Introduction
You will gain more soldering experience while connecting all of the motors.
Tools
Parts
No parts specified.
-
-
Use a razor blade or hobby knife to remove excess plastic from the propellers.
-
-
-
Remove the existing nuts and washers from the threaded rod on all three motor bells.
-
Using a set of pliers, hold stationary the locknut (with the nylon insert) and rotate the motor bell to thread the nut until it protrudes out the other side.
-
Take off the nut, then put it back on backwards, nylon side first. Thread it down as shown in image 3.
-
-
-
Back the locknut up against the propeller while holding the bell in one hand.
-
Tighten this very snugly.
-
You should still be able to remove the propeller if needed, but it should not rotate freely.
-
If you are concerned about the propeller coming loose, repeat this process until tight.
-
Do this to all your motors and props.

With the 1/2" wire sleeve, begin wrapping the wires starting at the end cap. Do not wrap entire length just yet!! You'll need to pull two wires out first and it will be easier to organize wires while they are out of the sleeve.
-
Place end cap to port side of structure. This will help you measure out the length of wire.
-
Locate and separate the bright green and striped bright green/black wires. These will be for the starboard battery tube. Wrap the rest of the wires with the black cable wrap and around the frame.
-
-
-
Have the wire bundle go over the middle acrylic piece. As you wrap it over take out wires in respective order.
-
Solid green (3 wires)
-
Grey wires with stripes (4 wires)
-
Solid blue (3 wires)
-
Solid yellow (2 wires)
-
Solid red (3 wires)
-
On the other side, pull out the orange and black/orange wires. This will be for the port side battery tube and will stick out of the wire wrap similar to starboard side battery tube wires on top of the acrylic.
-
The 6 gray auxiliary wires will continue past where the orange and black/orange exit the sleeve.
-
-
-
There are two different types of insulation on the motors.
-
The first type has writing on the insulation and is sealed on the inside. No further preparation work is needed. Skip to step 17.
-
The second type has no writing on the insulation and is not sealed on the inside. There are a few preparation steps that must be completed in order to ensure a waterproof connection.
-
-
-
Starting with the starboard side, measure out where you should cut the green wires to solder the motor on.
-
Cut the wires at the desired location and strip the ends.
-
Slide a strip of heat shrink on each leg of the motor. REMEMBER TO MATCH THE CORRECT PROPELLER TO THE CORRECT SIDE.
-
-
-
Solder motor wires to the 3 green wires. The order of the three wires from the motor to the 3 green wires does not matter.
-
Slide the heat shrink over the solder joints and use a heat gun on all 3 joints. Make sure it is entirely heated on all sides to ensure the adhesive is melted inside the heat shrink and encapsulating the joint.
-
If you had to make the modifications to your motor insulation make sure that the heatshrink completely covers all the bare wire. The enameled wire will be protected against seawater, but the bare wire or the soldered area should be completely covered by completely melted heatshrink.
-
-
-
Place the vertical motor in the flange. Have the wires curl over the side as shown in image 1.
-
Estimate the length of the wires along the blue wires.
-
Cut blue wires at estimated length. Strip the ends.
-
-
-
Place port motor in flange and estimate red wire length.
-
Cut at the estimated length marker.
-
Slide heat shrink on the motor wires.
