JJRC H36 Alternative manual

The JJRC H36 is a very nice and capable quadcopter. Unfortunately I found the English translation of the manual provided with it very poor, confusing and full of mistakes. This is why I am proposing this alternative manual.


Switch the quad-copter and the remote on. The lights on the quand-copter are flashing. Move stick S1 all the way down, then up, then down. The flashing should stop and both are paired.


Move S1 up/down to vary the thrust.
Move S1 left/right to make it rotate.
Move S2 to make it move in different directions
The front of the quad-copter has blue LEDs, the back has red LEDS.


There are 2 steering modes: non-headless (default) and headless.
Use F2 to switch between the two.

Non-Headless mode (default)

Non-headless mode is the traditional steering mode, where directions are relative to the craft. Move S2 up/down to make it move forward/backwards relative to its front (blue) and back (red), and left/right for sideway movements.

Headless mode

In headless mode directions controlled by S2 are relative to the orientation of the craft when it was calibrated (see below) regardless of any rotation it has incurred since calibration.

There are various reasons why this mode might be easier:

  • it can sometimes be hard to see properly where is the front and the back is
  • you might want to make it spin quicky (S1 left/right) for fun and it is impossible to steer it according to the directions it is pointing to
  • if you want to make the craft go to your left in non-headless mode you have to push S2 to the left if the craft is facing to the same direction than you, but to the right if it is facing to the opposite direction than you. This requires quick thinking and can be confusing.

It is often noted that in headless mode the directions given to S2 are translated to moves relative to you. This is not completely true. They are translated to moves relative to the direction the craft was pointing to when calibrated. Still, if you fly it far enough from you and always roughly in the same direction this is almost true. If you make it go around you it clearly is not.


Calibration is meant to give a reference position to the 6-axis sensors of the craft. To calibrate, put the craft on an horizontal surface (important) push the throttle to zero (S1 down) and hold S2 in diagonal down & left for about 1 second. Lights flash quickly for less than a second to indicate that calibration is done.

In non-headless mode this is means to give the craft a reference of what horizontal is, and it will maintain this angle when S2 is left in neutral position.

In headless mode it also serves to define the direction to which the craft will go when pushing S2 up. That direction will be when the craft is pointing to when calibrating.

Note that headless and non-headless mode retain their separate calibration parameters, so if you switch modes using F2 you need to re-calibrate.

Novice/Expert mode

Press P1 to switch between novice (default) and expert mode. In novice mode moving S1 and S2 produce less effect (make it turn less) on the craft than in expert mode. This is meant to reduce the negative impact of clumsy abrupt moves but it also greatly reduces manoeuvrability, which is why I find expert mode easier to deal with.
