Can this affect level so badly?

So I bought one of these things (or one exactly like it), because once while learning fpv I backed into a tree and it took me a couple minutes to figure out which direction my quad was. No big deal, but I could see where it could possibly be a real big problem someday.

So any ways I found myself alone in the park again and I decided to give this thing a try. I connected it between ESC #4 and the APM2.0. I went back to my computer after connecting power and to wait for the GPS Fix. When I looked at the HUD, I saw my quad was a whopping 40 or 45 degree's slanted to the left. 

.huh.

So I walked back over to the quad (GPS had 3d fix now) and gently spun up the motors... And truly yes, my quad leaned HARD left as I tested throttle up. 

So I removed this tiny thing (it's about as big as a US dime or 1cm), reconnected power, went back to my computer, and checked the hud and it was fine. (and it flew fine)

.

WTF? 

Can something this tiny really affect level so dramatically? Or did I just happen on some co-incidence and rebooting would have fixed level anyways?

Didn't attach logs, cause I'm not sure they would show anything except that "yeah, it's not level".

v2.9.1, APM2.0, Quad.

  • Alrighty, so my level problem has returned a couple more times. Today, when I went to take off, my copter leaned hard. I went over to it, hit reset, the quad rebooted, and it was fine. I don't get it. 

    After that it flew ~2k mission without a hitch. Is my APM 2.0 going bad or is this a software thingy?

  • Yes I've had problems with the HUD rolling all over from plugging and LED in the wrong output port - where did you plug it in ?

  • WTF is it?
