Looking for the following, do they exist?

They exist, in varying qualities.

Best place to find info on Luft 46 projekts is www.luft46.com
He has model links at the bottom.

Squadron carries a few manufacturers of such kits, such as:

Planet Models great resin kits-

Special Hobby's mediocre plastic kits -

Dragon/DML made two beautiful Ho229 kits, the fighter and the 2-seat night fighter, in 1/48. But I think they're long out of production.

You can see my Luft 46 builds here:

just wanted to say that it looks like Dragon/DML is re-issuing the 229.
www.greatmodels.com lists the kit on a search and is 'taking pre-orders'
(i searched on "1/48 229" after pushing the 'database' button on the left of the home page)

you could search for your other planes.
i could not find them, but sometimes you need to try variations.

good luck,

Your website is killer!

Of the "paper projects" kits, which would you say to stay away from and which did you love?

I have noticed on eBay the DML Horten 229 is coming back, but I can't find a review of the quality, how was your experience?
