RE: Kit or RTF????
Formula.....the mSR is EASY to fly....even though its a fixed pitch and not coaxial. Where the crashes come from are trying to do to much....getting "crazy" with it. But for learning to fly it's a great little indoor heli and and its super DURABLE....which is important for a beginner. When I bought mine I bought a bunch of extra parts that Ihave never used because nothing ever seems to break. Another good thing about is ....as you get better with your flying skills....you can get going pretty fast with this heli.
