Build a Performance Quadcopter for under £150 – Part 1

With summer fast approaching I decided it was high time I started a new project. I have been toying with the idea of building a quadcopter for a while now. The internet is littered with websites and videos detailing other people’s builds so I decided to give it a go. What will follow hopefully is a number of successive posts detailing my build process. Which should provide enough instruction for other people to build their own.

From the outset I had a fairly rough idea of what I wanted to achieve but for a little more inspiration I started reading a other peoples builds. One if the best builds I found was from a chap named Daniel J. Gonzalez. He based his quadcopter around a 330 mm frame which seemed like a good compromise to me. Click on the picture below to jump directly to the build on his blog.

Like Daniel I opted to use the Hobby King F330 glass fibre frame. For the flight controller I decided on the Hobby King KK2.1.5 based purely on the customer reviews. Apparently the KK is easy to set-up and flies exceptionally well. It may well do with a competent pilot but time will tell how it copes with me in control. The speed controls I chose were the Hobby King blue series controllers. These are a fairly standard controllers however they can be flashed with Simon K’s high performance firmware optimized for quadcopter use. More on this later. The motors were Turnigy 1100kV outrunners which I am hoping should produce more than enough thrust to get the quadcopter off the ground and maybe even enough to carry a GoPro in the future.

Total spend = $114.52 + $8.09 (shipping) = $122.61 which was approximately £89.42 GBP at the time of purchase. All that was required to complete the build would then be a suitable 3S LiPo battery pack and radio system. I hadn’t decided on which radio system to use so opted to leave that until the initial build was complete.

Parts on order so the next post I shall start the build process.
