Hitec RCD FLASH8 2.4GHz Radio Control System User Manual

Intro.

Thank you for purchasing the FLASH 8 transmitter. FLASH 8 is composed of diverse features to maximize customer’s R/C experiences. Please read

carefully to become familiar with FLASH 8 under your control. After reading this, please keep this manual for easy reference.

Product Specifications

- Frequency Range : 2.4056GHz~2.4776GHz(Opti-Mini), 2.406GHz~2.480GHz(S.L.T)

- Modulation : Frequency Hopping Spread Spectrum (FHSS)

- Tx Power : Max. 100mW

: Optima FHSS 2.4GHz receiver is used with the Hitec FHSS 2.4GHz module.

- New Gimbals Stick

: The Gimbal of FLASH 8 is used the four ball bearings for high-end controller so you can feel very smooth stick experience.

Gimbals sense of this soft key will pass to the user’s object immediately then offer the best control touch to you.

- Switch Settings

: User can use the variety switches that given the special features on the FLASH 8 to suit for convenience.

The role of switch is very important to set the variety Mixing function of the plane and FLASH 8 designed on intuitive environment for

setting that function. Please read carefully this manual from the beginning to the end.

- Channel and function settings

: FLASH 8 set to suitable primary channel functions automatically when you select the models such as Helicopter, Airplane and Glider and this

Features of OPTIMA Series Rx

OPTIMA 6, 7 receivers are compatible with built-in FHSS 2.4GHz module of FLASH 8 and They have many necessary functions for the 2-way

communication radio control.

- 2-way communication sensor and System terminal

: The sensor station collect the data that 2-way communication sensor sent and Data is transferred to the FLASH 8 through the data 3pin of

OPTIMA7 receiver. You can upgrade the software of your Tx or send data of your sensor station to the PC if you extra purchase the HPP-22.

- Function Button

: OPTIMA receiver and built-in FHSS 2.4GHz module are used to set Fail-Safe/Hold function.

- Display Dual LED status

: A Jumper of Rx is mounted in the factory and It is used to supply power by the general BEC(Battery Eliminator Circuit) of electronic

transmission or 4.8 to 6 volt Ni-MH battery pack or battery Li-PO 2Cell.

(Warning – The Servo ability is different according to the part of regulator capacity and stable power supply of receiver. Please check this

always.)

- Normal / Scan mode selection

: You can select Normal / Scan mode by 2.4GHz signal type..

- Fail-Safe Specifications

: This function is operating servo or peripheral on Fail-Safe status if signal of Tx is quit.

- The following figure illustrates the wiring that BEC supply power to Rx and servo also the Electronic transmission supply power to the motor.

- Use the BEC when servo current consumption exceeds the current that supplied by ESC.

- (Warning – Please following this procedures whenever put the power to the transceiver system.

- Power ON: Power on the Tx first then power on the Rx next.

- Power OFF: Power off the Rx first then power off the Tx next.)

Pre-flight checks

Please put the power to follow above warning order before use the engine or motor. And flight after check that all servos operate smoothly.

Range Check

OPTIMA Rx due to additional planes.)

6. Now, you can steer object in normal mode that Tx and Rx are connected.

(Warning – Available LINK range of Tx and Rx is between 45cm and 5M. If LINK cut off more than 1 second because of the external

environment in the Scan Mode or one of transceiver’s power is turned off, you have to turn off both the Tx and Rx then LINK again.)

Transmitter Scan Mode

1. Press and hold the Back button and Menu button at the same time then go to the menu screen after turn on the power of FLASH 8.

2. Turn the Menu button then go into SPECTRA Menu then select the type of Rx then Scanning.

Fail safe and hold mode

When Rx signal take effect on external influence if you set the Fail - safe mode, the servo will go to Fail–safe position you stored already. The servo

will turn off the power for 1 second in hold time if you didn’t enable the Fail–safe mode. Then the servo will keep no-load condition and move to the

position that is ordered last time until it detects a normal signal again. Always, the Fail-safe mode must be enable for safe flight and the Fail-safe

mode is required safe flight status like the engine idling, the motor stop, extended air brake, etc.

Always, It is very important to check the transceiver’s signal and range are normal or not before flight. Unlike FM/PPM and PCM, It is impossible to

verify the range of transmission to fold the antenna because the 2.4GHz antenna of Transceiver is short and fixed. Hitec 2.4GHz system can reduce the

signal strength of transmitter by force to use the Power-down mode. The Power-down mode reduces the range up to 30 meters. Please check the

minimum distance more than 30 meters between the Tx and Rx then make sure the Tx and Rx work normally in the Power-down time.

3. Check the minimum distance more than 30 meters between the Tx and Rx then make sure the Tx and Rx work normally in the Power-down

Receivers of Hitec FLASH 8 and OPTIMA series built in the 2-way communication model to detect the voltage level automatically after Power on.

And there are GPS, temperature, oil flow and RPM sensors in 2-way communication product (However, OPIMA6 can not mount 2-way communication

Option sensor.)

- The battery voltage is low, the alarm sounds. Please check the battery voltage immediately if you here a beep in flight.

SPC System

You can enjoy this SPC system only in Hitec Products. This auxiliary power system will supply the battery power to the SPC directly so the receiver

can always keep stable status in emergency situation. The SPC can be supplied up to 35 volts directly from the power battery. Never supply the power

to the Main Battery terminal of Rx. This is a description about the auxiliary power system that to supply power to the SPC terminal of the OPTIMA

receiver. Usually almost Servos will burn if the Main Battery terminal is supplied 35 volts.

( Note – Some of the High voltage servos need 7.4 volts in Hitec Products. Therefore you need 4 cell Ni-MH or 2 cell Li-Po receiver batteries and

Rectifier device for setting. SPC System is applied partially to the Hitec 2-way communication wireless remote control system.

Warnings and Precautions

- Don’t steer this in the rain and on the standing water.

- Don’t steer this after drink alcohol.

- Always check the remaining battery power.

- Always power on the Tx first then power on the Rx next to prevent failure.
