"R There are a few ESCs that are 6S and have a good governor. http://www.hobbyking.com/hobbyking/store For a little more you can get this 12s…"

"Oh! And great idea mini"

"Yes, R_L, I need to test these controls better but am 1025 miles from home right now and it Will be Tuesday before i get back (awk!)"

"Yes, but the problem is none of the ESC's people are using, creating, and hacking for multi-rotors will work with high voltage.  My heli is 8S, and that's low, most helis run 12S now. That's why I'm designing a more…"

"R If you want to get a real accurate RPM controlling ESC the ESC32 would probably be the way to go. Bill Nesbit said he thought it could work if the PID settings were adjusted for RPM control.  Larry"

"Dan, let me know how that goes with the governor.  Some work well, some don't.  I have a 40A K-force on my little heli, and the governor and soft start work well.  On my big heli, I have a SuperBrain 100A.  The soft-start…"

"Dan  A year ago I ordered a few heli ESC and I found one that worked OK.  Most ESC with RPM control are not very good.  Just test one ESC with a VPP on the motor and you'll be able to hear how well they work. Larry"

"Yes, the rotors turn in the standard quad directions. Two rotors CW and two CCW, opposing rotors the same direction. On my first attempt, I am going to try the governor mode of the ESC's. If that fails will need some pitch/throttle curve…"

"Someone also did one with the Open Copter board. Still searching for that link. "

"Dan, I'm just waiting on some feedback from you.  Be sure to send me a PM if you respond here and I don't see it."

"Dan, I just took a first crack at creating this code. You can see it in my clone here: https://code.google.com/r/robertlefebvre-wip2/source/detail?r=172783aad64c6162138fa60527fa190a0ebf04b3&name=VariablePitchQuad This is not finished.  Do…"

"Direction of rotation is as the standard quad layout?"

"Ken, what do you want to do for motor RPM speed control?  Are you going to use an ESC with a governor?  Or do you just want to run it wide open?  Or you can run a collective-pitch-to-throttle curve."

"Thanks! I will check that out KR."

"@Brad Hughey,   That is a fascinating paper. Especially when pondering future "Avoid" capabilities, the need for which has been mentioned in a recent book...  And I see what you mean by "...the parameters of low…"

"Hi! Very nice project! I don't know if it helps but there is a multiwii version for quads with variable pitch. http://code.google.com/p/multiwii/downloads/detail?name=MultiWii_quad_variable_pitch.zip&can=2&q= Perhaps there is some idea…"
