BOCO RC - Berserker 74KG 25T Steel Gear Servo

Big power. Big reliability. 1000oz-in of unstoppable-ness.

WP (IP67) · STL · BL

WHAT IT IS
A 25T spline, IP67-waterproof, steel-gear brushless servo engineered 
for big-power, big-tire builds and heavy rigs — the abuse-tier  servo in the BOCO lineup.

IDEAL FOR
- Heavy rigs and big wheel/tire combos
- Rock bouncers and aggressive crawlers
- Builds that need to wiggle a heavy nose down

WHY YOU WANT IT
When you need big power and all the reliability, you need the 
Berserker. Engineered to take a serious beating. With right at 
1028oz-in of torque this servo can handle big wheel and tire combos 
or wiggle a heavy rig nose down. Thick 416 stainless gears, high 
chrome shafts, full aluminum CNC case, and quad ball bearings come 
together to make a stout servo designed for abuse. Same lineage and 
warranty as the Persuader — just bigger.

POWER REQUIREMENTS
- Operating Voltage: 4.8V - 8.4V
- Power Source: Standard receiver power
- BEC Required: A good BEC is required to fully utilize this servo 
  (~7A draw fully loaded)
- ESC Notes: Mamba X, Monster X, and certain Hobbywings will run 
  it fine. 1080 and weak RTR ESCs may brownout and underperform — 
  check your ESC's BEC spec before buying. A "glitch buster" 
  capacitor can help, but a strong BEC is the most effective solution.

INSTALLATION NOTES
A strong BEC is the most effective way to get full performance — 
weak BEC systems will brownout under load. If you submarine your 
rig for extended periods, remove the bottom plate and let the servo 
air dry just in case. Frequent brownouts can damage electronics and will not be covered under warranty.  Need some juice for big power.
