Re: MultiWii dev1342 issues

same problem for me. Till official 2.1 everything was fine, but on newer versions i am having trouble with arming my copter. Sometimes it arms on the first try, but often i have to reconnect battery multiple times, or try to arm (THR 0, YAW all the way right) 20 or more times until it arm properly.

Servo - wider pulse range

Hi, i have just built my camera gimbal and found that i can't use my tilt servo as direct drive, because it causes lot of jitter in my camera. So i thought if it is possible to make wider servo pulse range from actual 1020 - 2000ms to 500 - 2500 ms , so servo will be able to move full 180 degrees wi...

Hi,
on the table it takes 5 seconds to reduce from 1860 to 1750, 15 seconds from 1860 to 1550 and about 1 minute until it drops from 1860 to 1450.

Re: bug: motor value drifting due to errorGyroI accumulation

I would first be more interested in your battery C rating than in the gui performance. 6 motors would require at least a 40C battery. no, battery is not a problem. I have 2x 2200mAh 25c in parallel, that is 25 x 4,4 Ah = 110A continuous. My motors should pull max. 75A at full throttle. The problem ...

I have slightly different problem, but related to error accumulation... In GUI I see that over time the speed of each motor will differ, but in the air it behave actually pretty stable. My problem is that my Hexa is lacking power under full throttle due to this error. It has no power when fully load...
