servo Reversing option.
    Lastly, you will plug the ESC into the appropriate channel slot in the small Receiver.
    Of course, your Rudder Servo plugs into a horizontal stick Rx slot too.
    When I supply R/C setups for customers, I also supply custom wiring harness with Fuse, 3 way DPDT switch and Charging Circuit.
    Any decent Hobby Shop in your area will steer you right in matching up the proper Radio, ESC and Battery Packs you need or I can also supply all you need.
    I have a fully stocked Model Boat Shop, here in New Brunswick, Canada, but I ship parts all over the world.

    Regarding Standard Servo sizes, there are Standard size Servos, similar to the Futaba/Robbe S33, and there are the mini(micro servo) which are less than half the size of Standard, used in tight quarters.
    I can post pics if needed.
