Tech-Aero - Ignition Battery Eliminator Circuits for CDI ignitions ( IBEC) - includes opto kill switch amongst its great features...download the user manual here.....

 (remember this saves you both the cost of an additional ignition battery as well as a seperate opto kill switch) also means there is one less battery to charge and less weight in the airframe.

* Eliminates the need for a separate ignition battery and mechanical on/off switch.

* Compatible with the power requirements of single and multi-cylinder model CDI ignition modules via jumper selectable 5V, 5.3V, 6.1V and 6.6V voltage outputs.

* Enhanced flexibility and safety via transmitter control of CDI ignition power from a receiver auxiliary channel.

* Tech-Aero exclusive 4 stage filtering removes interference from CDI ignition noise in the wiring path to the receiver, permitting use with 2.4 GHz Spread Spectrum and 72 MHz FM radio receivers. *

Filter stages 1 & 2: An advanced 2^nd order common mode LC power lead filter.

Filter stage 3: Triple power filter capacitors form a low pass filter and enhance peak impulse current delivery to the CDI module.

Filter stage 4: An optical isolator circuit prevents any stray noise from feeding back into sensitive receiver electronics via the signal lead.

* A high precision, very low dropout power regulator design further assures power receiver bus isolation with superior performance during peak current demand.

* One IBEC model fits all: compatible with any battery technology commonly used for radio control use, with a usable input voltage range from 4.8V to 10V.

* Bright 5mm LED CDI power on/off indicator with mounting bezel.

* High reliability Surface Mount components reduce weight to only 17 grams and a size of 25 x 45mm.

* Heavy duty 22 gauge twisted wire power extensions.
