TCW Technologies debuted its SmartStart system at Sun ‘n Fun, adding to its growing inventory of electrical system enhancements for Experimental aircraft. The small SmartStart module is best described as a “remote arming switch” that interrupts the activation of the starter solenoid when it’s not first activated by a momentary contact switch, and then when a one minute timing window expires afterwards. Designed as an additional aircraft theft deterrent, it’s small enough to hide almost anywhere inside or outside of the airplane.The SmartStart also allows for the connection of one or more additional interlock switches, useful to ensure a fully closed or locked door, canopy, cowling, baggage door, or other item before the engine is allowed to be started. All this requires is an additional low-current switch, such as a microswitch, be wired into the 15-pin connector that attached to the module. When the SmartStart is ready to energize the starter solenoid, a red “Armed” light will glow, and then the pilot has one minute to start the airplane before having to activate the module again.Priced at $75 for the SmartStart module itself, an 8-foot wiring harness is also available as an option for an additional $45. TCW has also developed and was showing at Sun ‘n Fun a larger version of its Intelligent Power Stabilizer product. Initially released last summer in 4-amp form, the new module handles twice that current. The device is a DC power conditioner that allows EFIS, engine monitors and GPS to be switched on before engine start; the device maintains nearly 12 volts output even with as little as 9 volts input, which keeps the electronic devices from resetting during engine start. The 4-amp module is $295; the 8-amp version is $365.For more information, visit TCW Technologies’ web site. A related Product Minute video from our sister publication AvWeb can be seen here.
