Small, sexy, and quick. Low-profile, 4S, waterproof.

WP (IP67) · STL · BL · LP (Low Profile) · DP (Direct Power)

WHAT IT IS
A 25T spline, IP67-waterproof, low-profile direct-power servo built 
for lightweight rigs and high speed — 4S compatible with brushless 
motor and stainless gears. Can be programmed as a Servo Winch before shipping.

IDEAL FOR
- Lightweight crawlers and trail rigs
- High-speed rock racers and low riders
- 4S direct-power builds where space is tight

WHY YOU WANT IT
When I designed the Lil Spinner I had lightweight rigs and high 
speed in mind — it'll wiggle real good on 4S or hop a low rider 
pretty quick. Stainless steel gears, full aluminum case, and a 
brushless motor get the job done over and over. The low-profile 
form factor and direct-power setup let you tuck it into builds 
where a standard-size servo just won't fit. If you've got a 2.2" 
or heavy rig, look at the Persuader or Berserker instead — but for 
race and lightweight builds, the Lil Spinner is the answer.

Direct-power servo — must be powered from a battery balance plug, 
not the receiver. Use the included 3S or 4S adapter to match your 
pack. If you submarine your rig for extended periods, remove the 
bottom cap and let the servo air dry just in case.
