I did a first test with RTL on 2.5.3 today. After GPS fix I took off ans steered the copter away from me in STAB mode. Went to RTL mode and watched the copter reaction. Instead of coming back he…Continue

"Solved it!! It was the prop that caused the problem. Couldn't see a difference with the other props on the copter but by changing with a spare it made it clear."

Hi Guy's. Hope that someone can give me tips on how to solve my strange copter behaviour. I'm running a APM1 in X config. Every time I try to take off, the copter's back left arm (motor 2) stays behind. So I started with the basic stuff, correct motor rotation CW and CCW, correct propeller on each motor, ESC calibration, level procedure, compassmot which is at 10% and finally the vibration which is within limits on all 3 axis. Following on from there I enabled 'motors' in the log, put the…See More

"I'm having the same issue. Can't lift off vertically. After switching from APM to DJI I returned to APM again on version 2.9.1. After upgrade to 3.0 I can't get the copter of the ground anymore. On my quadframe in x configuration the…"

"There are two ways to handle Simple mode. You can set CH7 input to toggle it independent of mode. Or you can set them permanently to each switch position and use CH7 for another function such as saving waypoints. There should be little checkboxes…"

"Jason, What do you mean with 'enabled per switch position'? If I enable 'simple' by checking the box in MP setup, does this means I'm not always flying simple? Jan"

"Simple mode is enabled per switch position. This enables users such as FPV flyers to do more complicated setups. You may have been confused since the Quad was rotated at 45 degrees and when it wobbled off your controls were not translated by simple…"

"I had a look at the log file. It seems the copter rolled heavily to the left after rolling right. Maybe it was a little unstable or windy or your gains aren't tight enough. The copter increased thrust to maintain altitude which caused it to…"

Copter behave like my dog who sees a rabit

After flying my 3rd lipo in a row with no real problems, suddenly the copter takes of very agressive. Was flying in alt hold when it happened. No reactie from the remote when trying to bring the copter back to launch position. Switched to STAB and landed. After this all looked normal again. Except the broken landing gear...Logfile and sketch attached. Anyone had the same problem already and knows how to fix it?See More

"Unfortunatly the Mag fix didn't solve the RTL issue. Did a test last weekend and same issue appears. When switching to RTL, the copter flew further away instead of coming back to launch. I attach the logfile and sketch about what happened.…"
