Happy to report the Firmware updates went in smooth, and she flies straigh and true
Got my 35m/s!  Whoop Whoop, thats 126km/h boys and girls

Still some GPS loss here and there, nothing that gave me jitters
Nice solid video, nice range

Pfffff thats 78mph! Wow

I have read conflicting figures and never believed any tbh.

Is that the top speed?

I read a phantom will go 20-25mph too and wasn't sure.

How did you track the speed? with the app or did you have a separate gps/gsm tracker attached?

The flight record is kept on the iPad under User Center

Fantistic,  thanks for the report.  I just upgraded tonight and relief to know its all good.

My phantom regularly flies at 27mph but one time I saw it hit 38mph

We should open a new thread called "imping the I1 for speed"

Great news and relieving. They will get it down pat, just a little time and reports from the community. Now on the speed did you change the motors to Jet Turbines. At that speed no worry about someone with a Shotgun taking you out of the air

I think I am going to have to pay more attention!

I'm convinced I can get 90 mp/h

Definitely going to attempt 40m/s (90Mph) this weekend

Pretty sure the airframe is good for it

What are you guys clocking?

How do I know if I updated the firmware successfully. Status indicator never moved, it stayed on 0% for 20 minutes. I was getting the D DD sound so I restarted. However after looking at the generated text file on the SD card the update status read "CANCELED".  The RC updated successfully, but not so sure of the aircraft. Please help!

Look at your "about" page and check the firmware version
There is already some pics posted of what the versions should be post updating

Got mine to upgrade today. Took a little time playing around with it and switched out two different SD cards but all is well. Flew it outside with no issues. Took it inside (6000 sqft. empty warehouse) and flew it for a few minutes. Did fine for about 3 minutes then all of sudden it lunged forward quickly on its own. I quickly pulled it back and landed it before a crash could happen. Only thing I did not do was run an IMU check before flight. I will do this tomorrow and see if this helps. Other than that one mishap it flew perfectly.

From what I've been reading .... There are three responses. Failed, which speaks for itself! Successful, which means an update was required and done, and cancelled, meaning the update was already there and not required. I am only repeating what others have written do NOT take my word for it.

What have you changed the gains to in order to get those kind of speeds.  Don't think I'd ever attempt but I'm curious as to how you are obtaining those speeds.

Just a strong downwind leg!
