Smallest EDF jet?

I did a few searches and found some micro model pushers, but couldn't find what I was looking for... What is the smallest EDF that anyone has built? There's got to be an edf 40 F-18, or maybe a 30mm EDF F-14. Does anyone know of any sites? Or Pictures?

Smallest EDF I have seen are the small "zagi" style wings with the edf 50's on then. True jet like plane is the F-4 Phantom with the twin EDF-50(?) in it.

Can remember the brands etc... but a couple searches on Ezone will come up with some answers.

Cheers,

Ado

The reason I'm asking is because I have this F-14 guillows kit and I'm thinking about attempting a micro EDF design with it. Possibly with retracts and wing sweep. Controlled by tailerons. I took some measurements, The EDF will have to be about 33mm OD and put out no less than 25g of static thrust.

Maybe my ideas are a little beyond modern technology, but I don't think it will be too long before this is possible. Maybe not a guillows kit, but atleast one that is the same size: Approximately a 1:40 scale model.

GWS makes an EDF30 sized unit that's labeled TBA stats published are:
Code:
Model		Voltage	Current	g	oz	Watts
EDF1220x6	7.2	0.6 	13	.46 	4.32
EDF1220x6	8.4	0.8 	16	0.56	6.72
EDF1220x6 	9.6 	1.0	21	0.74	9.60
I suspect one would have to use some tiny batteries on these and push the motors hard. In any case you would want to keep things ultra light
I don't think you could use rewound CDROM motors to power one of these either (motor is too large in diameter).

Does anyone know when it is going to be sold, or where I could buy one right now? at officeshops.com they sell them, but it says "coming soon TBA"

My F-35 isn't that small but at 24 inches long with a 19.5 inch wingspan and over 200 watts of power it shows that the technology is there. 50mm fan

That's a really nice one! Looks like the Air Force version. Your own build or a kit?

Wow. Hey, on my design it is a single swept-back wing with an airfoil (double thick 1/8 inch foam sanded), but I can't figure out a good air scoop design. Any hints?

Meowmix,
I chickened out with the flat plate wing and cut wings with an airfoil. By "scoop" do you mean intake for the fan?

That's pretty small, but do you think that a smaller version is possible? Maybe a 75% version with an 18" wing.
