The Antweight Weapon ESC Spec’ed by Repeat Robotics The ReadytoSky 35A weapon ESC is the electronic speed controller spec’ed by Repeat Robotics for the Scalar antweight combat robot kit. ReadytoSky produces this ESC for the drone and RC market, but Repeat Robotics identified it as an ideal match for antweight weapon systems and pre-tunes it specifically for combat use — boosting startup power to reduce spinup times and deliver more aggression at low RPM. If you’re running a Scalar or building a custom antweight horizontal spinner, this is a proven, affordable starting point. Pre-Tuned for Weapon Performance Most ESCs ship with firmware tuned for smooth throttle response in drone or aircraft applications. That’s the wrong profile for a combat weapon motor, which needs maximum torque and fast spinup from a standing start. Repeat Robotics addresses this by pre-tuning the BLHeli_S firmware settings on this ESC before it ships — so you get better weapon performance without having to configure anything yourself. It’s plug-and-play ready for the Scalar weapon system. Capable Specs in a Tiny Package At 13×29mm and just 6g, this antweight brushless ESC fits easily into the tight confines of an antweight chassis without consuming precious weight budget. It handles 35A continuous current and accepts 2-6S LiPo input, giving you headroom for higher voltage weapon setups while staying well within antweight power budgets. The onboard programmable LED lets you confirm settings at a glance. The motor output pads use plated through-holes (PTH) — a legitimate engineering advantage over flat surface pads. Feed your motor wire through the hole before soldering and you get mechanical retention during the solder joint, better wetting, lower risk of cold joints, and a more fracture-resistant connection under the vibration and shock loads of combat. It’s a small detail that makes a real difference on the bench and in the arena. BLHeli_S Firmware BLHeli_S is one of the most widely used and well-documented ESC firmware platforms in the hobby. Configuration is handled via the BLHeli Suite software, which is free and runs on Windows and Mac. If you’re stepping up from a FingerTech BL20A or trying a higher-current ESC for the first time, the BLHeli_S interface will be immediately familiar. Need reversing capability for a drive ESC? Check out the FingerTech BL20A Reversing as a companion for your drive system. Note that BLHeli_S and BLHeli_32 are different firmware platforms — if you’ve heard that BLHeli_32 is exiting the market, that doesn’t affect this ESC. BLHeli_S is a separate, fully supported platform with an active community and no end-of-life concerns. You’re not buying into a dead end. No BEC — Plan Your Power Accordingly This ESC does not include a BEC, so your receiver will need to be powered by your drive ESC or a separate BEC. This is standard practice in antweight weapon builds and is how the Scalar kit is wired. If you’re building a custom layout, confirm your drive ESC has a BEC output before ordering. If you’d prefer a weapon ESC with an integrated BEC, take a look at the Flycolor Francy 2 30A or Flycolor Francy 2 50A — both carry their own BEC and are well suited for antweight and beetleweight builds.
