I have been working on a new miniquad project where I did plan to use VRBrain controller, but now I must redesign it for the new VR Micro Brain :-)



I plan to use:

- 16mm carbon tubes (so I can mount ESC inside the tubes)

- 20A Slim Afro ESC

- SunnySky 2204s 2300Kv motors

- HQ Prop 6x3 Carbon Composit Props (some info on the motor/prop combo)

- VR Micro Brain :-)  + GPS +…

Did some simple test in my garden + alt hold, loter and auto land - no probles, and wery stable.

My great VRBrain controller is running code from today (10.10.2013)  (used Eclipse to pull and build the latest code from Emilie, that does an impressive…

Almost done :-)

I do not use bullet connectors on the ESC to motor cables, so I connect the cables like this while testing.

First, I test if the rotation directions are correct, by connecting the “servo” cable to the throttle channel on my rx. If the rotation direction is wrong, I swap two of the three cables between ESC and motor.

My ESC`s are flashed with SimonK, so before I disconnect the RX, I calibrate the ESC. Disconnect LiPo,…

I found that I had to do some changes to fit the controller.

In this image I have used 10mm spacers between the center plates - I may test other lengths -…
