Hi guys,
Need advice here. I wonder why at Tower app, before fly, the battery reading is 13.9. But right after take off, the battery reading drop to 13.0. After landed and props stop, the reading goes up again.
Why is this? I can't be sure my battery left while flying in this case.
I'm using 3DR power module. Please advice, thanks in advance.
Regards,
Leslie
