First of all, what motor do you want to use and what airframe do you want to use it in?

1/1 is totaly out of the realm of possiblilties for this fan.

eric i am in the process of sizing up dre's f-22 plans to fit the edf-65, as for motor it is the stock motor until i can get some idea of what motors will work in the fan. i appear to be heading for about 7 to 10 oz area in weight. in my blog you can see some of the work i have done to upsize this plan from dre's edf-40 plans. i am a nubie but love to experiment and build things so i hope to get at least a flyer maybe not fast but stays in the sky flyer out of this.
thanks for your help

Chuck,
We have played around with the GWS64 a bit with both CDrom type motors and with Hyperon 3600Kv inrunners. I think the numbers for the Hyperon was around 17amps for about 15 ounces of thrust on a 3 cell 2100 bat. This was in a airliner type nacelle so you will loose some if it goes into fighter like ducting.

You may want to look at a depron flat plate design. I think I've seen a Panther that was done here about a year ago for the edf64 and it looked pritty good, might try a search.

good luck -- Stacker

Hi Chuck,

Go ahead and plunge into the fun, I knew if there was more informaion given there would be someone to help. I fly Wemotecs and the GWS 55 and GWS 40 in different airframes, its all fun.

Chuck,
Here is a link for a Panther that was done by Esprit440 for edf40 and I believe he also did one for a edf75. This could be scaled for a 64 unit and with a good brushless you might get 1 to 1 using a 20c small bat. pack (1200 3 cell)

I think plans are available on the link.
