Kill Switch will activate under three conditions:

  • Manual AUX Channel Button Kill from Remote (must assign Aux 1 or 2 on Remote)
  • Total Voltage Loss or Low Voltage under 3.0 Volts (should never reach this unless loss of a cell or cells)

Simple Design:

  • No dip switches
  • No parameters to choose
  • Simply connect to ignition coil and receiver and set AUX channel

Dimensions: 16x19x14 mm (believe to be the smallest footprint- less then a nickel in comparison)

Trust is key and if the MOD Racing Kill Switch does not respond or perform its kill function properly simply send it back and we will refund your purchase price of item.

Why Now?

Came out of necessity as many of the major brand kill switches we have seen throughout the years have experienced being untrustworthy and would kill the vehicle without cause creating doubt. (We tried many as well, none were 100 over 100)
With doubt in many peoples minds, many would rather risk run away then lose a race due to an unworthy kill switch shutdown.

Runways can happen at any time for a plethora of reasons.

Throttle servo failure, battery loss with throttle in open position, carburetor butterfly failure and mechanically sticks open, throttle bar failure, rock stuck in throttle bar, receiver failure, etc.

Needed For 5th Scale Racing to Grow:

A run away 5th scale is a huge liability and having a reliable source of control over its shutdown at any point in time is a needed feature that we all need to have in order for us to limit the liability of racing this size of vehicle.

With a reliable racing kill switch this expands our horizons for new venues and gives people more of a sense of security that their race rig will not be destroyed at a drop of a pin.

Cheap Insurance.

A run away car can cause hundreds and sometimes thousands of dollars worth of damage to both the rc vehicle itself and to other peoples property. And in the unfortunate event it can also cause physical harm to people if caught in its path.
