Frugal Healer 642 S01
This bot is very small and uses very little CPU, however, it has 6 nano so it's a decent healer.
The nanos are mostly facing down, so while this uses rotor blades, it's meant to be piloted like a hover. You hover above people like a hover and you'll have all 6 nanos healing/damaging someone easly.
Although it's long, it's sleek, so it's hard to get hit if you're facing someone. Since it's long, it can reach other players so you can easly have 3 nanos each healing 2 players. Or sometimes one of the center sides will aid a 3rd bot.
The design is imported from when game had seats, so the center is pretty solid now that I filled it with cubes. So it's hard to get one-shot as in worst case scenario you would end up with 50% of your bot left.
Given the rotors are on each side, it'll also survive with some movement capacity in case you're heavly shot, so you can escape tough areas and wait until you're back to 100%.
Also, given it's small, it's excellent when you're with other healers, so you'll be healed faster and will be back to 100% healing everyone with your 6 nanos again.
And, if that isn't clear enough, being small means being fragile. This is a full-support nano, you can't get into fights. The idea is staying behind cover while you heal the mega or other healers.
