The DX6i is an excellent choice for sport modelers who want to harness the power of a programmable transmitter, without paying for advanced features they wont use. The software offers compatibility with both airplanes and helicopters, as well as enough memory to store settings for up to 10 different models! The 10-model memory is especially useful if you fly mostly Bind-N-Fly aircraft. The combination of its Simple Scroll interface, easy-to-read LCD screen and simplified menu navigation will immediately put first-time programmers at ease with its intuitive programming. Many programming functions like throttle curves and expo are graphically depicted to give you a clearer picture of the changes you're making. Whatever kind of flying you do, the DX6i can be adapted to most any model in your existing collection that requires six channels or less. Type: Radio System Color: Assorted
