After reading all the horror stories about crashes, I wonder whether if it is wise to buy a less expensive MR just for practising or indoor flying? This weekend my P3A almost crashed after hitting a small hanging branch. I was flying with prop guards at a challenging location. It was close to the ground, so no real damages (only a prop), but I could have easily lost it. I am thinking about buying a much lighter and cheaper spare MR. Any recommendations and tips?
