I think it would be helpful to those who follow along in the future if we were to list out our hardware for comparison and tuning.  It would give newbs a place to work from in terms of design, expectations and PID tuning.Data to include: type of copter, autopilot type, Motors, Props, ESC's, Battery,  Frame diameter, Transmitter /receiver, Usual home altitude, Accessories onboard (sonar, flow sensor, telemetry, LED's, camera ...) and of course, PID's that work well for this airframe.  Be…See More
