[DigitalVoid]

hey guys im new to this hobby and well i just bought 2 x-ufo made by silver lit and i was wanting to know a if i got a good deal and b if there are any upgrades i could do to these to make them nicer.

ok i got 2 complete sets for 123.00 bucks shipped usd.
extra blade and spare parts galore.

and well theres not much info about them out there so i was wondering what i could do to em to make them better! links would be great as i said i am new and not hip to the lingo lol.. well thanks for any and all info

So 65 views and not one response huh? oh well i figured some one here would know about the x-ufo.. and any upgrades I could find for it.
see the problem is this.. every thing i find on it is in German and when you translate it it sounds garbled and only a little bit sounds coherent.
I DON'T KNOW WHAT THESE SELL FOR..hence why im asking if i got a good deal.
when you try to visit the silverlit site you can only view the first age and almost all info about these are videos of them flying.. I haven't found 1 useful piece of info about them any where..
are they hard to fly? are they easy or hard to maintain? just general knowledge stuff is all im looking for.
