A trusty 40 amp budget speed controller from Hobbywing with a relatively powerful 3 amp linear BEC to power your receiver and servos. To keep costs down, connectors are not included however hobbywing have focused on the important bits and used top quality components throughout. The input wires are 12AWG and the three motor wires are 14AWG. SkyWalker series speed controllers have a number of protection features built-in and a number of options can be programmed either from your transmitter or with the optional LED programming card.

Most importantly, these controllers have support for the following features, which help ensure a long service life:-

  • Low voltage cut-off (LVC)
  • Abnormal input voltage
  • Throttle signal loss
  • Thermal cut-out in case of overheating (usually caused by drawing too much current!)

This 40A version can support burst currents of up to 55 amps, so there's a reasonable amount of headroom here.

For use with 2s or 3s lithium polymer batteries. Always ensure a good airflow in your model aeroplane to keep your ESC operating cool and efficient.

Made in China.
