”Ultra IBEC” Features
 Eliminates the need for a separate ignition battery and mechanical on/off switch.
 Compatible with the power requirements of single and twin cylinder model CDI ignition
modules via jumper selectable 5V, 5.3V, 6V and 6.6V voltage outputs.
 Enhanced flexibility and safety via transmitter controlled on/off control of CDI ignition
power from a spare receiver auxiliary channel.
 Tech-Aero exclusive 4 stage filtering blocks 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. *
o Filter stages 1 & 2: An advanced 2
nd
order common mode LC power lead filter.
o Filter stage 3: Three power filter capacitors combine to provide over twice the
capacity of others, enhancing peak impulse current delivery to the CDI module.
o 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 13V.
 Bright 3mm LED CDI power on/off indicator.
 High reliability Surface Mount components reduce weight to only 0.6 oz and size to 1” x
1 ¾”.
 Heavy duty 22 gauge twisted wire power extensions.

Summary

Ultra IBEC Features

Power Output Compatibility

Compatible with 5V, 5.3V, 6V, 6.6V output voltage requirements via jumper selection.

Remote On/Off Control

Enables transmitter-controlled on/off function for CDI ignition via a spare receiver auxiliary channel.

Ignition Noise Filtering

Four-stage filtering blocks CDI ignition noise for 2.4 GHz Spread Spectrum and 72 MHz FM receivers.

Universal Battery Compatibility

Works with most RC battery technologies, accepting 4.8V to 13V input.

Overview of Ultra IBEC

Purpose and Benefits

Eliminates need for separate ignition battery, reduces weight, ensures consistent voltage for CDI module.

Isolation and Noise Management

Safely isolates receiver/servos from ignition noise, but requires proper installation separation.

Connection and Wiring

Connects to receiver auxiliary channel; twisted wiring minimizes noise pickup and re-radiation.

Installing and Configuring the Ultra IBEC

Transmitter Configuration

Configure auxiliary channel travel, ATV, and sub trim; set failsafe for engine kill switch.

Current Draw Estimation

Estimates 100-120 mAh per spark plug for 10 min flight; monitor battery capacity.

Additional Usage Guidelines and Disclaimer

Mounting Recommendations

Mount securely using Velcro strap and padding; position LED for visibility.
