This radio is only slightly more expensive than a standard 4-channel entry level setup, while offering a lot more advanced features. Of course, you can always get a nicer radio for more money. A top-quality 8-channel setup with glider and helicopter functionality and a complete feature set is available with the Airtronics RD8000, which is about $100 more expensive than the JR Sport SX600 system. Both of these radio systems are fantastic values when compared to anything else in their price ranges.
