Decided to convert the MonoProp to test the autonomous unit with ardupilot. As can be seen in the pic we have lots of cables. The reason for this is that I have an Arduino board at the exit of APM to...

Today is windy, perfect for a test. I was getting awesome horizontal performance and smooth transitions, but the vertical flight performance didn't impress me in the first test. So, did some further...

Took this video to see how the active wings work during a flight. Windy day and the gyro compensation is pretty cool.

This is the 10 min flight. Still have some minor issues, with flutter and balance. But overall it was a good flight. Used 90% of the battery, which puts the estimated maximum flight time to 11...

I re-built some parts of the unit due to some build errors. Re-tuned the unit and took it out. A much better flight. There is a little wing flutter when hovering and a little bit of wobble in turns....

There are still lots of tests to be done. If I don't get a decent flight time in my eyes this is failed. In the last flight, the wings were extended further than the previous one, which gave me a...

The first short hover test is with an old 1300mah and the second test is with an older 2200mah battery. This is not bad. A little more powerful battery of the same weight should do it. The unit tends...
