No one is criticizing you. Its not a tough crowd, well sometimes maybe, but not that I've seen on this post. They are just trying to help you, and are concerned you might hurt yourself. Actually I think they are being very nice. RC Planes & helicopters can be a great deal of fun, if approached the correct way and in a safe manner. They can also be extremely dangerous. Anyway don't take anything personal here. Like I said they are trying to help you, not criticize.
