G+_Eddie Hughes Posted May 11, 2015 Share Posted May 11, 2015 Anyone know why my 450 class yaws so much? It is constantly turning clockwise and is hard to control. I have no yaw control on my transmitter. I am using the APM 2.6 flight controller but everything else except the landing skids are stock from the know how list. I have recalibrated my accelerometer, compass, and esc's a bunch of times as well as auto-trimmed and auto-tuned but nothing seems to work. I tried different flight modes, (loiter, althold, acro, sport, drift, etc...) but nothing allows me to regain my yaw control on my transmitter. In the video I had RTL engaged and this was the result. Any help is appreciated! Thank you! Link to comment Share on other sites More sharing options...
G+_Fr. Robert Ballecer, SJ Posted May 11, 2015 Share Posted May 11, 2015 Did you set your sub trims 2 zero out all the controls? Link to comment Share on other sites More sharing options...
G+_Ben Reese Posted May 11, 2015 Share Posted May 11, 2015 Trim is the first thing I thought of too... Would one motor going the wrong way cause something like this or would it be spinning faster? Link to comment Share on other sites More sharing options...
G+_Eddie Hughes Posted May 11, 2015 Author Share Posted May 11, 2015 Yeah, I created a 2nd profile on my transmitter and zeroed the trim. Even when I adjust the trim I am not getting any response with yaw... Link to comment Share on other sites More sharing options...

G+_Steve C Posted May 11, 2015 Share Posted May 11, 2015 Going through all the calibration steps in the ground control program should turn up the problem if it's electrical since it checks all R/C function and compass and GPS too but if that doesn't identify the problem then about all that is left is a physical problem such as a bad motor. Maybe borrow Fr. R's motor thrust tester? Link to comment Share on other sites More sharing options...
G+_Eddie Hughes Posted May 11, 2015 Author Share Posted May 11, 2015 My last assumption are with the esc's but when I switch back to the KK board it flies great. I did notice after this crash only two of the motors, (1 and 3) were warm...the other two weren't warm at all... Link to comment Share on other sites More sharing options...
G+_Eddie Foy Posted May 11, 2015 Share Posted May 11, 2015 Looking at it yaw, it seems to rotate around a single motor. Link to comment Share on other sites More sharing options...
