Gyro component names and axial direction
When the rear slides to the left when cornering to the right, the steering and throttle gyros react and
automatically apply counter steer and reduce throttle output to prevent slide.
The KRG-331 receiver features a built-in gyro equipped with KSS (Kyosho Stability System) that allows
stable control on slippery roads. Traction correction function maintains straight lines on uneven road
surfaces and prevents spinouts to allow faster acceleration through corners. The degree of correction
can be adjusted to the driver’s preference and also to suit dierent road surface conditions and vehicles.

Before operating, make sure to setup the failsafe.
WARNING
* Failsafe position is not set at time of shipment.
Gently pull the throttle trigger so the tires rotate and using your hand, shake the car from side to side.
As the tires stop or move, you can conrm if the throttle gyro is working properly.
(If not functioning properly, check the gain adjustment on or the ON / OFF setting of the gyro
function on .)

Shake the car body from side to side without touching the steering wheel. If the front tires
automatically counter steer, the steering gyro is working normally. (If it does not work properly,
check steering servo operating direction setting on .)
Make sure the tires automatically steer to the right when the vehicle is turned to the left, and then tires
steer to the left when the vehicle is turned to the right.

Turn the volume all the way to the right for maximum gain (100). If
you turn it all the way to the left, the gain will be 0 and gyro correction
will not function.
First, set the gain to 0 and drive to adjust the trim.
Reduce the gain if the steering servo vibrates (hunting) or you feel that
the throttle response is not eective.
If the car is oversteering, increase the gain. And if the car is understeering,
decrease the gain.

Fail Safe
The KRG-331 receiver features a fail safe function for extra safety. For GP cars, after all R/C
system adjustments have been completed, move the throttle trigger on the transmitter to
full brake position and push the ‘Fail Safe set’ button. For ESCs with reverse function on EP
cars, move the throttle trigger to neutral and for ESCs without reverse, move the throttle
trigger to full brake, and set by pushing the ‘Fail Safe set’ button. With the Fail Safe setting,
if your model fails to respond to the transmitter signal, the throttle will return to neutral
and not lose control. Fail safe function is disabled by factory default.
