Speed Controller

Novak Super Roosters. Rated for 150 amps of current and are reversible. The roosters are based on a reliable H-Bridge and are controlled using RC pulses. Their original purpose is for RC Car Electric engines, however these are more than adequate for our trolling motors and have worked flawlessly as long as they are kept dry.

We have used these speed controllers for three years now and they have performed beautifully so long as they stay dry. The picture shows the results of a small amount of corrosion.

As a result of the huge currents that are being switched, the controllers generate considerable heat. To accommodate this we mounted them to the rear aluminum cap in a fan formation. This allows the controllers to dissipate as much heat as possible through the aluminum to the cooler water, though in the past we have found that the controllers continue to function normally in extreme heat (150+ F).
