hi all, I am a newbie
Here is my planning Quad turn steps from some videos(Tau Labs Getting Started-Episode 2 - Advanced Calibration) and WIKI pages, please help to check.
(Now I use GCS's default PID setting, quad can fly, but not perfect)
1) use the temperature cal, temperature from 25 to 45 slowly(can use the heat air blower),while the quad just sit still;
2) use the six point cal,and level cal;
3) fly the quad(in rate or attitude mode,or ether will be OK?), by slowly trimming the remoter's "pitch" and "roll" to let the quad fly stable;
4) use the GCS' Airframe Trimming- Set level angle, and move the remoter's trims to neutral ;
5) use the GCS' Autotune function to get the PID
about the Autotune's step from the GCS's warning
Take off, change flight mode to autotune, and focus on keeping the UAV in the air while it's shaking.
In the first few seconds, nothing will happen...
then the UAV will abrupty increase power and start rolling right and left for around 30 seconds...
then the UAV will start pitching forward and backwards for about 30 seconds...
then finally the UAV will abrupty reduce power and oscillations will stop. The flight phase is completed.
does this mean when in the Autotune step, I only need to use the remoter's pitch and roll control the quad not crash something,and the regardless of the throttle. and finally the quad will lose throttle and land , then I can disarm quad, see whether the PID is reasonable or not, if OK, save the PID,change the autotune mode, disable the autotun function,save that's all.
