RE: Would you buy a Walkera heli again?
YES!
I received my 2nd W#36 couple days ago, this one comes with brushless/esc/12C 1800maH lipo.
After spending couple evenings to check and re-setup this bird. I am please to tell you guys that Walkera did improve some of the parts and flys great after some adjustment, but sorry to say it is not a true RTF. The right control stick in the Tx is out of wag, the stick is jammed to the left side and won't return to center position. This is the 5th one I experience having the same problem, very poor workmenship and quality control in the Tx part, fortunately it is an easy fix, undo the 4 screws in the back cover and you can line up the joystick in its axle holder.
This one comes with a new gyro, part #G006 and has a "new AVCS" label at the back. I had a 10 minutes very stable hovering, the tail is rock solid and very responsive to rudder control, I'm surprised that not a single gitch in the entired 10 minutes.
I'll give it a 8.5 (would be 10 if I don't have to repair the Tx stick)
