What is that, a geared motor? The kit comes with a brushed direct drive 550 Goldfire motor, and a 7x6 prop. So do I want geared or DD for this? I'm thinking a Hacker B40 would be the closest thing to a brushed 550, if it were DD then I have no idea what prop or battery. I was hoping I'd be able to use a Thunder Power 2100 11.1 battery for this, it says 15C continuous, 24 burst. Do you know how big of a 3C lipo the guy was using?
