If you put scanner into rocket miner which is not supplied with mining pipes, it will immediately start flying around up and down until battery charge reaches zero.

IC2 1.19.2-2.0.8.1

That is technically not a bug...

The scanner is the starting item of the drill. Put that in last and you should be fine.
Or if you want to be extra sure insert power last.

Well yes, but it would be nice to have a feature of not allowing rocket miner to start without pipes. Or at least mention this thing in ingame wiki to prevent unpleasant situations. Imagine if you put fully charged glowtronic crystal, forget about pipes, put scanner and then wait an eternity until the crystal discharges and the miner flies to refueling position.

Yeah that is the reason why i didn't close the issue.
