Order parts: setup with X525 V3 frame and Hobbyking KK2.0 flight controller board

This article is about building my first quadcopter with X525 V3 frame and Hobbyking KK2.0 flight controller board.

I’ve read about quadcopters and wanted to build one myself.
A few things I had in mind when I was planning the build session and started ordering parts:

  • it has to be cheap
  • made by myself (so not “Almost ready to fly” or “Ready to fly”)
  • easy to handle
  • big, so it would fly more stable then a small quad

In the past I’ve had some experience with RC planes like the Kyosho Calmato and shockflyers. These are retired now, but I still got some RC equipment!
A Graupner MX12 with 2.4Ghz Assan transmitter and receivers, Turnigy Accucell 6 lipo charger and a couple of small parts.

The goal was building it cheap so I could reuse my Graupner and charger. Saves me the first money!

The first thing I had to found out, was which frame I had to buy. You can build one on your own, but because the frames are so extremely cheap, I decided to order one. It had to be light and cheap: the Hobbyking X525 V3!
This frame has a diameter of 60cm, is made out of glass fiber plates and aluminum booms and weighs no more then about 400gram.

I decided to buy one on Hobbyking but unfortunately they where out of stock :( After waiting for more then a month, I looked somewere else and found the exact same frame on AliExpress (later on I explain why this wasn’t such a good idea).
For $23,- including shipping, it came to my house.

The next imported part, probably THE most important part, is the flight controller. One of the beginner favorites is the Hobbyking KK2.0 flight controller board. It is (again) cheap (for $29,- its yours), has the necessary three gyro’s, can fly out of the box and has a very nice feature for beginners: it has a LCD screen with menu buttons! This means that you don’t need a computer to calibrate or tune it. You can do this while you’re on the field while testing your quad!
I’ve read a tutorial on the Dutch Modelbouwforum about a quad with this flight controller board.

Ordered the board on Hobbyking (after a long wait for restock. Has been replaced by version KK2.1 now).
