Thanks to the new parts of 0.25 many drones were born.
They think it had something to do with huge loss of Kerbals since the KSC was founded with over 10 trillion Kerbals being killed ever year. so the engineers Made new parts for these new planes where if the Kerbals crashed they would still be alive.
But Jeb being Jeb, he asked his old team that made the KERBAL-FORCES (this pack is out of date) to make him and his friends some new planes so these types of drones came to be.
The Drones are:
HS Drone Bomber: A high speed bomber that carry's three bombs that can dropped all at once or one by one.
HS Drone Bomber MK II: The MK II can fly faster and higher than the normal type and carry's the same payload.
TIP: Take off fast but at a low angle or you will rip of the engines .
HS Drone Fighter: A fast and light fight that is designed to challenge the best of RC pilots.
TIP: Use reaction wheels or you will lost control whenever you try to turn.
These planes are all stock (Needs no mods).
