FPV Mini quad racer

A couple of weeks ago i had a walk in the park and ran into two guys who where flying mini quads on a field with a lot of tree’s and obstacles. I found it quite impressive and I could not resist the urge to have a talk with them to check out the hardware they where using. To make an impression of what they where doing check out the youtube movie they made with a Go-Pro on one of the quads: I take no credit for this insane flying. This is one of the guys i met at the park! I had the opportunity to watch his flying with a second pair of FPV glasses. This made me very enthusiastic to get started with FPV flying myself. And i ordered myself a 250 frame from


This is the unbuild frame with the motors and BESC. Below you will find a build report of the 250 mini-frame and the soldering of the BECS to the integrated circuit board.


I am using Multistar brushless motors and 12a afro BECS for this project. This was a set bought together.

Al the frame parts in the kit and the integrated power distribution board where i will be soldering the ESC’s on. But lets start with building the frame to get an impression of the spots and spaces where all the electronics will be placed. The pictures are quite self explaining so enjoy the ride.

Putting everything together with the esc’s soldered on. And ready to mount on the Naze32 flightcontroller, the receiver and the FPV circuit board.


My first quad-copter!

Posted: 22 May 2015 in Quadcopter

Last year i was getting interested in quad-copters and the potential of those cool flying things! Starting to read about them made me decide to try and build one myself. And i started to search the internet for parts and how-to’s to build them.

Back then the quad-copters weren’t that popular yet and self build quads where the way to go if you where capable of basic soldering and following tutorials that is. I also wanted to make my first build as cheap as possible. That in mind i started to browse Chinese websites for quad-copter parts and electronics. And i managed to gather all the vital parts:

  • X525 frame
  • A2212/13T 1000kv motors (4x)
  • 1 x KK board 5.0 (better get the KK 2.1.5 with LCD Display)
  • 30a speed controllers (4x)
  • 3300mah 3 cell battery
  • IMAX B6 50W 5A Charger/Discharger 1-6 Cells
  • HXT Simple Lipoly Monitor 2S~3S
  • Turnigy 9x transmitter and reciever
  • Propellers (1045 CCW 2x & CW 2x) (Counter clockwise & Clockwise)


X525 Frame, motors, BECS and flight controller all bought from dealextreme. As a starter kit this has good value for its money. I would also suggest to buy additional propellers and spare parts if you are new to this hobby. You probably will crash a lot at the beginning and its a hard wait for spares to arrive from china when you crashed the quad.

Turnigy 9x transmitter. This transmitter has lots of possibilities for the low price. It is flashable with another firmware which brings this transmitter to another level. After that it competes with transmitters in a price range at least 3 to 6 times the price you pay for this transmitter.


This is the finished build of my quad copter. As you could see on this picture the KK multicopter 5.0 board is exchanged for a KK Multicopter 2.1.5 board which has a display on board an is directly tweakable from the board itself.  This makes changing PID controller values much easier and is one of the reasons i exchanged my first flight controller board with this new one. Unfortunately i did built this before i was in the blogging mode resulting in no pictures of the build itself.

Altogether the initial price tag on all this together is around 260 euros. After building and tweaking it do i still say its worth it? Definitely yes, the fun you will be having while building an own quad-copter against the out of the box experience with other of the shelve quads is much bigger. One of the advantages of a self made quad is that if something breaks you will know how to repair it because you have build it. And another cool thing is you will feel like macgyver while building it!
