Warning!
1. For maximum performance, it is recommended to position the antenna at a 90 degree angle as
shown in the picture below.
Recommended Position
2. The receiver antenna should not be placed near the engine, metal parts or high current batteries.
3. When using a large number of high-power digital servos in a model, it is highly recommended to
use the SPC feature to insure the receiver always gets the power it needs in high load conditions.
If not, use the system with enough receiver battery capacity.
4. There could be a possible time delay in receiving telemetry data from the HTS-SS (sensor-station)
depending on the conditions in the area you y.
5. It is strongly recommended that you use Hitec ‘s genuine Heavy Duty High Channel Switch Harness with
Receiver Charger Cord (Stock#. 54407S) for all of Optima series of receivers.

1. Function Button
- Used for binding the receiver to a module or Hitec 2.4 built-in transmitters,
entering the FAIL-SAFE or Hold feature.
2. Dual LED Status Indicator
- Indicates the set-up process codes and current status of the receiver.
3. Channel Output and Battery Input Ports
- The ports for battery power input and servos, gyros and other accessories output port are located at the
side end of the Optima receivers.
4. SPC (Supplementary Power Connection)*
- Power the Optima receiver function with up to a 35V electric aircraft motor battery.
Details about the SPC system can be found on page 2.
5. Telemetry Sensor and Data Port*
- A three pin servo plug connector port is featured on the Optima 7 and Optima 9 (not applicable on
Optima 6). Using the HPP-22 PC interface accessory, this port serves to facilitate upgrading the device’s
software and interfacing the optional onboard sensor station.
6. BODA (Boosted Omni-Directional Antenna) System*
- Hitec’s exclusive 2.4GHz BODA System will show you another means of using the 2.4GHz system. This
single antenna with omni-directional booster makes it a whole lot 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. Our Optima 9 receiver features a dual BODA system to give
the added security that larger models need. Installation is easy and simple, just insert the antenna into the
supported antenna holder and stick it to the desired spot you wish to install.
Compatibility
- The OPTIMA & MINIMA series of receivers are compatible with transmitters using Hitec’s 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
- The positions of the servos and other accessories can be set with a FAIL-SAFE point, if power to the receiver is
lost. See page 2 for details.
Low Onboard Battery Warning Function
While you are ying, you will know when the on-board battery is low with a warning alarm from the transmitter.
Review the Low Battery alarm features that use direct telemetry feedback to your transmitter on page 2.
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 a
regulated Li-Po battery. The jumper is removed when the receiver is powered using the SPC feature as
described in more detail on page 2.
*These functions/ features are only for the OPTIMA series of receivers.
Receiver Connection Diagrams
-To see a receiver connection diagram for the SPC feature, see page 2.

Hitec’s exclusive optional receiver power system allows you to directly power the receiver from the main
power battery of an electric powered aircraft. Up to 35 volts can be fed directly into the receiver to power
JUST THE RECEIVER FUNCTION. It will not power the servos. Almost all servos will burn up if more than 6 volts
are used over a short period of time.
- Some Hitec servos are rated to be used at 7.4 volts. You will still need to supply power for your
servos with a four or ve-cell NiMH receiver battery or a 2-cell Li-Po and regulator set-up.
- The SPC system was partially created to be integrated into future Hitec telemetry system devices.
Note
Check the Hitec website for more information on the availability of telemetry systems in the future.

Note
Link (ID-Setup or Bind)
Your Hitec AFHSS system uses a communication protocol that links and binds the Hitec 2.4GHz receiver to
your transmitter. Once the receiver and module are “bound,” no other transmitter can interfere with your
receiver during its operation. In the case of multiple model memory transmitters, you can bind as many Hitec
2.4GHz receivers to your transmitter, one per model memory as necessary.
Each module and receiver set is paired at the factory for your convenience.
Use one of the following binding methods to bind additional Hitec 2.4GHz receivers to your transmitter.

FAIL-SAFE and Hold Mode Setup
If the receiver signal somehow becomes interrupted or interference occurs, the servos will move to the pre-set
FAIL-SAFE point you previously stored in the FAIL-SAFE set-up. Make sure you set the FAIL-SAFE function
properly.
If FAIL-SAFE has not been activated, the signal will switch o after the HOLD period of one second. This means
that the servos become “soft” and remain in their last commanded position under no load (this may equate to
full-throttle!), until a valid signal is picked up again.
In the interest of safety, we recommend that the FAIL-SAFE function should always be activated, and the
FAIL-SAFE settings should be selected so as to bring the model to a non-critical situation (e.g. motor idle /
electric motor OFF, control surfaces neutral, airbrakes extended, aero-tow release open, etc.).
When blinking stops, the system will temporarily
remember the FAIL-SAFE position. Turn o
the system to save and exit.
Testing the FAIL-SAFE Setting
a. Move the sticks to positions other than the FAIL-SAFE settings and then switch o the transmitter.
The servos should now move to the FAIL-SAFE positions previously stored, after the one second HOLD period.
How to turn FAIL-SAFE O and reactivate the Hold Mode
a. Switch on the transmitter then the receiver. Wait for the system to boot and you have control over the model.
b. Press and hold the receiver function button for 6 seconds and release. After 2 seconds, the RED and
BLUE LEDs will blink rapidly.
c. Immediately press the button once.
d. FAIL-SAFE Mode is now deactivated and HOLD mode is activated.
e. Turn the transmitter o then the receiver o.
f. Turn the system back on to use it.
- If FAIL-SAFE is deactivated, the FAIL-SAFE position settings are also deleted!
- The FAIL-SAFE settings should be checked every time before you run the engine/motor.
Note
Telemetry System
The Hitec Spectra 2.4 Module and Optima Series of receivers feature full telemetry capabilities (except Optima
6) and include a Low Receiver Battery Warning as a basic function.
I. Basic Function: Low Onboard Battery Warning - for All Optima Receivers
When the Optima series of receivers is powered up, it will automatically detect the battery voltage level and
recognize between 4-cell or 5-cell NiMH and NiCd batteries (4 cell < 5.8V < 5 cell).
In case a 2-cell LiPo battery is being used, you can customize the battery warning level by using the HPP-22
PC program.
- When the battery level is safe (4 cell > 4.5V, 5 cell > 5.6V), there will be no change to the LED lights.
- When the battery level is low (4 cell < 4.5V, 5 cell < 5.6V), the BLUE LED glows constantly and the RED LED
will blink fast. You will hear three continuous beeps from the module as a low receiver battery warning.
Upon hearing the beeps, we advise you to land at once.
II. Optional Functions:
GPS, FUEL, TEMP, O-RPM, M-RPM, VOLT, Amp Sensors - Applicable for Optima 7 & 9 Only
- More devices will be available in the future. Check the Hitec website at www.hitecrcd.com for more
up-to-date information.
- The telemetry function is applicable for the OPTIMA series of receivers only
Note
- Low Battery Warning function is only for your reference. The actual battery level could be
dierent. Battery Memory Eects such as Lazy Battery Eect or Battery Memory could aect

the Low Battery Warning function.
- When the 2.4GHz system and HV servos are used together, we strongly recommend using
fully-charged, large capacity battery packs and you must constantly monitor the battery status.
