My Drone

March 15,2018

Recently I have assembled and build my first drone. I am trying to share my experience with that build in this blog. I have used following parts to complete the assembly.
  • 330mm quad frame (4 colored arms) – built on quality glass fiber and polyamide nylon,
  • Mount plates along with 330mm quad frame
  • 4 numbers of 1000KV brushless motors
  • 4 numbers of 30A ESA (electronic speed controllers)
  • Two pairs of propellers (clockwise and anti-clockwise) – 10 x 4.5
  • 7.4V-11.1V Li-PO battery charger
  • 11.1V 25C 2200mAh LiPO battery (3 cells)
  • 6” cable ties
  • 6 Channel RF transmitter and receiver
  • KK2.1.5 Multirotor LCD flight controller
  • 2 servo motors for camera controls
  • 4 landing legs for drone
  • 2 axis special nylon PAN/Tilt anti vibration modules for servo
  • Glue gun and glue sticks
  • Soldering station
  • Bolts & Nuts
  • In this drone I have both mechanical & electrical assemblies, I have completed mechanical part first followed by electrical part.

    Mechanical assembly steps:

  • Mount 4 numbers of 1000KV brushless motors in individual arms of 330mm quad frames
  • Properly connect individual 30A ESA with individual motors (connection should be done in such a way that 1 & 3 motors should run clockwise and 2&4 motors will run anti-clockwise)
  • Connect 1045R propeller series with clockwise motors and 1045 propeller series with anti-clockwise motors
  • Electrical assembly steps:

  •  Connect battery output with KK2.1.5 module
  •  Connect ESCs with KK2.1.5
  •  Connect Motors with ESCs
  •  Connect ESCs also with power
  •  Connect RF Receiver’s Aileron to Channel 1
  •  Connect RF Receiver’s Elevator to Channel 2
  •  Connect RF Receiver’s Throttle to Channel 3
  •  Connect RF Receiver’s Rudder to Channel 4
  •  Connect servo1 to RF Receiver’s Channel 5
  •  Connect servo2 to RF Receiver’s Channel 6
  •  Connect buzzer to KK2.1.5 for low battery signals
  • Configure KK 2.1.5 flight controller

  • Complete firmware upgrade to latest one
  • Reset the board using Factory reset option
  • Turn on to Self-control level to auto mode
  • Load motor layout to X – quad, I have used – board offset -45
  • Perform receiver test - Use the transmitter trims to set the Roll, Pitch and Yaw values to zero.
  • Complete all required Misc. setups for KK2.1.5
  • Calibrate ACC (Accelerometer)
  • Perform stick scaling
  • Perform all sensor tests (e.g. gyroscope)
  • Now calibrate ESCs (very important steps, please check all motors should start same time after calibration)
  • Now Arm the quadcopter using throttle
  • Start and test after arming
  • Move & shake Drone and see motor speed changes in Self Mode
  • Tune PID gains
  • My PID setup values (for AIL/ELE - p gain 50, p limit 35, i gain 30, i limit 25) and for (RUD p gain 65, p limit 20, i gain 40, i limit 10)
  • Currently my drone can fly and can capture images/videos. I can maneuver camera using servo channels (2 channels – 5 & 6), but in future, I am planning to use drone for some other purposes, stay tune for future use cases.
  • Please note: in India, you need special permission to fly drone – please read rules & regulations before fly. I have tested this in indoor place only. My drone cost is approx 10K inr and weight 1kg.
