It flies! It flies!
But let's start at the beginning...
After having built our UAVP as described in my last article, today we fixed the last problems and did the first testflights indoors!
Everything went well after we fixed some bad soldering on Taarek's board and after having found out that one of the sensors of my own board was not sitting streight.
We made a small movie showing Taarek's UAVP flying in my living room:
Get the Flash Plugin to see this movie.
Then finally, when it was nearly dark, we went out for the first outdoor testflight! There was barly enough light to make some camara pictures and so we failed to put the first outdoor flight on movie tape... :(
But to give you an insight in what went on, take a look at these outdoor pictures!
My own UAVP stands ready for it's first integral outdoor flight:

And up it went! As you can see it really flies:

And it can gain height quite fast, I was astonished myself:

And here you see Taarek's UAVP standing ready for it's first real outdoor testflight:

And it jumped into the air as well:

Then we needed to change our location since it was too dark for unexperienced pilots like us. We went up to the street, where there's some light from the street lamps.
Taarek successfully completed several flights near the street in front of the next building:

These first testflights were very successfull and showed the considerable potential of these UAVP constructs!
We were astonished about their ability to gain height within a very short time and about their considerable agility in the air. They are so agile that we even feared several times to crash accidentally against trees, buildings and the like, just because we could not assess how fast the UAVPs change direction, height or orientation.
Be sure to hear more about our next flights in my next blog entry!




Did you notice a difference in the different motors you and your brother used?
Hi Landon,
Yes, there's a difference. The Hacker 20-20L have a different (more evil) sound and I think they have a bit more torque than the AXI 2217/20.
On the other side the AXI 2217/20 use a bit less current than the Hacker 20-20L and I think my brother is a bit longer in the air with the same battery than I.
Both have a lot of thrust to offer and both offer more thrust than needed!
The Hacker 20-20L and the AXI 2217/20 are a bit overpowered. The 4 rotors do around 2.5kg thrust and the construct weights 1.2kg. You can imagine the rest... :)
If you just want a camara platform for air photography, then you should go for the AXI 2212/34. They use even less current and are perfect for hoovering.

Great info, thanks a lot!!! I wish I will have such a writing skills.
Hello,
I am interested in your Project.
Could you tel me some details about payload, gps option.
Is this drone for sale?
Best Regards
Klaus Löwenhagen
Hi Klaus,
The drone has a thrust of 2.5kg and weights 1.5kg with a 5000mAh battery on board. I'm able to fly 10-15min with it.
This means I'm able to lift 0.5-0.75kg as payload.
The drone is not for sale. But you can build your own! Check out http://uavp.ch !
