Last night, I upped a formation of Ki67s and heard explosion as I was taking off (auto pilot) no enemies in bound. Checked my external view and 1 drone was missing. So, I ditched and tried again. This time I watched, to my amusement, when the trailing drone quickly backed away, lifted like a jet and got far enough away to explode.
I did it several times to see if anyone else was seeing the same or was it my computer playing tricks on me (plus it looked so darn funny:lol ). Information about base is on my other computer, if you need it, I will make a note and post again.
I am just posting here, in case the good folks at HTC weren't aware of this yet. I must admit, it was more funny than anything else. Zooscrew finally walked over (chute) and inspected my props

Maybe last drone pilot had it in reverse:p
