  • • Power arm protection, over-heat protection, low-voltage protection and lost-signal protection.
  • • Secondary sub-menu setting by LCD program card or PC interface.
  • • Firmware updating by PC interface.
  • • Unique metal shape designing gives your new fashion visual impact.
  • • Super smooth and accurate throttle linearity.
  • • Support and match with most of the motors, including high RPM motors.
  • • Advanced Governor Mode and soft start.
  • • Programmable motor timing.
  • • Utilizes new smaller MOSFET technology to minimize weight.
  • • Finned heat sink.
  • • Programmable throttle input range.
  • • Auto motor shut down if signal is lost or there is interference.
  • • Anti-spark circuit eliminates (HV OPTO version only).
  • • Optional special programing card with LCD (sold separately)

Reliable quality, great performance
Gecko utilizes aluminum canopy, so its appearance is more attractive than other brand. Reduce damage possibility with high load obviously while output violent power. All the components are imported, to ensure high quality and reliability.

Protect your beloved plane
Automatically reduce output power while the temperature reach more than 110℃, recover power while the temperature is under 100℃.
The ESC itself won't startup motor even though radio sticker raised to higher position while power on, in order to avoid motor spin suddenly.

Fast throttle response, more stable
Thanks to technology of sync Rectifier drive power optimization, bring to fast throttle response and linear control experience. Makes flight more stable.

Support upgrading firmware via PC
Customer can upgrade the firmware with ZTW software and program card to get newest functions.

Data memory
ESC can record data of highest temperature of ESC itself and motor, highest rotate speed etc. Customer can read them with LCD program card or wifi module. (sold separately)
