you like to change your motorset or looking for a replacement close to the other three to mix them?

i would suggest the happymodel ex0802 19000kv for a new set or here would be nice motors https://www.tinywhoop.com/collections/motors

if you like to replace just one with another, betafpv would have another 0802 motor but they sell them as 4piece kit.

i would directly stick to another motorset :-)

Looks I have to replace all of them, and what you gave me is perfect . How do I know they fit into my betafpv 65x whooper: shaft diameter of 1.0mm and motor mount holes of M1.3 on dia 6.6mm I believe ?

Just FYI, I've successfully run quite dissimilar motors. It works, probably not optimal, but it works.

The quad was a toothpick with three 1202.5 6000Kv motors, and one 1103 7000Kv.

I'd go for the 14k or at most 16k kv version if you still plan to use 2S, the original 17500 was already too high.

Sounds good, make sense, appreciate !

there are standart sizes, pretty all in this size should match...

on 2s 12000kv is still fast
