😁 I don't know that I'm knowledgeable, but I try to help based on my experience 😉 -i forgot to mention that the stock pinion has the smaller 3."something" mm hole, where as that 3660 3800kv motor has a 5mm shaft, so you will need a new pinion - the pitch is mod1/m1 I just got this set https://www.amazon.com/gp/aw/d/B09ZY4PDBZ/

Do you have an esc for this yet? If not, and you can solder, this is the best 2s-3s bang for your buck esc https://www.amazon.com/HOBBYWING-QUICRUN-10BL120-SENSORED-Touring/dp/B0765Q2SVS/

I'm not a 3s person, but the 3 hobbywing esc I have (4s+) are noticably better/less cogging than my generic ESCs, so if I needed a 3s, it's my no-brainer choice
