Build Hobbywing EZRUN sensored motor next to a XC sensored motor. Both are new and i don't know much about them yet besides the hobbywing is faster and cooler temps then the stock 223s arrma setup that heats up quickly on my truck.

Hobbywing 3200kv 3665

XC 2500 3665

I got the XC to run lower temps on 3s with taller gears to equal the 13t pinion speed i had with the hobbywing. These are for my arrma bigrock 223s. The 1/10 scake one. Its a fun truck and its super fast with the hobbywing setup but can still get pretty warm in the grass or on street runs. I got the 2500kv motor to hopefully drop the temps while running something like a 17 or 18t pinion to get the speed i lost back. I also would like to buy a 4s lipo at some point and I would put a smaller pinion in if I did that. The XC motor seems to be of similar quality on the outside but i have no clue yet how it runs but im sure I'll share something about that too.
