Expensive when you're used to hobbyking

still not bad for a 120mm fan

Interesting spec.

Description:-
-Outside Diameter: 128.2mm
-Rotor Diameter: 119.2mm blade
-Meterial: carbon fiber reinforced Nylon rotor
-Suitable motor 530KV-650KV for 12S
-Shaft adaptor to motor: 8mm
-Max RPM 28000RPM

I did a few quick calc's for 12S + 650Kv motor

12 x 4 (volts under load) = 48V
Motor Off load rpm, 48 x 650 = 31,200 rpm
Loaded rpm 70% (keeps it near peak efficiency) 31,000 x .7 = 21,840 rpm

21,840 rpm seems pretty slow for a ducted fan, so not for Fast Jets
Static Thrust should be good plenty of acceleration for Take off
Efficiency should also be better than the higher rpm (less blades) models.

All theory of course , I could be totally wrong

Here is one with an 800Kv motor on 12S
probably exceeds the Max rpm spec.

I like the way they all hide before starting it

Mine runs at 34,000 rpm, that 8.8kw fan looks good, mine is "only" 5kw

Hi paul the flyfly hawk out performs my old hawk.
here is the cs 90mm running 10s 12s with a new hub made by usa,rc jets
i think i will use the 10s setup with 1000kv het.
