Finally, took severe tweaking all over, but seems to be flying ok, now.

Interesting, and very good.
Can you give more details? Which paramotor? Size, motor type/power, how servos connected to raisers, total weight, endurance etc.And which autopilot do you use? What sensors do you have on board? How didyou tune your autopilot?

@Roberto,
The canopy I bought from uflyrc.com, would definitely do it again, is very maneuverable. Very useful for blowing off steam, flying for fun, after another frustrating failed flight test. Practical applications would require a much higher aspect ratio. the motor is a c28-L, I think, has a 30A esc (were the ones I had by the time I was assembling it). Endurance is very low, a few minutes, speed is very low. The system is VERY MUCH affected by wind, is always crabbing, or worse. Flying backwards is not, at all, unusual. I have a logomatic on board, identified the system (as well as I could - I did that many, many times in my life, this was, by far, the more challenging case), and designed a first cut for the loop. The altitude loop was easy, the latero-directional was pretty much a nightmare, the parasail has many annoying, tricky, quirks, that reduced my scientific approach to a long and tedious trial-and-error campaign. I was very much disappointed by that. If you plan to do anything close to this, shoot for very high margins, and brace yourself for the very strong effect of wind in the control loop (you will need all the margins you can get). I have one servo moving a bar with the risers attached, my next step is to add another servo and bar, and control the risers independently, I have to install another computer, though. I plan to add a ultrasound range meter to develop a automatic take-off and landing, just after the split risers. good luck.

deve ter sido muito complicado colocar e estabilizar o paramotor no ar com um servo motor só.
e a vela era de qual tamanho ?

Ernani,  I have some questions I would like to ask you about the paramotor. I'm stuck with a project i am working on and I would like discuss this with you.

@JD: not with a HK canopy, I hope.

Hi Ernani, Just sent you a personal message.

Hello Ernani, can you help me with a similar project, with the code and sensors?
