You won't find many ARF's where helicopters are concerned unless you go with a cheap RTF setup. Most (quality) helicopters are sold as kits. It would be benifical to build it from scratch as you'll gain an understanding of the mechanics, and you'll know how to fix it when you (inevitably) crash.

I understand that you want to use the joker as a camera ship. It's a great choice, but well, VERY expensive.
Helicopters are not really something you just "fly". It's not so much like an airplane where you can fly it even if you have no operational knowledge of aircraft. Helicopters require almost a degree of obsession to build, maintain, and operate (safely). The skillset needed to fly them is completely different aswell. The only thing that transfers over from flying aircraft is positional orientation, which is one of the biggest hurdles for most newbie pilots anyways, so you're set in this regard, now you just need to re-train your reflexes.

That said, I would, like everyone else, suggest you stay away from such an enourmously expensive helicopter if you're a beginner, and instead learn on a smaller ship. You don't nescesarily need to go the micro route, but it would be the cheapest in the long run probably, as repairs on them are very cheap. The best in this range is arguably the Align T-rex or the X-400. If you don't mind spending a bit more, you can go with a mid to full size setup such as the Mikado Logo 10/14/20 or Ikarus eco-8. The bigger you go, the easier they become to fly, the more expensive they become to build, and the more expensive they become to crash.

In the joker's case, JUST the motor can cost you $300 - $600. All of the above mentioned helicopters have belt driven tails aswell.

I would suggest a micro like the t-rex if you're learning. The initial flight learning curve will be a bit steeper as they aren't AS easy to control, but if you can master the t-rex, flying the joker would be a walk in the park, so to speak.
