Thnx for ur note on picaxe, but I just use it to send throttle sigs. In a tethered environment, I will send a low speed to all motors, and visually adjust 4 equal speeds. Then I will increase speed for a minimal ascent. So I am an experimenter.
thnx for the advice on the FCB. I started by just a test board for an ESC and brushless motor. Now I'm looking more at the entire QUAD.
My most recent insight is feeding my PICAXE micro-controller directly to 4 esc/motor combos. This wud just be for limited preliminary tests.
