Features:
1. Accurate head-locked feature, helicopter won't quiver or swing away no matter in hovering or pull-up situation.
2. Excellent anti-interference capability.
3. Figure out equilibrium value for gyro automatically when power on.
4. Easy to fly, it only takes little time for a beginner to learn hovering helicopter.
5. Excellent safe capability, helicopter with this 4in1 mixer won't start the motor if there is no stable transmitter
signal.
6. Low-voltage flight, 4in1 mixer works normally when the battery voltage is down to 4.5V.
7.Strong power, enhanced power drive, it helps the helicopter get a long time flight.
The 4-in-1 mixer's temperature rises very little while the motor gets a high temperature with running.
8.Far distance signal receiving, it can receive the signal well from the transmitter no matter
how the antenna is placed. |
