A $3.00 prop is much cheaper than a $50.00 receiver and the damage that broken receiver will cause when it destroys your $150.00 airplane and your $100.00 engine or the damage it could cause if it fails in flight and hurts somebody or destroys property.

Do yourself a favor.. just replace the prop. An APC 12-7 is about 3 bucks at our local hobby shop.
