My top speed.

[slim.slamma]

The only practical way to get a meaningful top speed (other than a completely windless day) is to do two runs, in opposite directions and take the average of the two speeds. I once recorded 84 mph in one direction and just 42 in the opposite direction. An average speed of 63mph.

However, even this result is misleading as it is the product of the peak speed in both directions and will therefore add any wind speed variation during each run to the resulting average speed. Thus, if the wind speed had changed by just 5mph during each run, then the average mph could be up to 10mph lower than the average of the peak speed measured in each direction.

I guess you could do two timed runs in opposite directions over a measured distance but this would be quite difficult to do with any accuracy.

I need a moment to wrap my head around that.

I'd say "interesting" but you might take it the wrong way.

84 in the UK? No way!
Don't tell Mark...

Air density and thermals in the air will play a little role in the speed also. Only real true way to get accurate speed is in an enclosed area that isn’t affected by the elements.

**** I drive up to B-lo every so often, the only Bitcoin ATM in the state.


Might pull up on you one of these days

Hard to believe that is the only place in the state that has it.

The City got hundred's but the State is on funny time.
Go to PA with a Nys state I.D. you get denied

Only 84mph because the prevailing wind was probably helping it along by a good 25mph....

Not the sort of thing to try unless you are in a large, open, unpopulated area. I was at a local UK race track at the time filming for a US TV programme that wanted tracking shots of the cars along the main straight. It didn’t help much as the cars were hitting topping 135mph by the end of the straight! Great fun all the same [emoji3]

See mine (and all countries I flew my drone. Germany and Belgium are not visible).
My actual top speed is 99,7kmh

If they want you to keep up tell them to buy you a helicopter. Lol.

84 in the Air is fine........ there’s no speed cops with radar guns up there.

That's gonna be hard to beat!

His is in km/h so that’s like 62 mph.

That passport is what caught my eye. I can imagine the footage he got.

You know I slide off topic from time to time.

My apologies to the OP

How is speed calculated in the AC, unless speed is gathered from the GPS data I wonder how accurate it is, reminds me of my days with personal watercraft, where speed is gathered by a little wheel that turns with the flow of water and some riders swore they were doing 90mph, because the speedo said so, yet anther the gun they were doing 50-55 LOL. Even those of us with GPS units were having errors introduces just by the nature of porpoising which completely screwed up the reading.Get a radar gun, then get accurate speeds.

Most of my footage is on YT

Nice. I have those CF Xoar props on my bird, and it hit 68.4 mph on my fastest flight with a slight wind.. actually the top speed is one of my favorite things about the Inspire, and the Xoar props sure help out

 

[slim.slamma]

Landing Gear down speed boost hit 78

 

[Chipdji]

Never did try that I will have to try it.

 

[slim.slamma]

87 MPH
