When I think of RC models I think of ultra light construction. I also think of basics like bubble canopys and single props. These are my favorite. Its not that I prefer the bubble canopy, but in its design I think the asthethics work well.

Basic RC

Hover
Hover
Hovering is the most challenging part of flying a helicopter. This is because a helicopter generates its own gusty air while in a hover, which acts against the fuselage and flight control surfaces. The end result is constant control inputs and corrections by the pilot to keep the helicopter where it is required to be. Despite the complexity of the task, the control inputs in a hover are simple. The cyclic is used to eliminate drift in the horizontal plane, that is to control forward and back, right and left. The collective is used to maintain altitude. The pedals are used to control nose direction or heading. It is the interaction of these controls that makes hovering so difficult, since an adjustment in any one control requires an adjustment of the other two, creating a cycle of constant correction.

Mini Mini
At just 4.5 inches long, the tiny-sized MX1 chopper is the world's smallest remote controlled R/C helicopter. Just $49.99 from Think Geek
RC Apache
I almost had to laugh, Im not a fan of the dubble blade on the rotary, I think it looks heavy and clumbsy, But what are you going to do. Its a mini.

Sparrow Hawk
SCI-FI meets reality
French inventor Paul Cornu designed and built a Cornu helicopter that used two 20-foot (6 m) counter-rotating rotors driven by a 24-hp (18-kW) Antoinette engine. On 13 November 1907, it lifted its inventor to 1 foot (0.3 m) and remained aloft for 20 seconds. Cornu's helicopter would complete a few more flights and achieve a height of nearly 6.5 feet (2 m), but it proved to be unstable and was abandoned.
