Pro Boat’s new waterproof marine electronic speed control is definitely one of the best new values in model boating. Anyone can upgrade their RTR boat from a mechanical speed control to the precision of a fully proportional ESC with reverse.
The unit’s completely potted electronics are sealed in epoxy and encased in a blue anodized aluminum shell that keeps operating temps cool. In addition to being inexpensive and waterproof, no programming is required. Set up is as simple as turning on the transmitter, turning on the receiver and moving the throttle to full forward, then full reverse. The speed control automatically memorizes the initial movements and provides proportional control between the extremes.
