I totally love my
WL V911! For the price, it's simply the most responsive helicopter I own. The ailerons are connected directly to the servo actuators, so rudder and aileron actuation is instantaneous. Full-scale transitions are VERY quick, so for starting pilots this might lead to frustration because you might think it's too "sensitive".
If you don't mind the 2-3week shipping time, banggood.come works pretty well.
Another reason why I like this copter is that you can actually buy it separate from the remote control (less than $20 for a full replacement). After a while when you buy these things, you develop an annoying collection of crappy remote controls. Since most of these run at 2.4GHz, they can be paired with a "master" transmitter. I bought
THIS transmitter that accepts my WL 911, GW 9958, and my Syma X1.
