Adjusting the Rudder Angle
Spartan features an adjustable rudder support that permits the angle
of the rudder to be changed to alter the model’s cornering feel. The
stock setting is 0°, or ‘vertical,’ meaning the rudder is parallel with the
transom (see illustration). By loosening the rudder angle adjustment
screws, the rudder can be pivoted back up to 3°. Altering the rudder
angle effects how much the rudder ‘lifts’ the hull while cornering.
Increasing the rudder angle will allow the hull to ride higher while
cornering, which may potentially raise cornering speeds but also
lessens stability. If you experiment with this feature, remember to
retighten the adjustment screws after making your setting.
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.
