Foldable tricopter

This project of a tricopter was derived from an existing one called Brocopter. I advise you to have a look at this drone before. You can find all the instructions, CAD files and videos of the original at this link : http://www.thingiverse.com/thing:413639
So at the beginning, my idea was to build a drone as cheap as possible and which could be easy to build and then to carry. That’s why I decided to make this foldable version of a drone. But in order to save some money, I’ve made some modifications which are the following ones :
- First, I replaced the carbon plates by wooden plates. That’s cheaper and can be directly cut with a lasercut machine.
- I updated the CAD models of the motor’supports.
- I changed the ESC case (because I wanted to fit my cheaper ESC in this drone)
The result is a drone which is a bit heavier but it remains solid and cheaper.
