This Guide assumes you are using the version 4.5 Quad or Version 1.5 Tricopter software, as developed by Ralf Bauke.
The Basics
Arming/disarming.
The proper sequence for startup is to turn on your radio transmitter first, then power up the controller. at this stage the controller will briefly flash its LED, and is ready, however, the throttle control is not “Armed”
To Arm the controller, make sure the throttle is at Minimum value and the Rudder is all the way to the right, after 2 second the LED on the controller will turn on, this indicates it is ready to fly.
Any aplication of throttle now will cause the motor to turn.
To Disarm , make sure throttle is at minimum and that the rudder is all the way to the left, after 2 seconds, the LED on the controller will turn off, the motors are now dis-armed
Note – when the controller is disarmed, the Yaw servo (Tricopter) also does not respond.
When the controller is armed , slowly advance the throttle, after about a 5-10% movement, the controller will calibrate the GYROS , and start the motors, enables the Yaw servo at the same time.
Set-Up
This guide assumes the ESC’s have been set up correctly
Checking gyro directions:
-Take off the propellers.
-Turn on transmitter and flight controller.
-Set throttle to about 1/4. Motors should start.
-Tilt quad forward. Forward motor should speed up. If not, reverse pitch gyro.
-Tilt quad to the left. Left motor should speed up. If not, reverse roll gyro.
-turn quad CW. Front and back motor should speed up. If not, reverse yaw gyro.
Reversing gyros:
1: Set roll gain pot to zero.
2: Turn on flight controller.
3: LED flashes rapidly 10 times.
4: Move the stick for the gyro you want to reverse.
5: LED will blink continually.
6: Turn off flight controller.
7: If there is more gyros to be reversed, goto step 2, else set roll gain pot back.
Checking transmitter channels:
-Take off the propellers.
-Turn on transmitter and flight controller.
-Set throttle to about 1/4. Motors should start.
-Move pitch (elevator) stick forward. Back motor should speed up. If not, reverse pitch (elevator) channel.
-Move roll (aileron) stick to the left. Right motor should speed up. If not, reverse roll (aileron) channel.
-Move yaw (rudder) stick to the left. Front and back motor should speed up. If not, reverse yaw (rudder) channel.
Initial transmitter ATV/servo range settings:
-pitch (elevator): 50%
-roll (aileron): 50%
-yaw (rudder): 100%
Initial gain pot values is 50%. Increase until it starts to oscillate rapidly, then back of until it is stable again. Fast forward flight needs lower gain.
Too low gain is recognized by hard to control and/or always want to tip over.
Final check:
Hold the quad firmly over our head, give about 1/2 throttle slowly. Hold it steady when you start increasing the throttle, becouse it calibrates its gyros when throttle leaves zero, and then the gyros need to be at rest.
If it tries to twist away, check propeller and motor directions, gyro placement and trim settings. A slight twist is OK.
If not, try to twist the quad. It should resist your movements. And also more gain gives more resistance. If it starts to oscillate, reduce the gain. If you
need to reduce the gain below 40%, something might be wrong.
Note: the correct procedure for taking off from the ground is as following:
1: The quad and its propellers needs to be motionless.
2: Increase the throttle (collective). Just as the throttle leaves zero, gyro calibration is performed.
3: Enjoy! And remember to close the throttle if you lose control. Much less damage
