The 2.4GHz system that offers the impossible: Pro-level features at a sport-system price. Some people feel that a 2.4GHz system with a built-in module will always offer better response than a modular system. Nothing could be further from the truth. This is the "Aurora 9" 3 in 1 radio with sophisticated programming for sail planes, helicopters and all kinds of power planes Computer Radio The Aurora 9 is a “pure digital” 2.4GHz system offering immediate response yet it is also compatible with the Spectra PRO for PPM and PCM Operation. The Aurora is a true 3 in 1 radio with sophisticated programming for sail planes, helicopters and all kinds of power planes. The Aurora 9 also features a backlit 5.1 inch touch screen display, 30 Model memory, assignable switches and customizable programming menus. With all these features and a price that can’t be beat, there is no doubt the Aurora 9 will become the radio of choice for the most sophisticated pilots.                                           + Includes: (1) Hitec Aurora 9 9 channel Transmitter with 2.4GHz Spectra Module (1) Optima 7 7channel 2.4GHz Receiver (1) 6-cell 1300mAh Transmitter Battery (1) CG-S45 AC Wall Charger (1) On/Off Switch, Y-Harness, Receiver Foam and Instruction Manual Optima 7 Channel: Features: Adaptive Frequency Hopping Spread Spectrum Technology (AFHSS) Our 2.4G system utilizes the latest AFHSS technology and our exclusive Smart Scan system to ensure a rock solid, interference free connection between the transmitter and receiver.
