Gecko-ZTW 85A SBEC 8A...
      This is a top quality, effective brushless electronic speed control with an integrated switch-mode BEC. It can run without the requirement for a seperate receiver battery to power your servos and receivers, conserving you weight and complication. GECKO series likewise consist of ESC OPPTO for huge flying. This series of ESC likewise features an exposed, finned heat sink aluminum case with light-weight plastic endcaps. Additional features consist of safe power arming along with sophisticated programmable, information logging system, low voltage cutoff, braking, timing, throttle input variety, and more, making this series truly a pro series speed control.

      As the development of the electronic and popular demand of the marketplace, our BEC has been specifically designed for severe aerobatics and therefore has the capability to support the higher existing applications to eliminate the possibility of unwanted shutdowns, and is likewise capable of supporting constant simultaneous numerous servo operations generally found in CCPM geared up hardcore 3D E-helicopters.

Remark ZTW A-Series’s ESC enables you to set all functions to fit your particular needs, that makes it extremely effective and user friendly:1.User programmable brake setting (we suggest utilizing brake for just folding props applications)2.User programmable battery type(LiPo or NiCd/NiMh)3.User programmable low voltage cutoff setting4.User programmable factory default setup bring back  5.User programmable timing settings (to improve ESC performance and smoothness)6.User programmable soft velocity start ups (for fragile gearbox and helicopter applications)7.User programmable guv mode (for helicopter applications)8.User programmable motor rotation(clockwisecounterclockwise)9.User programmable switching frequency10.User programmable low voltage cutoff type (power reduction or instant shutdown)Settings:1.Brake: ON/OFF* ON- Sets the propeller to the brake position when the throttle stick is at the minimum position (Advised for folding props).* OFF- Sets the propeller to freewheel when the throttle stick is at the minimum position.2.Battery type: LiPo or NiCad/NiMh* NiCad/NiMH – Sets Low Voltage defense threshold for NiCad/NiMH cells.* LiPo – Sets Low voltage defense threshold for LiPo cells and automatically detects the number of cells within the pack.Note: Picking the NiCad/NiMH alternative for the battery type, activates the ESC to automatically set the cutoff threshold to the factory default of 60%. The cutoff threshold can then be consequently changed through the Low Voltage defense function, if required. The ESC will read the preliminary voltage of the NiCad/NiMh pack once it is plugged in and the voltage read will then be used as a reference for the cutoff voltage threshold.3.Low Voltage Defense Threshold ( Cutoff Threshold ):Low / Medium / High1) For Li-xx packs- number of cells are automatically determined and requires no user input apart from defining the battery type. This ESC offers 3 setting options for the low voltage defense threshold ; Low (2.8V)/ Medium (3.0V)/ High (3.2V). For instance : the voltage cutoff options for an 11.1V/ 3 cell Li-Po pack would be 8.4V (Low)/ 9.0V(Med)/ 9.6V(High)2) For Ni-xx packs-low / medium / high cutoff voltages are 50%/60%/65% of the preliminary voltage of the battery pack.. For instance: A totally charged 6 cell NiMh pack’s voltage is 1.44V x 6=8.64V,when “LOW” cutoff voltage is set, the cutoff voltage is: 8.64V x 50%=4.3V when “Medium” of “High” is set, the cutoff voltage is now 8.64V X 65%=5.61V.4. Bring back factory setup defaults:   Bring back- Sets the ESC back to factory default settings;    Brake:                            OFF   Battery type Detect:              LiPo with Automatic Cell   Low voltage Cutoff threshold:     Medium (3.0V/60%)Timing Setup:                     AutomaticSoft Velocity Start Up:        Soft AccelerationGovernor Mode :                  RPM OFFFrequency :                       8kHzLow Voltage Cutoff Type:          Lower power5.Timing Setup :  Automatic/ Low / High.*  Automatic (7-30 deg) – ESC automatically figures out the maximum motor timing*  Low (7-22 deg) – Setting for many 2 pole motors.