The SuperSwitchHD is a DSC style switch designed for the demands of large scale aircraft. Standard switches with their 22 gauge wires and single R/C connectors are just not sufficient for 1/3 scale aircraft up. Even with dual receivers in the 40% and larger planes the current draw from the battery through the switch can be substantial during maneuvers. Standard R/C connectors can drop up to a volt with a 9 amp load through them.  When you consider a high-torque digital servo can draw up to 4.5 amps and you may have 6 to 13 of these in an aircraft a current draw of 9 amps is not unusual.  This means through two connectors and the switch contacts you can loose up to 3V between your batteries and receiver with a standard heavy duty switch at a 9 amp load.  While this may be momentary this is when you need the least voltage drop to the servo as voltage supplies the servos’ torque. Reduce the voltage the servo sees and you reduce the torque the servo can supply.  While you still have the switch contacts causing some voltage drop the SuperSwitchHD eliminates any voltage drop across the conectors since the Deans Ultraplugs have negligible voltage drop at 20 or 30 amps.  

The unique features of this switch are the 18 gauge wire on both the input and output with high-quality Deans Ultraplug connectors.  It is designed for use between batteries with Deans connectors and one of our Regulators, PowerExpanders or PowerSystems with Deans inputs.  Note: If you convert to standard R/C plugs to go into a receiver you loose some benefits of this switch although it does allow you to put 3 or 4 R/C connectors on the Deans to connect to your receiver if you have the open ports to support the extra battery connections.

NOTE: Battery Pigtail and Shrink-wrap are no longer included in the package.
