Anyone knows anything about this German mfg and this plane? I am looking at their Extra 300 S 170cm (67 inches). This seams to me to be the nicest Extra I can find for my OS 120 pumped. Eventhough a very expensive kit selling for €450-500 (US$570-630) one is hoping they are worth it???

Well, all I can say - bed story!
I bought Su 26 kit basing on the kit kontent described in their web page. In spite of this there were no spinner, no canopy frame, and no kevlar. Only the price was right....
I made a claim, wait over one month and finaly after few phone calls I got the answer: they will not deliver the canopy frame - I should make by my own, there is no kevlar and there will be no spinner as well....Very nice!
The only positive result is that they have changed description in their web page day before yesterday.
I know the guy who has bought Gee Bee in this company and still is waiting for landing gear...
So, be carfull. Kit is no bed, but you can not compare it with Comp Arf quality! Absolutly no - for the same money you are getting in CA outstanding quality and of the model and hardawre. It is also much more work, comparing with CA models.
I am just working on Su - 26 - should fly in the early spring - let you know if you like

I bought their ME-262 from someon on ebay, and the plane wa super nice.

I then ordered the landing gear from airworld for it, and it took 3 months to get....and they sent me the wrong gear. [:@]
Comunication via email was a pain. Only replied on 1/3 of my mails, and about a month in between.

Im not buying anything directly from them again.
It will have to be from a dealer or something.

The jet kits are realy nice, but the instructions suck, and there is a lot of building and figuring out stuff to do.
