According to GiantCod, it weighs 86g:

Another reason I like it is because it's one of the few beetleweight-size brushless motors that has a 5mm output shaft and doesn't cost a bomb. I have no idea how it will perform yet or how big it is in relation to any other brushless beetles out there but considering every review on that page gives it five stars means it can't be bad.
