Viper Auto Sport 20, speed controller, waterproof

The Viper Auto Sport 20 speed controller brings waterproof electronic motor control to brushed RC model setups in a compact 40 x 35 x 12 mm format. With forward, reverse and brake functions, it gives the drivetrain clear throttle response while the 54 g weight with cable keeps the unit easy to place in tighter chassis layouts. Programming is handled through 1 setup button, so the controller can be configured without a complex menu structure. The stated 20 Turn motor limit defines its intended brushed motor range, and NiMH compatibility with 4 to 8 cells at 4.8 to 9.6 V covers common hobby configurations. An integrated fail safe is built in as a concrete control feature, and the electronics also include short-circuit protection, overload protection, an on off switch and complete wiring. The listed 3.3 k frequency and 1.5 A BEC output add further technical detail for model builders comparing drive components. In a touring car, buggy or other electric RC vehicle, the compact case and attached leads support tidy routing between battery, motor and receiver. Wet track sessions, club running and general hobby use all benefit from a controller that combines waterproof construction, direct setup and clearly stated electrical limits.
