I have a part on my heli that I'd like to modify, I'd like to get a patent put on it. I was wondering if someone had stories to tell about a patent or what steps i should take to protect my idea. Should I trust those tv advertisements that say they'll help you or will they take me to the cleaners? If anyone out there has advice on the patent process. I'd love to hear it.

If a guy can put some velcro on his shirt, slap a baby bottle to it, and make millions doing it. The sky's the limit.

thanks in advance.
