Note 1: OSD speed is in kmh. A list of the speeds recorded, direction, and time in the video:

212 kmh (131.7mph) West to East 0:31
230 kmh (142.9mph) East to West 0:47
240 kmh (149.1mph) West to East 1:06
248 kmh (154.1mph) East to West 1:21
241 kmh (149.8mph) West to East 1:34
HOWEVER – GOING FOR AS MUCH AS I CAN GET: Blackbox/gps log says 69.06 m/s which is **154.5 MPH**
Blackbox Log File:
GPS Log File:

To compensate for wind (which was calm), I took the highest reading from each direction and averaged them to get 152mph. However, the scoreboard goes by highest ground speed…

Note 2: Flight took place around 8pm on May 26, 2017 and winds were 5mph max:

Note 3: Very poor OSD reception/quality. The Eachine DVR records a black screen if there is any interference.

Note 4: After much research, I have found out that GPS is the most accurate way to determine speed. A summary of my findings:

Note 5: Flight ended in a small crash – I thought I had turned on angle mode, removed my googles, pulled back on the stick to land it and realized too late I was still in acro.
