Popa Stefan commented on Popa Stefan's blog post Indoor UAV capable of fixed point flight and efficient forward flight
"Hypertaxi was our main source of inspiration when we designed it. However, the AS3X system helps you fly it, but you still need to be an advanced pilot. 
In our case, the controller does 80% of the pilot's job. The video shows our first flight test. "

"Yes. APM 2.0 was used for this project. "

Popa Stefan commented on Popa Stefan's blog post Indoor UAV capable of fixed point flight and efficient forward flight
"We used this design as source of inspiration. However, I think that hypertaxi is pretty difficult to fly at a fixed point. "

Popa Stefan commented on Popa Stefan's blog post Indoor UAV capable of fixed point flight and efficient forward flight
"Indeed. In forward flight it tilts and uses the lift provided by the wing to fly like a plane.
This is more efficient than an helicopter because  it can reach high speeds, while the throttle needs to be reduced significantly thus less power…"

Popa Stefan commented on Popa Stefan's blog post Indoor UAV capable of fixed point flight and efficient forward flight
"Actually, nothing happens. The forward flight is just a type of fly by wire. 
So, by default the position of the aircraft is in hover mode. In order to fly it more like a plane, the controller maintains the position given by the control sticks, when…"

Popa Stefan commented on Popa Stefan's blog post Indoor UAV capable of fixed point flight and efficient forward flight
"It is an Unmanned Aerial Vehicle since it does not have a human on board.
However it is not yet capable of autonomous flight, but controlled with a remote. 
Thank you for the link."

Popa Stefan posted a blog post
The UAV is a combination of a plane and helicopter. Therefore it is capable of hovering and vertical take off/landing, just like a helicopter but it can also tilt forward to achieve horizontal flight the same as an airplane. This is done in order to…

Popa Stefan replied to Andrew Tridgell's discussion ArduPlane 2.50 released
"Hi guys!
Can somebody please help me get rid of the yaw drift without using the GPS or compass? The roll and pitch are not drifting at all, but the yaw usually gets out of control in a few minutes, even when I keep the aircraft on the desk. 
I need…"

Popa Stefan replied to Andrew Tridgell's discussion ArduPlane 2.50 released
"I noticed in the new AP_AHRS_DCM.cpp code that independent drift correction was introduced. Does this mean that yaw drift can be corrected without the use of compass or GPS? 
I am really interested in finding a way of getting rid of the yaw drift…"

Popa Stefan commented on Chris Anderson's blog post Updated ArduCopter and ArduPlane code: APM2 users please upgrade!
"Hello, 
I am looking for the servo_out variable in the newest Arduplane code and I cannot find where it's value is being calculated.
I found in the repository http://code.google.com/searchframe#iTqA9ErfVSM/ArduPilotMega/trunk/... formula, which…"

Popa Stefan replied to madhuran wilson's discussion developing ardupilots for unconventional airframes in ArduPlane User Group
"Hi!
I am very curious to know if you managed to pull this out :).
It looks like a nice project and I am also planning to try the ardupilot with an unconventional airframe and I would like to know if it is possible or not.
Thanks.
Stefan"
