I did some calc’s. You need about (10-12) 775’s to lift about a 50lb bot. CIM’s and mini-CIMs are too heavy. You’d probably have 3-4 min of flight time at best with the 15Ah battery.
It’s challenging. But if I weren’t only on my 3rd year as being a mentor and having a majority of the team new, I would totally be chasing this down. First FIRST team to fly. That is one for the record books. People would be talking about it for decades.
You could build a tethered flying “minibot” I would think, probably could use 775Pros or BAG motors to power it. Granted, not sure what that gains you given bumper and extension rules, but certainly seems more feasible than other years.
Does make you wonder what it would take, given available motors, required component weight, and size restrictions, to make an FRC robot fly. I have this image in my head of a team building some insane custom quad-turbine monstrosity powered by 16 775Pros… ::rtm::
148 built a 9-sided robot quite some years back. They opted not to put a round bumper on it, for some reason. As I recall, it was very speedy and did quite well in competition, ending up on a couple of winning alliances.
