Ideal for anyone who plans to expand their large model collection, this value for money triple pack makes perfect sense. Featuring two of Hitec's exclusive Boosted Omni-Directional Antennas the Optima 9 offers for belt-and-braces safety and with it, valuable peace of mind. Independent testing has proven that the dual BODA system used in the 9-channel receiver is equal to, or better than, the remote receiver or quad antenna systems used by Hitec's competitors. Offering a full telemetry capability and utilising a slimline end-port design, the Optima 9 adopts Hitec's Adaptive Frequency Hopping Spread Spectrum technology (AFHSS) to ensure rock-solid interference-free operation. Furthermore, with Hitec's Supplementary Power Connection (SPC) you can eliminate 'brown-out' concerns by powering the receiver independently of the servos.
