Ready to fly (or RTF) planes come as pre-assembled kits that usually only require wing attachment or other basic assembly. Typically, everything that is needed is already in the kit. RTF planes can be up in the air in just a few minutes and have all but eliminated assembly time (at the expense of the model's configuration options.) Among traditional hobbyist builders, RTF models are a point of controversy, as many consider model assembly, fabrication and even design as integral to the hobby. If you are looking for the most advanced electric RC planes, get the 4-channel brushless-powered or RC jets with electric-ducted fans. For Beginners, Our Pilots Recommend Starting With A Two or 3-Channel Airplane.
