"i had the same thing, and performed an accell calibration, and it fixed it.
if it happens often, apparently, re-arming with the plane still fixes it for some, but this is the long term solution.
hope my experience helps others. "
"I only know vaguely of the pixhawk option, and of the open-aero firmware for the KK2 board. I'd appreciate a link to more info on the code you are referring to, as i'll need something soon. I'm designing the…"
"That depends on the airfoil somewhat, as different airfoils will fly most efficiently at slightly different angles of attack. 3 degrees sounds like a good starting point, and with such a small model, it'll surely work fine. I'm…"
"another factor to some angle of the motors is to achieve hover with the wing at a slight positive angle. that way, as was mentioned before,the rotors are relatively neutral to the airflow in forward flight, the lift motors will also aid speed during…"
"Please let me know when you get some of those high energy density batteries in. i would like to do a a review on them. i have an ideal platform for their use. i have already flown almost 3 hrs with regular lipos. and while transmitting 2 video…"
"You might want to take aloof at my gemini v-2 design. it's specifically for agriculture mapping and serious fpv
WINGSPAN: 3200MM 126 INCHES
WING ASPECT RATIO: 10.77 / 1
AIRFOIL: HIGH LIFT / NON CRITICAL TYPE MAX…"
"Opinions may differ, but servos and other flight related things, are considered part of the u.a.v., and usually not part of the payload. payload is sensors and other equipment that are extra. if it'a gas tav of any size or…"
my Gemini design would fit the bill. i sell plans for the prototype for 15 us dls via paypal. reply of send me an e-mail a email@example.com if you would like plans. 3.5 meter span, 3hr flight…"
