GY401 is a high-performance, compact, lightweight AVCS (Angular Vector Control System) gyro developed for model helicopters. Because the sensor and control circuit are integrated, it is simple to install.
The Futaba GY401 is a high-performance, compact, and lightweight AVCS (Angular Vector Control System) gyro designed for model helicopters. It features an integrated SMM (Silicon Micro Machine) gyro sensor and a conductive resin case to reduce size, weight, and electromagnetic interference. The device automatically cancels rudder trim changes caused by wind and attitude shifts, allowing for stable flight without manual trimming.
| Dimensions | 27 x 27 x 20mm |
|---|---|
| Weight | 27g (including connector) |
| Operating voltage | +4 to +6VDC |
| Operating temperature range | -10°C to +45°C |
| Control system | Digital advanced PI control |
| Gyro sensor type | SMM (Silicon Micro Machine) system vibration gyro |
When the gyro power is turned on, the transmitter rudder signal automatically received at that time is assumed to be the neutral signal and is memorized.
The gyro should be installed at least 10cm from the drive motor to avoid electromagnetic noise interference.
No, the DS switch should only be set to ON when using Futaba digital servos; using it with other servos may destroy them.
