Hi everyone,

I recently experienced a crash with a 3Drobotics X8 RTF, APM 2.6 firmware 3.1.5. The drone was in the middle of an auto mission (about 10 WPs, short distance) and has started to wobble dangerously just after a gust of about 3 beaufort until it fall on the ground. No consequent damage, fortunately. I checked the dataflash logs and it appears the frame configuration was set to "Plus" instead of "X". So I have two questions;

-1) How may it possible that the frame configuration has changed from "X" to "Plus". Does the firmware update may cause such an issues? Of course, I select the configuration "X" in the mission planner interface when I perform the firmware update.

-2) How is it possible that the UAS flyes correctly (and autonomously) for half the mission if the frame configuration is incorrect?

In would appreciate any help! In advance, thanks.

    Hi Jo,

    just came across your post. That is very strange! The only thing I could image is that you (accidentally) hit the wizard in MP or something. Not sure if it will fly with a wrong configuration. You definitely should see it if you fly in stabilize mode.

    Could you solve the issue?
