So in the last post we concluded that the wing extenders weren't doing what they were supposed to be doing. So, what are they good for? Why is the wing extender still in use?
Send the TA Sequoia (halfway) to space! Why not. A year or two ago I met a brilliant guy by the name of Kemal Ficici. He talked about how he really wanted to send a High Altitude Balloon up, similar to what David Windestal had done . I wanted to take part in it as well and offered to design the aircraft that would return the payload and.. well it kind of died there until about a week ago. The college I currently attend has an annual STEM fair and I learned about it a week or so back as well, so you can tell where this is going. What we initially wanted to do with the aircraft was that we would equip it with directional antennas and low frequency radios so we could essentially have strong radio connection even at 10km up, but that led to some problems. What if it suddenly got cloudy? What about the cost of the radio equipment? What about FPV and live video? Then we thought, why not just cut the pilot out of the equation? For my Computer Science final project I had lazily fin...
Well I got it to hover thanks to a certain individual that goes by the name of "Ran D. St Clair." On the rcgroups VTOL forums. Picture for now, once I get the PID values working I'll upload a video.
So I've been having a blast designing my VTOL flying wing. The guys over at rcgroups have the best advice I could find, and the software made by happysundays over at the vtols form (openAeroVTOL) is great. VTOL flying wing in hover mode. So here's what I have SO FAR. I took off the wings for the hover test because I wanted to progress one addition at a time. If hovermode had a sudden error, I might have ended up damaging the wings. I'm writing this at night, so I am getting ready to shut the lights off and finally get some rest, but here are some observations I took in from this nights hover tests. Takeoffs on uneven cement ground resulted in pitch oscillation, while takeoffs on even grass resulted in a smooth takeoff that I had to stop, and land immediately afterwards because it was banking. I did not make an attempt at trying to balance it. The pitch oscillation might have been caused by a really highly pitch P vaullue, ev...
