Futaba GY 401
A gyro is used on a helicopter to help stabilize the tail. Without one you would have to compensate for the variations in torque and undoubtedly this would make heli’ flying a lot harder than it already is.
There are two forms of gyros that are used in helicopters. They are: Heading hold and rate gyros.
Heading hold will fight any movement that is not inputted from your transmitter ie wind gusts.
A rate gyro will not do this.
Most heading hold gyros have two modes: heading hold and rate mode
Both have their advantages and disadvantages.
Heading hold will make hovering a bit easier as it will keep the tail where you want it however when you fly circuits you will have to put tail inputs in as it will try to fight to keep the last input you made. So you could end up sideways or in some other orientation.
The rate mode will allow the tail to gently weathercock around in circuits but you will have to fly the tail when doing sideways and backwards flying.
Gyros like the GY401 have both modes so you can use heading hold to hover and rate mode for circuits and switch back and forth in flight.
No matter which gyro you decide on a good, high speed tail servo will really make all the difference.
