"detail process?"

"Did you have resolved this problem? could you tele me your method?my email is:maxweiqiang@sina.com
thanks you very much."

"Thank you much for your help.and ANGLE_MAX?"

"and what does the mean about

ANGLE_MAX?
and  my ANGLE_MAX has been set to 4500.it's right?"

"You have knower the method about apm2.6 airspeed without airspeed sensor?"

"Have you clear about wind speed/dir with mutimotor?"

"Thank you very much.yes,the error is lack of many libraries.Have you any suggestion?"

"ok,I will try vs 2013 desktop"

"Directly measuring wind with copter is simply,but it really won't give an accurate result and ..than do you have any good idea?Does traditionnal wind sensors use pressure sensors?"
