Want to replace 3.7v, 46000rpm motor in my fxd 68688

My rc heli has this motor ot-rk-370ph-5133/49. I found this link https://www.sinoning.com/product/small-mini-370-dc-motor-3v-12v-46000rpm-high-speed-strong-large-torque-ot-rk-370ph-5133-electric-motor-diy-car-model/

which mentions the spec. Not sure I'll find this motor in India so looking for a similar specd replacement.

These days motors have a KV unit which I'm not sure how to compare to RPM.

my surprise, the guy in this video:https://youtu.be/DtWR3l5scH0 is using A2212 1400KV motor which would provide only 1400x3.7=5180rpm which I'm not sure would be enough to lift up almost 500g heli?
