- Do you like the good looking Expert Helicopters, but you think you are not ready for it yet? Try the new helicopter from Walkera - presenting the CB180D. You get Co-Axial Helicopters feels-like handling, very easy to hover. The CB180D looks just like a Expert Helicopter, very small size that no longer than your computer keyboard, using Fixed Pitch Blades, Hiller stabilizer bar (common design for RC helicopters), a High Power Main Motor + Tail Motor combination, Shaft Driven Tail Rotor, making the CB180D very easy to hover and flying around. Basically it is a advanced design from the Walkera 4#3B, we tested this model and the feeling is pretty much like the 4#3B, so we would say if you are ok to play with the 4#3B, you are ok to play with this beautiful scale fuselage Helicopter.
