How do you mount the motor in this thing without cutting the **** outa it? or do you need to cut it for wires?

From the picture, it seems that the deflectors are before the fan. Is this the case?
They should be after to minimize the rotation of the airflow?

stumax makes a pusher and it works and sounds great, i know this one is smaller but maybe it'll sound cool too

can't you justreverse the pusher to a puller by reversing 2 wires on the motor?

What size motor fits in the housing? What KV/cell count is recommended?

Have a look at:
Turnigy 2836 3200kv
HK2836 3500kv
Typhoon 450H 2218H 3450kv
I've had great success (1kW peak) with the Turnigy 2836 3700kv in a 6904 fan on 4S.

This is a WM400 knock-off minus the exit cone. Note that it is a pusher - the motor is in front of the rotor. It will pull more amps and handle a lot more power than the 6904 Het fan. to get the most of it you'll need lower Kv and higher cell count, if it is like the WM say 5 or 6S and 1.5 KW+

28mm motor will fit. Motor of about 3000-3600kv on 4 cells or 2200-2800 on 5 cells. on 4cells it wil draw about 60-70 amps and 5 cell set-up should draw about 48-58 amps but will be stronger than 4 cell set-up.

I have tested with a 2215 3500kva motor and pulled 700Wp on 4S - that's around 25% more than a Wemo with that same motor. As supplied it required a bit of dremel work to fit that motor because the 4 mount holes are 45 degrees off for an out runner and the wires conflict with the stator blades. also the motor will need a long shaft - the 2215 has a 16mm 3.17mm shaft and I had to drill the centre hole out to 10mm and grind the housing in order to bring the collet 'home'. There is zero thru-flow air cooling? Again had to drill 4 cooling holes to let air pass-thru the housing? Not sure what the cloners were thinking - On the other hand the fan rotor is well made and static balance was 100% right off the bat. Dynamic balance was still required. Two collets supplied with the motor 3.00mm and 3.17mm 1/8th. I am going to run mine a fair bit on the test bench before commiting it to an airframe.

I will try this fan with a hoffman magnetics The Beast both 4 and 5S setups.. I just hope my 80amp turnigy ESC can handle it.. I will let you know of the results.. e-mail me at paul_constantino*hotmail**** if you are interested but I will have to wait for the slow processing of HK to move and send my order
