i have noticed the lack of research in the past 2 years (2014-2016) on system identification on quadcopters (multicopters in general). Back in 2013, i built my 1st APM based Quadcopter, and took advantage of the power that the open source provides.…

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…

what should i do ? is this hard to fix? should i change the frame?"
"yes.. Thank you ! motors 3 and 4 have higher values than motors 1 and 2 in the graph. 1 and 2 are almost exactly like each other, and 4 is a bit higher than 3.
but how can i know which arm is twisted ? which way the twist is ?"
hey everyone, i have my Quadcopter with APM2.6 , and Turnigy 1000kv motors,and been having a stability problem where the Quad hovered but kept trying to roll to the right with some clockwise-yaw no matter what i do.i re-calibrated the Accelerometre…
"ok i have uploaded AC v 3.1.5 to my APM and i accessed the terminal and disabled all logs except for IMU and MOTORS.
i went to standard parameters in config/tuning window , and the log bitmask drop-down option is empty. i clicked on Write parameters…"
"sorry , i meant an older version of the firmware not mission planner.
anything before AC 3.2. would work with Terminal ?
where do i find it and how to upload it to my APM2.6"
"Thank you for the reply Bill, but i dont know how to make use of the links you posted.
i know i need to enable #define MASK_LOG_IMU and #define MASK_LOG_RCOUT from the rest , but no idea how to do it manually here.
Would it help if i can just get…"
