Basic setting with helicopter

This guideline is intended to help you set up a basic (H-1) heli, to get acquainted with the radio, to give you a jump start on using your new radio, and to give you some ideas and direction on how to do even more with this powerful system than you may have already considered.

Briefly, the typical helicopter's controls are as follows:

• Aileron: Changes cyclic lateral (roll). Roll the helicopter. Tilt the swash plate to the left or right CH1.

• Elevator: Changes cyclic pitch. Change the helicopterЎЇs angle of attack (nose up or nose down). Tilt the entire Swash plate fore and aft. CH2.

• Rudder: Change the angle of the tail rotor and yaw the helicopter left or right. CH4.

• Collective Pitch: Adjusts main rotor collective [angle of the paddles], changing the main bladesЎЇ pitch. Increased collective pitch (with throttle) causes the helicopter to rise. Moves in conjunction with throttle on the THROTTLE STICK. CH6.

• Throttle: Open/close carburetor. Move in conjunction with collective pitch on the THROTTLE STICK. CH3.

• REVO: mix that adds rudder in conjunction with pitch. This helps compensate for rotation of the helicopter caused by the increased engine torque. (Never use revo. mixing with a heading0hold/AVCS gyro; the gyro already does this.)

Goals	Steps	Inputs
Prepare your helicopter.	Install all servos, switches, receiver per your model's instructions. Set all trims, dials and sliders to neutral. Confirm all control linkages are 90 degrees (or per instructions) from the servo horn to the ball link for proper geometry and that no slop is present. Mechanically adjust all linkages to get as close as possible to proper control throws and minimize binding prior to radio set up.
Select proper mode type for your model. Ex:HELI H-1	In the BASIC menu,find PARAMETER.	for 1s to BASIC.(If ADVANCE again). to PARAMETER,PUSH
Go to MODEL TYPE.	to MODEL TYPE,then to TYPE.
Select proper mode type. Ex:HELI H-1. Confirm the change. Close.	to HELICOPTER. for 1 sec. Ў®Are you sure?ЎЇdisplays Ј to SWASH , to H-1 for 1sec,ЎЇAre you sure?ЎЇdisplays. to confirm.
Then, NAME the model.	In the BASIC menu, find PARAMETER.	to MODEL SEL.
Go to MODEL SEL.-NAME	to Name(1^st character is highlighted)
Input name.	to change the first character.
Close the submenu when done.	When proper character is display. to next. Repeat.

 

Goals	Steps	Inputs
Reverse servos as needed for proper control operation.Ex: Left Rudder Stick results in leading edges of tail rotor blades moving left.Reverse to operate properly.	In BASIC menu, open Reverse.	for 1s to BASIC.(If ADVANCE again). to REVERSE,
Choose desired servo and reverse its direction of travel. Ex: reverse rudder servo.	to CH4:RUDD Ј to REV is highlighted. Ў®Are you sure?ЎЇ displays for 1 sec.
Adjust travels as needed to match modelЎЇs recommemded throws.(usually listed as high rates.	In BASIC menu, choose END POINT.	to END POINT to choose end point.
Adjust the servoЎЇs end points. (Ex: elevator servo). Return to BASIC menu.	to ELEV. Elevator Stick Ј until up travel is as desired. Elevator Stick Ј until down travel is as desired. Repeat as needed.
Activate THR-CUT.	Open THROTTLE-CUT function.	to THR CUT
Activate the function. Choose desired switch and position to activate.	to MIX, Ј to OFF to SW Ј to SwC, to POSI Ј to DOWN,
With THROTTLE STICK at idle, adjust the rate until the engine consistently shuts off, but throttle linkage is not binding.Close	SwC to down positionЈ Throttle Stick Јto RATE Ј until shuts off.
Set up throttle curve for normal. (Usually changes will not need to be made prior to first flight.Ј©	Open the THR-CURV/NOR function. Adjust if needed. Close the function.	to THR-CURVE ЈCOND:NORMЈ to point 1> Ј to 5%, . Move to next. Repeat.
Set up collective pitch curve for normal as base of -4, center of +5,end of +8 to +10 degrees of blade pitch for aerobatics.2 (If just learning to fly, ask your instructor.)	Open the PIT-CURV/NOR function. Adjust each point to desired Curve.ЈЁEx:first Point:8%Ј© Close the function.	to PIT-CURVE ЈCOND:NORMЈ to point 1> Ј to 8%, , to next point. Repeat.
Set up revo. mixing for normal. (For heading-hold gyros, inhibit revo.)	Open the REVO./NOR function. Adjust to your desired starting point. (Ex: 10%.) Close the function.	to REVO.MIX ЈCOND:NORMЈ to point 1> Ј to 10%, , to next point. Repeat.
Confirm gyro direction.	With radio on, move helicopterЎЇs tail to the right by hand. The gyro should give right rudder input (leading edge of the tail rotor blades move left). If the gyro gives the opposite input, reverse direction on the gyro unit itself.

 

 

Goals	Steps	Inputs
Learn how to operate HOVERING PITCH and HOVERING THROTTLE	Notice at half throttle, the VR(B) dial adjusts the throttle separately from the pitch. VR(A) adjusts the pitch separately from the throttle.	for 1s to BASIC.(If ADVANCE again). to SERVO ЎЈ Throttle stick to center VR (B)Ј VR (A)ЎЈ
Be sure to follow your modelЎЇs instructions for preflight checks, blade tracking,ect. Never assume a set of blades are properly balanced and will track without checking.
Check receiver battery voltage! Always check voltage with a voltmeter prior to each and every engine start.(Never assume being plugged in all night means your radio gear is ready to fly).Insufficient charge,binding servo linkages,and other problems can result in a dangerous crash with the possibility of injury to yourself, others and property.
Confirm the swashplate is level at 0 travel. Adjust arms if needed.
Apply full collective and check that the swashplate remained level and there is no binding. Repeat for full cyclic pitch and roll. If not, adjust as needed to correct in END POINT:
Important note: prior to setting up throttle hold, idle-ups, offsets, etc, be sure to get your normal condition operating properly. Checking setup prior to going airborne: Check voltage! Then, with the assistance of an instructor, and having completed all range checks, etc, gradually apply throttle until the helicopter becomes Ў°light on the skids.Ў± Adjust trims as needed to correct for any roll, pitch, or yaw tendencies. If the tail Ў°wags,Ў± the gyro gain is too high. Decrease gyro gain.

 

1. Periodically move the throttle stick to full and back down to ensure proper servo settings.

2. It is critical that dials A and C be centered when the pitch and throttle curves are setup.
