If you’re pushing the limits of large-scale RC driving, you need electronics that can keep up. The 1-5 Beast PRO 300A 8S G2 BLE by ZTW is exactly that: a next-generation ESC built without compromise for demanding 1:5-scale vehicles.
Raw Power Where It Counts
With a continuous current of 300 A and a staggering peak of 1800 A, the Beast PRO holds its ground even under extreme conditions. Support for 3–8S LiPo input gives you full flexibility across different battery setups — from a solid entry-level pack to a high-voltage race configuration.
The robust aluminum housing doubles as an efficient heat sink, a critical advantage during sustained full-throttle runs where thermal management can make or break a session.
Wireless Setup via Bluetooth
Gone are the days of fumbling with programming cards. The G2 BLE connects directly to an Android or iOS app via Bluetooth Low Energy, letting you fine-tune every parameter from your phone — fast, intuitive, no extra hardware needed.
Add firmware upgrade support to the mix, and you’ve got an ESC that stays current long after purchase.
Dual-Voltage BEC
The onboard BEC delivers up to 10 A and is switchable between 6.0 V and 7.4 V — covering everything from standard servos to high-voltage systems that demand precise, high-torque steering response.
