Adjusting the Drive Strut
Spartan has a surface-piercing prop, meaning the prop is not fully submerged when the model is at speed. Varying the depth that the prop is
submerged will alter the model’s performance. The stock setting is 4mm above the lowest point of the hull. To adjust prop depth, loosen the drive strut
adjustment screw and angle the strut down. The minimum setting is approximately 2mm above the bottom of the hull. Submerging more of the prop
may increase speed with lower-voltage battery configurations, but amp draw will also be increased (the electronic speed control and batteries will have
to “work harder,” reducing battery life). For maximum performance with most battery configurations and in most conditions, the stock setting is best.

Removing and Installing Radio Gear
The unique design of the receiver box allows the removal and
installation of the receiver without losing the ability to maintain a
watertight seal in the box. The patent-pending wire clamp feature
gives you the ability to also install aftermarket radio systems and
maintain the watertight features of the receiver box.
Removing the Receiver
1. Remove the wire clamp by removing the two 2.5x8mm cap screws.
2. Remove the cover by removing the two 3x10mm cap screws.
3. To remove the receiver from the box, simply lift it out and set to
the side. The antenna wire is still inside the clamp area and cannot
be removed yet.
4. Unplug the servo cables from the receiver and remove the receiver.
Receiver Installation
1. Using double-sided adhesive foam tape, install the receiver into the
box. Make sure the LED light pipe is aligned with the receiver LED.
Note: For best performance, it is recommended that the receiver
be installed in the original orientation as shown.
2. Install the electronic speed control (ESC), servo, and antenna
wiring through the receiver box top (A).
3. Plug ESC and servo wires into the receiver
(see page 11).
4. Make sure the O-ring is properly seated into
the groove in the receiver box bottom so
that the cover will not pinch it or damage it
in any way.
5. Place receiver box top onto receiver box
bottom and install and tighten the two
3x10mm cap screws securely.
6. Inspect the cover to make sure that the O-ring
seal is not visible.
7. Arrange the wires neatly using the wire
guides on the receiver box top (B). Excess
ESC and servo wiring should be bundled
inside the receiver box. Pull out all available
antenna wiring from the receiver box.
8. Apply a small bead of silicone grease (part
#1647) to the foam on the wire clamp (C).
9. Install the wire clamp and tighten the two
2.5x8mm cap screws securely (D).
