funny you should mention the havoc heli. that was what actually got me interested in this hobby too. It's an amazing little machine...but it really isn't much more than a toy. Once the preinstalled battery goes bad you just have to throw your havoc heli away [&o]. You'll have lots of outdoor fun flying a coaxial rotor helicopter outside. But just remember...wind is a bad thing when you are attempting to learn to fly something new. Pick a calm day and you won't have any crashes that keep you from flying.
