"Hi iyad Have you solved this problem? The TimeMS is the milliseconds since the start of the week - the week number is in another column. I just use a web site to do the conversion to local time."

i have logged my flight data into the mission planner and it shows number of lines for a time period.i'm interested in the IMU data , where it shows 7 columns,3 for the accelerometer , 3 for the gyroscope , and the 1st one is  TimeMS.i want to know how those line numbers and the time are related because i want to know certain values of the the graph at certain time .is it in milliseconds ? microseconds ? or something different ?See More

strongest motors with esc 30A

hi, i have a quadcopter , and am using Turnigy plush 30A ESC's with turnigy 1000kv BLDC's, and i recently installed a heavier frame and the quad can barely hover for 5 minutes.i was thinking about getting stronger motors and keeping the same ESC's that i have.what are the options that i have here ?and i also want to change the battery, am using 2200 mAh 11.1V, what would be a good upgrade for longer flight time ,since bigger motors will consume more energy?See More

Joe Frazier replied to iyad's discussion ESC keeps beeping no matter what i do !
"I believe that a continuous beeping like you have is an indication of an ESC problem. One of mine did the same thing, and I had to replace it to correct the problem."
