Frequently Asked Questions
What is i-BUS2 and do I need a Flysky transmitter to use the GTS Series?
i-BUS2 is Flysky's smart digital protocol that enables two-way communication between your transmitter and the servo. With a compatible Flysky transmitter (NB4 or NB4 Pro), you can remotely adjust servo parameters (stiffness, speed, deadband, center point, direction), monitor real-time voltage and temperature, and log data for up to 1 hour after racing. Note: the NB4 Pro is required for the data logging and monitoring function. In standard PWM mode, the GTS Series works with any conventional RC receiver without i-BUS2 features.
What is the difference between GTS-3, GTS-5, GTS-6, and GTS-7 — which one is right for my car?
All four models share the same i-BUS2 protocol, IP67 waterproof rating, and 7075 + Steel gear train, but differ in torque output, motor type, and physical size. The GTS-3 (30KG, 63g, 41x20x29mm) uses a standard brushless motor and suits 1/10 EP touring, ebuggy, and crawler builds. The GTS-5 (50KG, 63g, same footprint) upgrades to a 4-pole brushless motor for more torque in the same compact body. The GTS-6 (60KG, 78g, 40x20x38.3mm) and GTS-7 (70KG, same size) are larger-bodied servos for 1/8 and 1/5 scale platforms. Choose based on your vehicle scale and torque requirements.
Are the GTS Series servos truly waterproof — what does IP67 mean?
Yes. All GTS Series models carry an IP67 waterproof rating, which means they are fully protected against dust ingress and can withstand immersion in water up to 1 meter deep for up to 30 minutes. This makes them suitable for wet track conditions, rain racing, and off-road use where water and mud exposure is unavoidable.
What high-speed transmitter modes are supported — is it compatible with Futaba and SANWA?
Yes. In addition to Flysky i-BUS2, the GTS Series supports high-speed modes from multiple major brands: Noble NB4 Pro (NOR / SR / SFR), Futaba (NOR / SR / UR), and SANWA (NOR / SHR / SSR / SUR / SXR). It is also compatible with the Power HD PG-CB63 program box for standalone parameter adjustment without a transmitter.
What voltage should I run the GTS Series at, and is it compatible with LiPo batteries?
All GTS models operate on 6.0V to 8.4V DC, making them compatible with 2S LiPo (7.4V) and 2S LiHV (8.4V) battery systems, as well as NiMH packs at 6.0V. Running at 8.4V delivers maximum torque and speed — for example, the GTS-7 reaches 70 kg-cm at 8.4V vs 52 kg-cm at 6.0V. Do not exceed 8.4V to avoid damaging the servo.

Bought this to put in place of the smaller wheel on my NB4+. I have large hands, this bigger wheel allows my movements to be more precise due to larger diameter. Direct fit to an NB4+.
James Robert
Great addition for the Noble
It fits great and looks awesome. I really like the lower mount and it keeps the weight lower when you have a camera attached

Description
Choose the torque your chassis actually needs. The Power HD GTS Series brings four high-voltage brushless RC servos into one clear lineup, from the compact 30kg-cm GTS-3 for fast 1/10 builds to the 70kg-cm GTS-7 for demanding 1/8 and 1/5 steering. Every model supports 6.0–8.4V operation, i-BUS2 smart control and IP67 protection.
In This Guide
Key Features
✅ Four torque levels — Select 30, 50, 60 or 70kg-cm maximum torque to match vehicle scale and steering load.
✅ i-BUS2 smart control — Compatible Flysky systems can support remote parameter adjustment and servo telemetry functions.
✅ IP67 protection — Sealed construction helps protect against dust and water during wet or off-road use.
✅ High-voltage operation — All variants support 6.0–8.4V DC for 2S-compatible RC power systems.
✅ Brushless performance — Brushless motors deliver responsive control; GTS-5, GTS-6 and GTS-7 use 4-pole brushless designs.
✅ Reinforced gear train — 7075 aluminum and steel gears balance weight, strength and impact resistance.
Which GTS Model Should You Choose?
Fitment matters: GTS-3/GTS-5 measure 41 × 20 × 29mm, while GTS-6/GTS-7 use a taller 40 × 20 × 38.3mm body. Measure your servo bay before ordering.

Vehicle & Radio Compatibility
The GTS Series works in standard PWM mode with conventional RC receivers. Its i-BUS2 functions require compatible Flysky equipment. Supported high-speed modes listed by Power HD include Noble NB4 Pro NOR/SR/SFR, Futaba NOR/SR/UR and SANWA NOR/SHR/SSR/SUR/SXR. The series is also compatible with the Power HD PG-CB63 programming card.
Setup Notes
Before installation: Confirm servo dimensions, BEC current capacity and 6.0–8.4V output. Do not exceed 8.4V. Set endpoints carefully to avoid binding, overheating and unnecessary current draw.
Select the model that fits your chassis first, then choose the torque level your steering system needs.
