Here are the new Extreme CNCAlloy 80mm fan housings designed to take the HET 700 series motors. The housing is an all new design with new stators and a 39mm motor tube. The housing diameter matches the OD of the Eflite housing. Brackets are available and silicon on to the sides of the housing, very easy to install, drop the fan into the ducting, tape in place, the line up and mark position of the brackets, silicon them on and let the whole lot sit in the fuse overnight to set, brackets end up in the perfect position to bolt down.

The new fansare being set up with either a custom cut down Wemotec Midifan rotor set much like the TJ80, or with the new CS12 blade rotor cut down to suit.

Performance and efficiency of the Extreme 80mm Wemo fan is on par with other 80mm fans using the Midifan rotor.
My8s setup pulls just under 100A at 2790w for 3.7kg thrust tested in the airframe. Spyda0 on rcgroups has this setup in his Habu, details are on the Habu thread.
I alsohave two 6s setupsthat run at around 1750w and 2000+w depending on motor chosen.

With the 12 blade rotor I have tested a 6s version so far, 2070 watts at 101 amps, thrust testing will be done this week, it should be around 2.8kg ++

It looks awesome, Mark!

Thanks for making these high quality variants for EDF power systems.

Thanks Greg, the performance of the Wemo version is very good on both the 6s and 8s setups, the 8s looks very quick, I am waiting on a customer to do some more video of his with some level fast passes that can be dopplered.
Here are some vids of the setups:
