byBy chance iI read this patented method to control the rotor pitch without a swash plate usually a helicopter, by adding two parallel hinges on each blade root, when. When add torchtorque to spin it the pitch would change so you can generate a vector force against the rotor axis:

This is a very useful control technique for control a miniature in doorindoor drone, although itsit's patented (https://www.google.ch/patents/WO2014160526A3?cl=en i). I still want to try it at home by building an ESC (hobby model naming for brushless motor contrllercontroller).
aA good starting place maybemay be to buy a cheap TI FOC InstalSPIN controller demo board by hacking some code on: http://www.ti.com/tool/launchxl-f28027f with a driver board to drive a 2213 dji phantom motor.
theThe question is:
- I don't have any experience, would this board/code base could implement this function directly?
- ifIf not, any starting point for other FOC controller will do
iI want to make a ESC with 3 120 angled position input to tell the motor controller where iI want the positive pitch to go.
Thanks.
