GT3s V2 Brushless Servo
Efficiency meets raw power—compact and ready to rip.

Overview:
A refined GT3 upgrade, the GT3s V2 offers optimized motor and gear efficiency in a slightly lighter, more compact package. Same waterproof specs and lifetime gear backing, tuned for serious trail use where weight matters.

Why It Shifts Ahead:

• 📉 Improved Efficiency with updated brushless motor and gearing

• ⚖️ Higher Torque per Weight – 639 oz‑in @ 6V, 736 oz‑in @ 7.4V, 834 oz‑in @ 8.4V

• 🚀 Snappy Response – 0.132 s @ 6V, 0.105 s @ 7.4V, 0.100 s @ 8.4V

• 🧰 Steel Gears & 4‑Pole Motor – smooth durability

• 🌧️ IP67 Waterproof, same rugged reliability

• 🔁 Lifetime Gear Warranty (1 Year on electronics)

Tech Specs:

• Voltage: ≤ 8.4 V (CASTLE BEC 2.0 OR PRO REQUIRED) Using other brands or models void warranty 

• SET ENDPOINTS
• Size: 40.8 × 20.2 × 29.5 mm

• Weight: ~66 g

• Requires 25‑tooth spline horn

Ideal For: Lightweight trail racers and crawler setups prioritizing responsiveness without sacrificing strength.

Shift RCS – Power Requirements & Warranty Policy

All Shift RCS high-performance digital servos are engineered to operate within specific voltage and amperage requirements. Proper power delivery is critical to the safe operation and longevity of the servo.

Power System Requirement

Shift RCS servos must be powered by a properly rated external BEC capable of supplying stable voltage and sufficient continuous and peak amperage. As stated in the product description, Shift RCS specifies the Castle BEC 2.0 for approved operation.

Use of Underpowered Power Systems

Use of an underpowered BEC, receiver-powered setup, or any power system unable to meet the servo’s current demand places the servo outside of its designed operating parameters.

When adequate amperage is not available:

Voltage drops under load

The motor enters partial stall conditions

Internal electrical resistance increases

Excess heat is generated

Internal electronic components and motor windings may be permanently damaged

This type of damage is the result of improper power supply, not a manufacturing defect.

Warranty Coverage

Failures caused by insufficient amperage, voltage sag, or improper power delivery are not covered under warranty and may void warranty eligibility.

Examples of non-warranty conditions include, but are not limited to:

Use of an underpowered or non-approved BEC

Receiver-powered servo operation

Evidence of thermal damage due to current starvation

Operation outside published voltage and amperage specifications

Evaluation & Customer Support

While these conditions fall outside standard warranty coverage, Shift RCS stands behind its customers. Customers may submit a warranty request through our website along with proof of purchase. Upon inspection, we will determine whether the servo can be repaired or whether alternative assistance may be offered at our discretion.
