9 CHANNEL 2.4GHz AIRCRAFT COMPUTER RADIO SYSTEM
Hitec 2.4GHz Optima and Minima Series Receiver
6. BODA (Boosted Omni Directional Antenna) System*
- Hitec’s exclusive 2.4GHz BODA System will show you another way of using our 2.4GHz systems. The single Omni-directional antenna
booster makes it much easier to install the 2.4GHz antenna. Intensive tests have proven that the single BODA system in our 6 & 7 channel
systems is better than or equal to our competitor’s dual antenna systems while our Optima 9 receiver features a dual BODA system to give
the added security that larger models need. Installation is easy and simple, insert the antenna into the supported antenna holder and stick
it to the desired spot you wish to install.
Compatibility
- The OPTIMA & MINIMA receivers are compatible with transmitters using the Hitec AFHSS 2.4 GHz system, such as, Spectra 2.4 module
or dedicated built-in module AFHSS 2.4 Hitec transmitters.
FAIL-SAFE/Hold Mode Selectable
- Servos and other accessories can be set with a FAIL-SAFE point, if power to the receiver is lost.
Low Onboard Battery Warning Function
This function lets you know when the on-board battery is low with a warning alarm from the transmitter while you are flying.
Review the Low Battery alarm features that use direct telemetry feedback to your transmitter.
Jumper*
The jumper is installed at the factory and is used when the receiver is powered by an electronic speed control, a commercially available
B.E.C. (battery eliminator circuit), dedicated 4.8 to 6V. NiMH battery pack, or regulated Li-Po battery. The jumper is removed when the
receiver is powered using the SPC feature.
*These functions/ features are only for OPTIMA series receivers
