Typhoon H GPS Lost! Fly Away! My story!

Last flight telemetry

Oops.....sorry I left out a step. Just add a .txt to the end of the file name so it will upload here. The PDF files won't help me.

@Chaos@ir

The files you posted have been opened by Excel or another similar program and it places a tag on the file that makes it unusable with the program most of us use to analyze the data.

Make a folder on your computer 'CrashLog' and copy the Remote, RemoteGPS, and Telemetry files from the ST-16 for the crash/flyaway into it. Then zip the folder and post the resulting zip file to this thread.

I use a Ping GPS tracker on my drones just in case.

I use the trackimo GPS tracker

What was your launch altitude, 8939 feet?
Wooooow, I'm surprised it flew at such an altitude?

They will actually take off and fly much higher but flight time drops considerably due to a large decrease in propeller thrust at high density altitude. Best thrust performance occurs in a “sea level” environment. Oxygen density decreases 50% at 18k feet with thrust performance decreasing roughly proportionally. You already know all that from your helicopter history but most likely didn’t.

If the motors could turn proportionally faster at altitude the thrust loss could be offset somewhat but motor speed is limited by the ESC capability along with battery capacity and C rating. To turn motors faster requires more current which drains a battery quickly. This is an area where a constant speed prop would be beneficial but the cost and weight would be exorbitant for the added performance.

Just about all the consumer drones are built to a minimum power requirement standard which leaves very little “headroom” for performance upgrading.

For those adding “widgets” like Lume Cubes, GPS trackers, or even higher capacity, heavier batteries to an H, recognize the addition of only an ounce or two decreases flight time. The H is very sensitive to weight gain where flight time is concerned.

Those telemetry files are too much destroyed. Way too high effort to recover them. Could you please please put the original CSV files into a ZIP file. ZIP files can be attached without any additional effort.
