You will spend $15 - 20 or so per motor on any reliable one. You need a 2218 1100kv or close, don’t go more than 1100kv but you could go up or down one motor size. The Emax 2218 is $20 each, that’s the only other commonly available one that size. The cheap gold coloured 2212/1100kv motors you see on eBay are really horrible IMO, buying those is a waste of money, despite them being cheap.
The
Racerstar 2212 is about the cheapest vaguely OK one, it’s not much better than the gold no brand ones. That’s going to provide less thrust than the bigger one, you could go for a
2822 1100kv, which is bigger and heavier but more powerful, so would give you slightly better payload carrying. The
Emax 2218 1100kv is what used to be in the non radial power pack.
You don’t need the motors until right at the end of the build, if you have the rest you can build it all and add them at the end, just be sure you have adequate ESC’s for what you want.
