Hi,

I'm Adrian from Hungary/Europe. Let me introduce my tricopter project.

My goal was to make something really good-looking copter that have ally features I need.The design process started 1 years ago. My first idea was to make a composite chasis, from glass/carbon fiber.I designed the copter in a 3D modelling software, and also designed the necessary moulds for making each parts, here is the initial design:

This is a sample of the mould design:

I also made some FEM calculations, to check the stress dispersion:

Unfortunatelly, this type of production would cost too much for me. I tried to find partners in Hungary, without success. So I almost forgot this project. But some months before I read a lot about 3D printing, and finally I found a great partner in Hungary (many thanks to the Ground Zero Team www.groundzero.hu !!!). So I started to redesign my copter according to the requirements of 3D printing:

Then I sent the .stl files for FDM printing. Here is the result:

This is my current configuration:

• Turnigy SK3-2826-1130 motors
• 8x4,5 karbon SF props
• 10A HK ESC (simonK firmware)
• ArduFlyer 2.5 with ArduCopter 3.0.1 code
• ULOX NEO6-M GPS
• 2000mA 3S lipo (2 db 1000mA 3S2P)
• Flytron 25A ultralight current sensor
• MKS-DS95 servo
• RECOM 5V 1A power supply for electronics
• 3DR 868 MHz telemetry module
• RCTimer OLED screen
• Immersion 600mW 5.8 video TX + Coverleaf antenna
• MinimOSD, with KVTeam code
• KPC-E700PUB camera
• FRSKY Futaba FASST-compatible receiver, PPM
• controlled LED-s and buzzer

All-up weight is 782g, and has 8 minutes of safe flight time with 20-25% of remaining battery.

(Please note that I used Crius AIO Pro at first with MWI code and KV-OSD code. These can be found on the following pictures and in the videos.)

LED sripes are controlled by APM:

Here are some videos:

- UPDATE - 

stl files can be downloaded from here:

And these are the additional metal parts for rear arm control:

I wish you all good luck on reproducing my tri.

Please note that I'll not modify desing according to personal wishes, since my spare time is quite limited and I focus on my personal projects. Thanks for understanding!!!

Best Regards
