Personally I think the brushed motors are good enough for me. They do wear out after 8 or so hours of flight time tho. I'm on my second set, got the 19,000kv ones this time. 9$ for for 4 of them. It has a lot of punch. If you were going to go brushless you would have to buy a different FC and frame, so if you're wanting brushless just buy a brushless whoop to start with. Another option is the BetaFPV whoops, I've heard they are very good and they're fairly reasonable on price too.
