Drone motor trims

Trying to achieve a higher horse power from a Arduino, for what else other then drone motors!  The mid level four logic's would be each a PWM (using analogWrite() to digital pins for speed control).  The 7.4v is direct to the battery plugged to the VCC on the Arduino, skipping the 3.3v or 5v on the Ardunio itself.  - nforystek

the logic inputs are sinking 2 amps when low

Add a 100Ω resistor to your power source which solves the excessive amp problem - rpm range will reduce from 1.91 krpm to 1.41 krpm.

I want the excessive part. I have a few of these motor circuits, my ultimate goal was to get a Arduino with aux 7.4 or 3.7 voltage to power small 3v rated motors and I'm unsuccessful so far. I have 4 PMW's available and 8 logic. I am unsuccessful so far, but I haven't tested much since I got everything in place. It's around 40 grams. I don't really care so much as utility as I do seeing it fly! One configuration I seemed to had had enough going, with cooling 2N2222's by Aluminum tube. But I didn't have flight batteries at that time. :(
