I have a goal to fly the arducopter higher than the current tallest structure 829.8 metres and record the flight. I intend on doing this on a calm day but expect winds at high alt. I do not know what speed to expect. Has anyone brought you copter to a high alt of this value and any learnings i can take?

Love the idea, sorry I have no insight. How do you plan on flying? Loiter and full throttle up? Are you using a quad or hex or something else? Have you given any thought to flight time and battery?
Good luck and fly safe.

The plan is a mission with one waypoint and rtl. I will certainly be doing some battery tests and enable low voltage rtl.

I think its not allowed uless ok by the FAA.

I'd work on a parachute for it FIRST.
I'm building my first one now and m already trying o invent a chute for it . bo

COol, keep us posted on the chute

What I would suggest is put it in Loiter and do altitude tests, increasing by 100 meters each time to gauge your batteries. I have a perfect place to try this and might give it a shot. I'm already at 250 meters starting altitude but I'm near an airport so have to keep it safe.

I would love to see your results and actual weight of your quad.

Yep, good idea. The thing to be wary of is that unlike a plane you need a lot more throttle at landing than you do descending. If you're doing a fast descent at the end you need to be sure to have enough juice left to pull out of it.

BTW, is there an altitude record for multicopters? I know with a plane it's easier to get up high but I tend to shy away from taking my copter too high even though I don't have a range issue with my fpv gear.

I dont know if there is a record, i coulnt see much information. We have sent a weather balloon to space before.

There are several Youtube links I recall viewing at 2,800ft which is higher than your goal of 839meters?

At these altitudes you may want to consider flying FPV otherwise you will loose sight of the multicopter above 200meters. You could of course also use a spotter with binoculars but it seems to me that FPV would be the ultimate way to do this? Good luck!

1500 feet:




I had a bright idea once. I felt my quad was descending to slow from a high altitude flight so I let it free fall for a bit. Once I noticed the props stop and start spinning in the opposite direction I quickly realized it was a dumb move. I instantly gave full throttle and 2 of the motors managed to flip the direction and the other 2 didn't.

In the end after the barrelling ride to earth. I noticed I didn't turn on my camera.

Now I found that I can return to earth very fast by pulling all the way to one side with the cyclic and bring the throttle really low. My motors don't stop spinning that way.

You are saying you put the right stick (pitch/roll) all the way to one side and then drop the throttle to almost zero???

I prefer to use alt hold and pull throttle to zero. You can increase that drop rate in the advanced parameters but I find even the default is a very unstable descent. I usually have to bump up the throttle a bit to keep it from rocking around so much. I can't imagine doing a free fall and hoping it recovers before the ground. I use to do some quick descents in stable, to the point that the quad would start to flip but then the props would start going backwards with no way to recover.
