ROTORFLIGHT - Blackbox PID Tuning the Oxy 5 Meg

The writings, analysis, screenshots surrounding the effort to understand the blackbox trace behaviors and PID tune center around the following model. Having personally PID tuned approximately 53 different RC helicopters (personal, acqaintance, and for compensation) as well as over 60 different drones (business, acqaintance and personal), I found this model was a slight challenge due to the nature of it's very high performance servos. Please make a note of that for your own model and tuning experience.
