Steering Solution

The Steering Solution is an effective means to control steering through the application of a unique cable and pulley system attached to the rudder posts. A servo, not supplied with steering solution, powers the cable. For large props of 3" or larger, the use of a high torque is suggested for overcoming strong prop wash. The rudders can be smoothly turned 90 degrees without the steering mechanism locking up as can occur with piano wire and bell cranks. Snapping the rudders a full 90 degrees on a kort nozzle set will allow the boat to walk sideways for tight maneuvering.
