EagleTree E-Logger RPM sensor accuracy

[tom255]

OK I made some test with no load run to figure out is my RPM sensor accurate or do I realy have 9XL motor
Specs shows:
KB45-10L ~1800KV
Feigao 9XL ~1853KV
I made few runs and here is results:
KB45-10L

Feigao 9XL????


So measured KV is on KB45-10L 1780KV which is pretty close to spec 1800KV
On feigao KV is 2380 which is by specs actualy 7XL
This means that all the time I run 7XL and thinking why my system so hot and fast DAMN!

BTW KB45-10L goes hot pretty fast on full trottle about 20sec it hit about 45*C
