That's a beautiful shot! How long was the exposure? But I was so hoping you had reached 10,500 feet "the hard way" after launching at sea level. :-)

Fully agree with Mark, super shot of the copter!

 

And is this the max altitude anyone has flown at using one of these kits?

 

And with enough battery power would we be able to get this high from sea level? Thats getting on for 2 miles up...... :)

Guys, Kenneth's not saying he flew that high from start.

He started that high. (notice the bldg behind him)

Gee people, I don't think they make Lipos that big!

well if you really want to find out. put a gopro on it and launch at sea level and just before the battery runs out deploy a chute to bring it back down.

what is the max acceleration rate vertically and how long can it be held constant.

yea i know hahahaha.

Cool location, what a great photo.  Nice stars.  Where is that observatory?

That's what's in the background ;)

Hi All,

Thanks for the comments. The Observatory is located in Arizona atop Mt. Graham. This is the Vatican Advanced Technology Telescope my day job. The location at which I was standing is 10,500ft. I have measured the Hex verticle climb to be around a 1000ft/min at 3/4 throttle(crude measurment). So, doing the math it is possible to climb to 10,000ft from sea level in 10 min. This however, does cut into the battery reserves for returning to earth let alone the fact the Hex is out of site. The exposure time was 14 seconds and the photo credit goes to Dave Harvey my co-worker. This is what we do in our spare time between observations.

 

Ken.

Fantastic!

So to clarify, you started at 10,500 ft and climbed to an elevation of 10,550 ft, meaning that you were only 50 feet off the ground (50 ft AGL). I think we should be very careful with standards and reporting altitude on here. My first time through it sounded like you were hanging out with aircraft at 10,000+ ft above the ground, in controlled air space, at night. That is totally different than 50 feet off the ground.

I should also say that that's an awesome shot and good research. Thank you for sharing!
