Rich,
I have had one of those chinooks, and a friend has one now, we fly all sorts of helis, forget taking that chinook outside unles absolutely dead calm, with 8 rotor blades spinning it creates a big downwash which upsets the heli in the very slightest of breezes, also the large long body is greatly affected by breeze, its definitely a church hall heli, its too big for the living room, due to downwash, and balancing front and rear yaw is very tricky .
Best by far I have had was the esky fixed pitch honeybee, for indoor hovering, and outdoor flying, dead easy to maintain and set up, cheap parts, and loads of upgrades, most of the indoor, and it was a good learning tool for bigger helis. check out heliguy.com forum for info on all sorts of helis, electric, indoor and outdoor, I would go for the blade mcx, somewhere on google a guy has it inverted and stuck on a ceiling! very cool!
