"Small" helicopters actually come in a number of sizes. Whether you're looking for small real helicopters that can carry one to two passengers or small radio controlled helicopters that you fly just for fun, finding small helicopters for sale is made a lot easier by the Internet.
Used is cheaper
Depending on what you want, it's usually cheaper to find small helicopters for sale used rather than new. With that said, though, you can get just about anything you want online through auction sites like eBay, ads, or enthusiast forums.
Buy local if you can
No matter what type of helicopter you buy, it's a good idea to buy local if you can. That way, you can find what you want and see it before you buy. And although small radio controlled helicopters can certainly be sent by mail easily, you're not going to want to try to buy those that actually transport passengers over the Internet and have them shipped to you. You are going to want to go see what you're thinking of buying for yourself before you actually purchase it, so that you can make sure it is in good shape, mechanically sound, etc.
Find a local enthusiast's club
You can also get a good idea of what you should be buying by contacting a local small helicopter enthusiast's club. There might be one in your area that welcomes new members. If you have one close by, check it out and ask for information about best models before you purchase.
Buy a kit
Whether your pleasure is to fly a small radio controlled helicopter or one that can actually carry people, you can buy small helicopters for sale in kit form and then put them together yourself. This is also an inexpensive way to buy the type of helicopter you want because getting the materials and then putting your helicopter together yourself is also much cheaper than buying a new helicopter that is fully assembled. The nice thing about this is that instead of having to buy local as you might with a fully put together helicopter, you can buy a kit to put together your own helicopter and can purchase it from any legitimate seller. This removes the geographic limitations you might have if you tried to buy small helicopters for sale fully assembled.
If you're a new pilot
Small one-seater helicopters for sale are a great way to fly if you're a new pilot and yet experienced enough to have your license. Take it up, up and away into the blue skies, just your helicopter and you, while you explore new horizons. You won't have room for passengers, but you will have room -- plenty of room -- to think and enjoy some solitude while you explore from your lofty "perch" in the sky. And because helicopters don't need space to take off from or land as airplanes do, in that they can simply do so vertically, you can take them anywhere they are allowed.
