You'll be making a pretty expensive mistake starting right out with a scale helicopter (although that somewhat depends).
Start out at Helicopter world:
http://65.215.192.230/Merchant2/merchant.mv
You CAN get some fairly inexpensive .30 scales there.
As far as I know, there's only 1 place in the UK that makes Apaches (.60 sized). For attack choppers, the Airwolf seems to be the most common. Then there's Cobras and Tigers.
I'd recommend buying a Hawk for starters. Learn on it. Then you could get yourself one of the Century or Hirobo .30 sized scales that come as a complete kit. Then move up to whatever...
