Building a QuadCopter or MultiCopter

First of all lets get all the terminologies associated with QuadCopters.

What is the difference between RTF, BNF, PNP and ARF ?

  • RTF stands for Ready-to-Fly and it means the model you are buying comes complete with everything you need to get started – straight from the box! Have look at our ready to fly drones.
  • RTR stands for Ready-to-Run and it means that the RC car or boat comes with the transmitter, battery and charger. You can start racing without requiring any extra component.
  • BNF stands for Bind-N-Fly. Bind-N-Fly products come with everything you need except for a transmitter. With BNF products you can use the transmitter of your choice and bind it to the receiver included with the model.
  • PNP stands for Plug-N-Play. Plug-N-Play products come with everything you need except for a transmitter, receiver battery and charger. It does contain servos, motor and ESC.
  • ARF stands for Almost-Ready-to-Fly, this means the model needs some additional “need to complete” items before you can start flying. Common additional items include servo’s, motor, electronics, batteries and even glue.

What are the Components of a quad-copter ?

  • Frame
  • Motors
  • Propellers
  • ESCs
  • Battery
  • Flight Controllers
  • Receiver
  • Remote Control
  • Gimbal

Lets discuss about each of the components needed to build a quadcopter

Frame: Frames mostly designed of glass fiber or carbon fiber making them crash-worthy. There are different types of frame available in market starting from INR 1000/-($13) to INR 6000/- . Most frames come with a set of bolts needed to fix it. You may use quadcopter frame or a hexcopter frame the arms are same if you are using DJI ARF KIT, Only the center PCB shape changes.QWinOut-DIY-24G-6CH-KK-V23-F450-Flamewheel-RC-Quadcopter-4-Axle-UFO-Unassembly-Kit-RTFARF-Basic-Drone-0-6














Motors: Motors come in different varieties with different parameters for speed or RPM (1000KV i.e. 1000 Kilo Rev per second) and the turns of coil like 6T/10T/13T. What voltage it will support is also need to be checked while purchasing motors. Battery mostly support 2S to 4S (4S means 4 lipo cells)4 cells x 3.7v = 14.8v.

Hello, I am Asim admin of this blog. An expert in Scientific Instrumentation (Analytical Instrumentation). My works are always associated with both Physics and electronics. Currently working on ARM based embedded systems for Optical(UV and Visible) and electrochemical spectroscopy (EIS). My M.Tech. Thesis was related to all these things. I had worked for a 8 bit microcontroller based standalone EIS (electrical impedance spectroscopy) device. I have Masters in Instrumentation engineering from NIT Kurukshetra,Haryana and Masters in Electronics Science from Sambalpur University, Odisha (Formerly Orissa/Utkal) Am also work for PHP MySQL AJAX based CMS design. i love blogging and coding(am not an expert).
