I would look for a listing of the item where the seller may have given a specification. Usually any item from China is listed by multiple sellers. Do you really want a guess?
Can you offer any details of the item you bought or better an ebay link?

At what voltage 3s 4s 5s etc?
I think that is 36mm diameter by 50mm long. The KV is revolutions per volt. Are you sure it's not 390KV?


Even 2s 7.4 volts would be 28.860 rpm and much more on a fresh charge
