Any reason why you don't want to use a USA site? I'm sure they'd ship to the UK? You might want to check out www.towerhobbies.com to shop around and see what is available- then maybe look for a local store that carries what you determine you want. TT-01D is probably available in kit form for less money, and if you're OK with putting it together, you'll learn a lot about how the TT-01 works. This is helpful for later if you ever need to repair it, or if you want to install upgraded parts. You'd of course need to supply the electronics (the kit would come with a motor, but you'd need to supply the receiver, servo, transmitter, ESC, etc.) Some kits come with a ESC, so shop around.
