Hi,
I got a wobbling crash from 1 meter height for my X4 copter yesterday. The uncontrolable wobbling happened 2 seconding after taking off and was caused by an unexpected changing from X4 to +4 in my APM 2.6.
The problem turned out to be a Mission Planner issue. I am running Mission Planner (1.2.99 build 1.1.5197.12871) on Windows 7 64 bit connecting my APM via 3DR radio telemetry.
The issue can be repeated in following way
---Connecting APM 2.6 of X4 frame type by telemetry.
---Clicking Wizard and close it immediately without doing anything at first step.
---Checking your frame type, it is now +4.
MP Wizard doesn't remind me anything about this change.
This may probably a bug in MP, please fix it.
Regards.
Yi

Thanks!!!!! This post helped me big time!!!
You are not supposed to do any configs in the air !
Hi, Gustav,
Thanks for reply. I did't config in air. I adjusted some paramaters in evening before the crash and wrongly clicked the Wizard then closed it without doing anything. Unfortunately, Wizard changed by frame type to +4 without any reminding. This caused the crash in coming next day.
Ok,
Well, Mission Planner has to default to something when the wizard starts.
I always do a hand test after changing/updating code.
But I see your point, a warning window maybe?
Yes, A warning window may be quite helpful. Or keeping everything unsaved before one clicks finish in Wizrds, this is the default Windows program behavior I got used to.
I didn't do any cautious test befoce taking off because I thought I just clicked Wizrd and nothing would have been changed. I should have been more careful.
Thanks again.
