These are top of the range EDF radio controlled jet models aimed at intermediate to advanced pilots. They are powered by a brushless motor connected to a ducted fan instead of the usual propeller found on traditional rc planes. This makes them ultra realistic unlike some jet models on the market that simply have a propeller stuck on the back that looks pretty rubbish! The motor is a brushless motor which are far more powerful than the standard brushed ones and push the jets to amazing speeds of 70 mph and even up to 90 mph for the big F-16! All our radio controlled jet models come with a 4ch radio system and everything included to get flying. They are pretty much ready to fly with electronics pre-installed but need some minor construction such as attaching the wings and under carriage.
