This was flying my iFlight Nazgul5, using TBS M8-2 GPS unit which gives average of 11-14 sats in this location (have had up to 17 on occasion)
Top speed was straight out of a vertical dive, with a 20-25mph tail wind (it was very blowy tbh!)
I watched the speed on the OSD rocket up to OMG levels, I saw it climb to >200kph - but only saw the max speed when reviewing the video from the goggles later as I was kinda busy at the time…
One off anomaly? - I’m not sure what’s actually possible - and I wouldn’t want @notveryprettyboy to think I was after his record if this is dodgy data! (It did however juice almost an entire 1500mah battery in 2.01 mins. )
