Helion Criterion HLNA0302, Owner'S Manual

HRS-3.1 CONNECTION AND CONFIGURATION...

6

Receiver, ESC and Servo Connections:

1.  Channel 1: Steering Servo
2.  Channel 2: ESC (Throttle/Brake)

Note: An easy way to remember this is 1 to turn, 2 to burn 
( as in burn-out ).

Digital Trim Settings:

•  Steering Trim

 › Press the “ST+” or “ST-“ button to adjust the 

neutral position of the steering.  A long “beep” will 
sound

 › Once the trim setting reaches the limit, a long 

steady “beep” will sound

» Depending on your servo configuration, 

“ST+” or “ST-“ will move the servo either left 
or right.  Use either “ST+” or ST-“ to ensure 
the vehicle can track straight with no steering input

•  Throttle Trim

 › Press the “TH+” or “TH-“ button to adjust the neutral position of the throttle.  A long beep will sound
 › Once the value reaches the limit, a long steady “beep” will sound

» The throttle should be trimmed so the vehicle is stationary when no throttle input is applied

Channel Reverse (REV):

The channel reverse function reverses the direction of operation of the servos or ESC’s relative to the transmitter steering and 
throttle inputs. This function would be used if, for example, turning the transmitter steering wheel right resulted in the model turning 
left and vice versa. Some ESC’s require that the throttle channel be reversed in order to program them properly.

NOTE: AS A SAFETY PRECAUTION, PERFORM THE CHANNEL REVERSE ADJUSTMENTS WITH THE MOTOR UNPLUGGED FROM 
THE ESC (CAUTION: DO NOT ALLOW THE WIRES TO TOUCH AFTER BEING DISCONNECTED WHILE PERFORMING THIS SETUP 
PROCEDURE) AND THE WHEELS OFF THE GROUND.

•  Steering Reverse:

 › Turn the steering wheel completely to the left (or right) and press the “REV” button for at least 2 seconds to reverse the 

Steering (ST) channel.

 › The transmitter will beep once for confirmation of “Normal” and twice for confirmation of “Reverse” setting.

•  Throttle Reverse:

 › Pull the throttle trigger completely to full throttle (or push forward for full brake) and press the “REV” button for at least 2 

seconds to reverse the Throttle (TH) channel.

 › The transmitter will beep once for confirmation of “Normal” and twice for confirmation of “Reverse” setting.

Steering Dual-Rate (ST D/R):

Steering dual-rate allows on-the-fly end point adjustments to both sides (left and right) of the steering servo.

•  The default value is 100% of the maximum servo travel. The dual-rate can be set from 20% to 100%.

 › To increase the dual-rate, press the “DR+” button.
 › To decrease the dual-rate, press the “DR-“ button.

End Point Adjustment:

•  Steering End Point Adjustment (EPA)

 › Use this function to adjust the left and/or right steering angle relative to the steering wheel position.

›

CAUTION:  BE CAREFUL TO NOT OVER-EXTEND THE STEERING THROW AS IT CAN CAUSE YOUR SERVO TO OVER-WORK 
AND OVER-HEAT.

 › Steering-Left Side Adjustment:

» Turn the steering wheel completely to the left and use the “ST+” or “ST-“ buttons to adjust the steering angle to the 

desired location.

 › Steering-Right Side Adjustment:

» Turn the steering wheel completely to the right and use the “ST+” or “ST-“ buttons to adjust the steering angle to the 

desired location.

• Throttle and Brake End Point Adjustment (EPA)

 › Use this function to adjust throttle and brake travel adjustments.
