Tricopter Build and videos

So last summer, I decided to build me a tricopter - David Windestal style. The main reason behind it was becuase I was going to be working on a multi-rotor over the coming year as a final year project in my degree at university. 

So here are some photos of the build, and a video or two of progress, crashes and snowboarding uses! 

Here is the finished tricopter: 

Plush 25A ESC's, 

Arduino Mega based flight controller from Aeroquad 

Dt750 motors 

11x4.7 GWS props, also used Gemfans of the same size 

1.6mm Aluminium sheets 

3D printed landing gear 

Turnigy 9x 

3000mAh and 2200 mAh batteries 

All up weight ~ 1kg with battery on board.

Center plate design 

Using 10 mm x 10mm carbon fibre booms 

Here is the completed frame

Battery and camera tray. This needs changing/rebuilding because I used long pieces of wire. This gave the tray a very low stiffness, and causes it to shake at a low frequency when decending / rapid orientation changes. 

Tail assembly with 3D printed landing gear 

 After building it, taking it for a flight was un-nerving and terrifying. Living in quite a windy part of the world did not help either. 

Here are some clips from some flights! 

First video'd flight (2nd flight ever): 

A few flights later... Here is a compilation my grandfather insisted I make... 

And here is the video from on-board the tricopter from a snow trip where I manage to tear my rotator cuff on my first run, hence it contains no chase footage =\ 

And finally heres one with the worst crash I have ever had!  

Cheers for reading!