*  High(22-30 deg)-setting for motors with 6 or more poles.In most cases, automated timing works well for all kinds of motors. Nevertheless for high performance we suggest the Low timing setting for 2 pole motors (basic in-runners) and high timing for 6 poles and above (basic out-runners). For higher speed, High timing can be set. Some motors require different timing setups therefore we suggest you to follow the maker recommended setup or utilize the automated timing setting if you are unsure.Note: Run your motor on the ground first after making any changes to your motor timing!6.Soft Velocity Start ups: Very Soft / Soft Velocity/ Start Velocity * Very Soft – Offers preliminary sluggish 1.5 sec ramp-up from begin to full rpm planned to protect fragile equipments from removing under instant load. This setting is recommended for either set wing models geared up with transmissions and / or helicopters.* Soft Velocity- Offers preliminary sluggish 1 sec ramp-up from begin to full rpm. This setting is recommended for either set wing models geared up with transmissions and or helicopters.  * Start Velocity – Offers quick velocity start ups with a direct throttle action. This is recommended for set wing models fitted with direct drive setups.7.Active RPM Control (Heli Guv mode)* RPM Control OFF* First Range:  There will be a 5-second delay from begin to full rpm,  however if the throttle is cutoff after beginning, then the next start will be as typical start.* Second Range: There will be a 15-second delay from begin to full rpm, however if the throttle is cutoff after beginning, then the next start will be as typical start.Note: Once the Guv Mode is made it possible for, the ESC’s Brake and Low Voltage Cutoff Type settings will automatically be reset to Brake Off and Lower Power respectively despite what settings they were formerly set.8.Motor Rotation: Forward/ ReverseIn most cases motor rotation is typically reversed by swapping 2 motor wires. Nevertheless, in cases where the motor cables have actually been directly soldered the ESC cables, motor rotation can be reversed by changing the value of setting on the ESC.9.Switching Frequency : 8kHz/16kHz* 8kHz – Sets ESC switching frequency for 2 pole motors, e.g. in-runners.* 16kHz – Sets ESC switching frequency for motors with more than 2 poles, e.g. out-runners.Although 16kHz is more effective with our Thrust motors, the setup default is 8kHz due to the higher RF sounds caused at 16kHz.10.Low Voltage Cutoff Type : Lower Power / Difficult cutoff * Reduce Power – ESC decreases motor power when the pre-set Low Voltage Defense Threshold value is reached. (recommended)* Hard Cutoff – ESC instantly cuts motor power when the pre-set Low Voltage Defense Threshold value is reached.Programming Mode Audible TonesProgramming Mode Audible Tones ESC Functions           Throttle Calibration                                         (within the first 4 Sec )??  ??  ??  ??1              Brake            _ *  _ *  _ *   _ *   Brake On /Off2               Battery type                                         ~  ~  ~  ~   NiCad        ~~   ~~   ~~   ~~   LiPo3          Low Voltage Cutoff Threshold                           *_ _*  *_ _*  *_ _*  *_ _*   Low2.8V/50% *_ _ _*  *_ _ _*  *_ _ _*  *_ _ _*  Medium3.0V/60%*_ _ _ _* *_ _ _ _* *_ _ _ _* *_ _ _ _*   High3.2V/65%4      Restore Factory Setup Defaults                                     —  — — —   Restore5             Timing Setup                        –  –  –  –   Automatic (7-30°)         ––  ––  ––  ––   Low (7-22°)     –––  –––  –––  –––   High (22-30°)6           Soft Velocity Start Ups                                 ∨∨ ∨∨ ∨∨ ∨∨   Very Soft           ∨  ∨  ∨  ∨   Soft Velocity    ∨∨∨  ∨∨∨  ∨∨∨  ∨∨∨   Start Acceleration7            Guv Mode                                           _*_  _*_  _*_  _*_   Rpm off         _**_  _**_  _**_  _**_  Heli first variety       _***_  _***_  _***_  _***_  Heli second range8             Motor Rotation                                    W  W  W  W   Forward/ Reverse9           Switching Frequency                                       //  //  //  //   8kHz                     16kHz10         Low Voltage Cutoff Type                                           _¯_¯_¯_¯   Reduce Power         ¯_ ¯_ ¯_ ¯_   Difficult Cut Off
