Other Adjustments
Dual Rate
This is used to add or subtract how far the tail blades defl ect. Using
dual rates one can have two (or more depending on the transmitter’s
programming options) rate settings: A lower rate for new pilots and
higher rate for more advanced pilots. (NOTE: Although EXPO can
also be used to mimic this, we prefer to only use EXPO to soften or
sharpen the feel of the helicopter’s tail around center stick). Expo
does not reduce or limit the total travel of the servo like Dual Rates.
Exponential (Expo)
Expo might be used to soften the feel of the tail coming off of center
stick. Futaba calls this Negative (-) expo, or it can be used to sharpen
the feel of the tail coming off center stick, positive Expo (+). Most pilots
use some reduction of sensitivity (Negative Expo). Expo can add to
the smoothness of your fl ight or allow extreme pirouette rates yet
still have an “easy” to fl y tail in and around center stick.
Trouble Shooting Guide
The gyro indicator LED does not come on.
Check to see you have the gyro wires plugged into the appropriate
sockets and that the polarity is correct.
After liftoff , the helicopter abruptly spins out of control.
First check to make sure the servo’s direction is correct by checking
the stick movement to the tail blades, like we mentioned in the setup
part of this manual – OR- It is likely you have the DIR switch in the
wrong position. Re-check the compensation direction.
After liftoff , the helicopter’s tail control is slow to react.
Check for any binding. Also check to see if you have the transmitter’s
dual rates set too low or gyro’s LIMIT dial set too low.
After lift off the tail wiggles back and forth.
Reduce the gain.
The rudder trim constantly changes in fl ight.
First check for binding, then check to make sure you have the rudder
trim at zero as well as channel four’s (Futaba) sub trim centered in
the programming.
In fl ight the tail of the helicopter rotates too fast for me: Reduce the
dual rates or add a touch of EXPO to soften the tail.
