This barely edged out the DRL Racer X by 0.50 mph using only half the power of the DRL build. I would like to claim the world’s fastest drone / world’s fastest quadcopter (speed was calculated in the same was as Guinness), but I opted not to bring Guinness out yet due to continuing development.

***NOTE: From 0:39 to 1:51 I had GPS lock up/loss. I loitered around a bit, gave up and was about to land when I noticed the GPS came back.***

Average speed was taken as an average over a 100 meter distance in opposite directions (runs shown in the video). This is the same method used by Guinness. The nice thing is that it doesn’t need a nuclear reactor to hit 160+ mph and no worries about anything burning up. The only issue I ever experienced was pilot error (ran the lipo waayyyy below safe voltage).
