Built for Combat from the Ground Up Most AM32 ESCs started life as BlHeli32 designs and were flashed to AM32 later — the Just Cuz Robotics AM32 ESC is different. The RevvitRC 50A was developed for AM32 from the ground up, which means zero loss of functionality. Low voltage cutoff, current limits, thermal protection, and telemetry all work exactly as intended. No compromises, no missing features — just a clean, purpose-built combat ESC that does exactly what it says. What It’s For At 50A continuous on 3–6S, the RevvitRC is sized for serious work — 3lb weapon motors, 12lb drive systems, and anything else that demands high current and reliable response. It pairs perfectly with the JCR RDY-5735 950KV, RDY-5735 750KV, RDY-5536 900KV, RDY-5536 1200KV, and the RDY-5022 hubmotor lineup — sensorless brushless motors that demand exactly this kind of high-current, high-response ESC. It also works well as a drive ESC for larger bots. As always, verify your needs and design vs the specs of the ESC to make sure it’s a reasonable fit. The Onboard BEC The RevvitRC is the only brushless ESC in the Just ‘Cuz lineup with a built-in BEC capable of powering not just a receiver, but servos as well. The BEC output is switchable between 7.4V and 8.4V via an onboard DIP switch, with a 5A load rating — plenty for high-torque servos and accessories. This makes it particularly well suited for bots with active weapons or mechanisms that need servo power without a separate BEC. ⚠ BEC Warning — Read Before Wiring Do not connect more than one BEC to your receiver. If you have multiple ESCs or BEC sources in your build, cut the red wire from all but one BEC voltage source to your receiver. Failure to do so can damage your receiver and electronics. Verify your receiver’s voltage rating before connecting. The RevvitRC BEC outputs 7.4V or 8.4V — significantly higher than a standard 5V BEC. Not all receivers support these voltages. Check your receiver’s specifications carefully before powering up. Default Configuration and Programming Out of the box, the RevvitRC ships configured as a Brushless Weapon ESC — single direction, braking disabled. No programming required for most weapon applications; just wire it up and run. If you need to switch to drive mode, reverse direction, enable braking, or fine-tune any parameters, every RevvitRC ships with a USB-C programmer so you can adjust settings via the AM32 config tool. You can also use the Grey Skies ESC Programmer available at ItGresa. Note: the ESC must be connected to a battery for power when programming — the programmer does not power the ESC. For a full explanation of all AM32 settings, see the AM32 firmware settings wiki. Before adjusting any parameters, Just ‘Cuz strongly recommends watching this setup video first. ⚠ Programming Caution Do not arbitrarily adjust startup power or startup level settings. If these parameters are set too high, the ESC can burn out immediately on power-up. If you’re unsure, leave the defaults alone — they work well for most combat applications. Wiring & Power Distribution Need a clean way to wire your bot? The RevvitRC pairs seamlessly with Just ‘Cuz power distribution boards — the Switch PD Board, the Long All-in-One PD Board v2.1, or the Basic PD Board — all stocked at ItGresa. Each brings power switching and distribution into one clean solution, eliminating rats-nest wiring in tight chassis.
