It seems you can find three channel indoor helicopters almost anywhere these days. You may even have one already. They’re great fun indoors and great for kids, too, but after a while you’ll no doubt want to try some fancier flying that your three channel model won’t quite do. Four and six channel helicopters give you more precise flying control. When it comes to channels, more usually is better! Four channel models are usually also coaxial designs so they are pretty stable and they also give you better hovering control. Novices can start with four channel models rather than three channel ones, but the three channel ones are just so cheap these days that most people naturally start with one of those instead. Most people will need a little more patience with four channel flying – hey, there’s no free lunch here!
What are some nice four channel remote control helicopter models you can get? Megatech has a fun coaxial House-Fly indoor helicopter with 2.4GHz radio. Align, famous for their high end T-REX models, now has a T-REX 100 four channel fixed pitch heli that is great, too. It has a single rotor blade with a flybar. it also has elastic landing skids, so it is hard to break the landing gear.
