Poll
Micro ME-262 EDF

In looking for the next project, the ME-262 seems like it would be a good candidate to do for the current generation of micro EDFs. There would be considerable work involved to make it "right", and I don't mean profile planes or cartoon looking versions that aren't close to the real deal. There are several ME-262s out there in the larger versions, but my questions in the poll are to find out of there would be any interest in a micro ME-262 kit. There are several ways to go about this, but it appears as though vacuum formed fuse halves and nacelles will be the choice if a kit is to be produced. So please take the time to cast your vote as to whether you would be interested in such a kit and if so, the type of power system. There is even the option of props for those that would rather go that route, so please cast your votes. Note that you can choose more than one option.

Problem is I was wondering why the GP 30mm Hyperflow fan was not an option in the poll. at roughly 65-70g thrust (mounted in the F-86), and drawing only 3.7-4.7A, it seems to be one sweet setup. So reserving my vote for later... I would spen the money for a twin motor and EDF setup if it was cool enough.

Thinking outloud. I was mulling over doing a scratch someday soon.

Well that's gonna be tough.
IF trying for any semblance of scale appearance.
First thing one notices on most all Me 262 attempts (in varying degree) is the size of the wastebaskets pretending to be the 262's jet engines,
Cartoon like is a charitable descriptor.
Jumo engines had an 18" inlet diameter in real life.. True!
That means that at 1:12 scale the inlets are 1 1/2" ..38mm !!
Tough to get twin 38mm edfs' to push a 42" span Me 262 convincingly :-) At 1;24 then 19 mm edf's are suggested.
Fill the fuse with a Co2 bottle and run lines/jets as efflux? :-)
An interesting 'problem' nonetheless. Hopefully you can make it work.

DITTO!!!..The power to weight ration of the GP fan is second to none..I would be interested in a kit but the GP fan would get the nod...

Reserving voting until the GP fan system is added...

This is why I targeted using the 27mm AEO fans due to the amount of thrust the high blade count would produce in a small sized nacelle. Based on the CAD drawings, the nacelles look a whole lot better than the larger foamy versions. No huge trash cans hanging under the wings here. It wouldn't be the first time that I was told it something wouldn't work and the end result worked great.

If you have to close the thread, and re-start a new one, 5 posts won't hurt anyone, and WE WILL be back! AEO fan still needs a much larger battery than say a GPHF. It is more the long duct length to EDF diameter that hurts the Me-262 design (been there done that). My 27mm AEO fan in my Micro F-86 is not impressing me now that it can be fired up (static thrust that is). It too has a faily long duct, small diameter.Going to need at least a 380-480mah battery to push the single fan too. At least it does push it along the floor, no wheels, so hoping it will unload in the air! Bigger batter=heavier build.

Here is a screen shot of the CAD work to date. I started with a 3 view of the full scale aircraft and scaled down to a 24" ws. This was as small as I could go and fit fans in the scale "waste baskets". The intakes have been cheated slightly for 100% FSA and a radiused intake lip.

I don't know about anyone else, but I'm really diggin' the look. That is with the UMX fan, not the 27mm AEO. Excellent work John!

Thanks Joe. If the 30mm Hyperflow fan is no more than about 32mm O.D. it will fit inside the nacelle. Not sure what the FSA is on that fan.

Actually, that's pretty good work.
Here's a 3 view to double check against.
Seems a wee bit different, most are though .. no news there, unfortunately.
So what scale is 24" span 1:20?
Given that the original was 13m ~42 ft and 1:24 is 21"

I wasn't concerned with the scale other than to get as small as i could considering the limited power from small fans. I have that and several other drawings. Some make a better transition to a vector, CAD, drawing than others.
