If you have the time and money to invest. Also, if you can provide top notch customer support, can design your own parts, then it would be a good idea. Not to mention, pay the taxes for your own business as well as your own medical insurance.... hehe

That sounds like a cool plan. I would love to have my own business selling RC related items, but the time and money needed to set up a business is a serious issue.
