Set the Gear Mesh with the Paper Technique (by MarioIArguello)

Use a piece of paper between the gears to adjust for smooth gear mesh. The piece of paper should pass through the gears, not too tight not too loose, when the gears are rotated.

How to adjust Main Blade/Tail Blade Grip Tightness

Align the blades straight out from the blade holders with the center line of the helicopter and turn the helicopter on it’s side (horizontal to the ground).
The blades should remain straight and aligned while holding the helicopter still. The blades should fall equally when the helicopter is shaken slightly.
If not adjust both blades as needed so the blades remain straight and aligned on it’s side while holding the helicopter still and both fall equally when the helicopter is shaken slightly.
For larger size helicopters a harder shake will be needed to get the blades to fall (pivot down).

How to check and set COG (Center of gravity)

Method 1

Insert the battery and make sure the canopy is on if you will be flying with it.
With the blades straight out and fully extended, face the blades to the right and left of the
canopy looking at it from the back or front and use two index fingers under the blade grips or flybar to lift the helicopter and see how it balances. If the tail dips down it is tail heavy, push the battery forward until it balances.
If the nose dips down it is nose heavy, push the battery backwards until it balances.

Method 2

Insert the battery and make sure the canopy is on if you will be flying with it.
Hold the helicopter sideways by the rotor head with the blades pointing straight up and down (like it’s in a knife-edge orientation).
If the tail dips down it is tail heavy, push the battery forward until it balances.
If the nose dips down it is nose heavy, push the battery backwards until it balances.

 

HELI Mode vs ACRO Mode

  • HELi gives you the option to have throttle hold and flight modes.
  • Some people like to use ACRO instead of HELI because ACRO requires no setup to fly coaxial and fixed pitch helicopters.
  • ACRO and HELI both work well for coaxial and fixed pitch helicopters.

How to remove the Swashplate

Method 1

1. Remove the servo to swash links

2. Remove the landing gear

3. Removed the main gear

4. Pull up on the head on remove the entire assembly from the helicopter

5. Remove the main shaft collar

The swashplate will now slide down and off the main shaft.

 

Method 2

1. Remove any links including the servo to swash links

2. Remove the head button if it has one

3. Remove the rotor head from the main shaft which is held in by a pin or screw (s)

The swashplate will now slide up and off the main shaft.

 

How to remove the Main Shaft

1. Remove the head button if it has one

2. Remove the rotor head pin or screw (s)

3. Remove the main shaft collar

4. Remove the landing gear

5. Removed the main gear

Slide the main shaft up or down to remove it

 

How to remove the main gear

(by Gryffandor)

1. Use a small screw driver to gently pry down on the top of the gear at the main shaft

(by scub)

2. Slide tweezers between gear and frame, pops right out evenly

 

How to remove the Spindle (feathering shaft)

1. Remove the main blades

2. Remove one of the Spindle (feathering shaft) screws

The Spindle (feathering shaft) can now be removed.

 

How to remove the Tail Boom

The tail boom will either be pressed in or held in by a screw near the end of the tail boom
by the frame. If it has a screw loosen up the screw and remove the tail boom.
If the tail boom is pressed in gently pull it out of the frame.

 

Tail Wag

  • Gyro gain set too high
  • Tail rotor blade slipping on the motor shaft
  • Tail rotor blade bent or cracked
  • Teeth missing on the main gear or worn/damaged teeth
  • Pinion mesh too loose
  • Bad solder connection
  • Tail motor needs to be replaced

 

Bent Main Shaft

Symptoms: (by tutelar-rc)

  • Head wobble
  • Helicopter seems difficult to control in a hover, moving around on its own
  • Loss of power

 

Bent Spindle (feathering shaft)

Symptoms: (by tutelar-rc)

  • Main rotor blades no longer track
  • Main rotor pitch is jumpy, seems to change on its own
  • Helicopter seems difficult to control in a hover, moving around on its own
  • Loss of power

 

TBE – (Toilet Bowl Effect)

  • Bent flybar
  • Stiff flybar
  • Bent shaft
  • Ball links binding
  • Ball links too tight

 

Nose pitches up in fast forward flight with a 3 or 6 axis gyro

Receiver gyro gain is too low. Increase the Elevator/Aile gyro trim pot (s).

If the receiver gyro gain is too high the heli may bob up and down.

 

Nose drifts CCW or Helicopter spins CCW

  • Gyro gain is too low
  • Tail rotor blade is loose
  • Cracked or bent tail rotor blade
  • Tail rotor blade is slipping
  • Weak tail motor
  • Missing or damaged teeth on tail gear drive
  • Adjust tail servo, tail servo pull rod (rudder control rod), tail pitch assembly
  • Reverse switch on the tail gyro set wrong
  • Rudder trim not centered
  • Drive belt or drive shaft slipping
  • Tail rotor drive belt is twisted

 

How to set zero degree pitch at mid stick

www.youtube.com/watch?v=PX9UgHfg_NM

The method in the video also works on other Blade helicopters, Walkera helicopters, and other helicopters too.

Make sure your swashplate is level first.
You want the throttle at mid stick and set the blades to have zero degree pitch. Lengthen or shorten the links as needed adjusting all three links equally.

Walkera uses pitch at mid stick to hover in normal mode so you need to use ST-1 or ST-2 to set zero degree pitch at mid stick.
