Wemotec Mini 480 "What Motor"

Well this will be my first EDF and I'm trying to do it right. I have a Wemotec Mini 480 fan unit, I see one set up that is affordable and seems to produce good performance is the HET 2-W motor. It is specs. show a 4580 RPM per volt. I would appreciate any input on what other choices I may have.
I will be installing it in a RT Models Mig 15 AUW should be around 36 to 40 oz.
I will be sticking with 3 cell lipos to try and keep the AUW down. I have a few 3200's and a couple of 3c2p4200's

Regards,
Nut

If you are planning on using the 3s batteries, the 2w or the mega 16/15/2 are both great choices. I really like the 16/15/2 on 3s for a good light setup.

Het 2w and 480 fan

I have tried the HET 2W motor with the 505 fan (same as the 480 fan but without the shroud) in a kamodel sabre and got about 400 watts at 40 or so amps but with a weight penalty of higher capacity 3 cell batteries. The alternative set up was the 3W motor with 4 cell, which used lighter batteries and lower amperage (1500mah) but gave up 100 watts of power. The 3W motor and 4 cells produced close to 300 watts but at a lower amperage of about 30.

Markos at Warbirds-rc has posted HET motor/fan test results at http://www.warbirds-rc.com/ResearchC...sts/index2.htm

I also have the RTModels Mig in my building queue so I am very curious as to the outcome of your choice of motor/fan/battery combination. From my experience with the sabre (my first edf), I found it difficult to keep the AUW down given the added inherent weight of an edf system and the need to provide enough power to sustain flight.

Thanks Guy's

I will start the build this weekend. It sounds like I can use what I have with the 2-W motor. I also have a CC60 ESC that should give me some wiggle room.
Once I get the Fan mounted and the ducting installed I'll do some bench testing with the batteries I have and post the results.

Thanks Again,

Nut

Hi--
Did your Mig fly? How did the 480 fan and the HET motor work for you? Thanks.
