If you like my project vote for "A Smarter Tricopter - Yuri Tikhonov"


Good day comrades! I am very glad for the opportunity to participate in a Smarter Life Challenge!

The last few years, I am fond of RC models. I already have a wheeled robot, several helicopters and completely DIY micro-quadrocopter. It is time for tricopter!


So, the main features of this project are:

  • Frame construction: Classic tricopter (weight ~0.75kg).
  • "Heart" of tricopter: PSoC 4.
  • BLDC ESC's with custom firmware.
  • FPV with OSD function (optional).
  • Custom Tx system (optional).


You should immediately notice that I live in Russia and the delivery can be a big problem, for this reason, I split the project into two stages (A and B):


Stage A:

  1. Create based on PSoC 4 heart (for tri and quadcopter).
  2. Create Firmware (for tri and quadcopter).
  3. Install "1" and "2" to my old DIY Quadcopter with DC-motors.
  4. Use my Turnigy Tx-system to control it.

Stage B:

  1. Get based on PSoC 4 heart from stage A
  2. Get Firmware from stage A
  3. Create a new DIY Tricoter frame with motors, props etc.
  4. Update firmware on ESC's
  5. Connect all together
  6. Use my Turnigy Tx-system to control it



  1. Get all from stage B
  2. Install FPV and OSD system
  3. Create based on Arduino Esplora (or somthing like this) Tx system


Now I want to:

  1. Receive PSoC 4 develompent board and start to create firmware. As a starting point I want to use open-source project MultiWii 2.0.
  2. Buy all RC-parts on HobbyKing (~200-300$).
  3. Farnell's 500$ I want to use first of all for buying Arduino Esplora, PSoC 4 chips and some instruments.


Update blog I plan to once a week (or more frequently as possible). If you have some interesting ideas - I'll be glad to see it!
