🌟🎉 New Release! Detrum iStone V3 6-Axis Gyro Stabilizer with Runway Correction 2 in 1 for RC Airplane PWM/S.BUS/DSM Compatible

The Detrum iStone V3 combines V2 and Vector technologies into a single advanced solution. It’s a high-performance 6-axis gyro stabilizer designed for RC aircraft. Featuring advanced flight stabilization, runway correction (ground steering assist), and broad receiver compatibility, it significantly enhances flight stability, control precision, and takeoff/landing performance.

Built around a 32-bit ARM processor and MEMS 6-axis sensor, the iStone V3 delivers real-time corrections across roll, pitch, and yaw axes—making it ideal for both beginner pilots and experienced flyers seeking smoother, more controlled flight.

Compatible with standard fixed-wing, flying wing (delta), and V-tail aircraft, the iStone V3 is a versatile upgrade for nearly any RC airplane setup.

Key Features

Advanced 6-Axis Flight Stabilization

• High-precision MEMS gyro + accelerometer
• Real-time correction on roll, pitch, and yaw axes
• Improves stability, tracking, and wind resistance

Integrated Runway Correction (Ground Steering Assist) Tricycle Gear Optimized

• Automatically maintains directional control during landing and takeoff
• Reduces veering and improves runway tracking
• Dedicated wheel output for nose wheel servo

Four Intelligent Flight Modes

Switch easily via a 3-position transmitter switch:

• Gyro Off Mode – Direct control for setup and testing
• Normal Mode – Stabilized flight with gyro assistance
• Safe Mode (Auto-Level) – Keeps aircraft level; ideal for beginners and recovery
• 3D Lock Mode (Aerobatic) – Locks aircraft attitude when sticks are centered

Wide Receiver Compatibility

Supports multiple receiver types:

• PWM receivers
• S.Bus receivers
• DSM receivers

Flexible Aircraft Support

• Conventional fixed-wing aircraft
• Flying wing (Delta) with elevon mixing
• V-tail aircraft with integrated mixing

Fully Programmable via Programming Card

• Mounting orientation (4 directions)
• Wing type selection
• Flight mode assignment
• Roll / Pitch offset (level trim)
• Gain tuning (angle gain & rate gain)

What’s Included

Item	Quantity
iStone V3 Stabilizer	1
Double-sided vibration-damping tape	2
3-in-1 signal cable	1
Single signal cables	2
Programming card + USB cable	Optional

Quick Setup Guide
1. Create a new model on your transmitter
2. Assign a 3-position switch for flight modes
3. Install the iStone V3 near the center of gravity (CG)
4. Power on the aircraft on a level surface

• Green LED flashing = calibration in progress
• Do not move the aircraft during this process

5. Configure mounting direction and wing type via programming card
6. In Gyro Off mode, adjust servo centers and endpoints
7. Verify gyro correction directions in Normal mode
8. Fine-tune gains and proceed to flight testing

Flight Modes

Installation Guidelines

• Install near the aircraft’s center of gravity
• Ensure arrow faces forward (nose direction)
• Align unit parallel to roll and pitch axes
• Use included vibration-damping tape only
• Keep away from motor, ESC, battery, and moving parts
• Maintain proper antenna and wiring routing

Level Calibration (Important)

If the aircraft does not maintain level flight:

• 1. Land and place on a perfectly level surface
• 2. Toggle the mode switch more than 5 times
• 3. Green LED will flash rapidly during calibration
• 4. Restart the stabilizer after completion
