Changesun / RCBLOG 64mm 12 blade EDF with QX-Motor QF2827-2300kv motor

I just balanced a pair of Changesun/ RCBLOG 60mm 12 blade EDF's with QX-motor QF2827-2300kv motors. They came with the stock SU-27 model discussed here
http://www.rcgroups.com/forums/showthread.php?t=2287508

Very happy with the results running 6S.
Here are the test results running a Gens Ace 6S 45C 5000mah battery
1700watts 77amps peak (total watts both fans)
settling to
1550watts 73amps

The motors stayed nice and cool never exceeding 110F

I listed "Changesun" but on the shroud it is marked RCBLOG. I'm assuming Changesunmakes it as the fan is identical to Changesuns 70mm 12 blade fan only smaller.


The ESC's were not in the airflow and reached 135F.
The rather thin motor wires felt fairly warm but I do think they will be fine on 6S (as a twin setup). Specs and temps would be a little higher if the fan was run as a single on 6S.

I'm impressed with the smoothness of these motors especially considering they are outrunners. QX-motor QF2827-2300kv

Sounds good!

Looking forward to a new video by Feda showing the improved sound in that Su-27....
