More than I can say about WoW Hobbies.  I recently ordered a 250 heli that came in with a defective swash bearing.  They really expect me to ship them back the swash so they can inspect it before sending out a new one.

I told them to just forget it...Id buy a new swash elsewhere.  I mean its a 12 dollar part that they probably have 2 or 3 dollars in and they cant take my word for it?  I even supplied pictures of the part.

While I havent ordered much from Tower Hobbies, I can definitely say I am satisfied with their customer service...and Im sure they will take care of you too!
