	Single Cylinder RCEXL A-01 System RCEXL combines the latest in ignition technology, Hi-tech manufacturing and rigid quality control. This makes RCEXL Ignition Systems among the best CDI ignitions on the market. RCEXL Ignition Systems are designed to produce the optimum performance from your engine. The low cost and ease of application bring the conversion of CDI flywheel magneto equipped petrol engines to electronic ignition within the reach of the average modeller. The system has also proved popular as a performance improving replacement for existing fixed timing electronic ignition systems on model engines. RCEXL Ignition Systems are also is being supplied, as original equipment, by a number of engine manufacturers. The RCEXL Electronic Ignition System defines new standards of performance and value. The RCEXL Model A-01 is a state of the art Ignition System designed specifically for use on petrol engine powered models. Standard features include microprocessor controlled automatic spark timing, fully screened plug lead with metal plug cap, Hall Effect Sensor with two alternative mounting brackets, disc magnet and timing angle degree wheel. A spare battery lead pigtail is supplied to facilitate the modeller making up a special switch harness. The control electronics and high voltage coil are housed in a single, ABS nickel plated case to minimise radio interference. Futaba connectors are fitted on the sensor and battery leads. A Futaba switch harness and a battery are also needed for operation POWER SOURCE 4.8 volt packs The RCEXL Ignition is rated for 4.8v to a max of 6v. A 4-cell 4.8v pack with a minimum of 1200 mAh is fine and creates a hot spark. The RCEXL Ignition runs most efficiently on 4-cell packs. We recommend that you always use a new 4.8v pack. 6 volt packs 5 cell packs at peak charge can be over 7 volts. Therefore, if your are going to use a 5 cell pack you must use a voltage regulator. The RCEXL Ignition runs more efficiently on 4 cell packs and will draw more much current at 6v, as well as operating at a higher temperature with no performance advantage. You also have a higher chance of RF interference. Do not use an old pack to power your ignition! WE STRONGLY RECOMMEND A 4 CELL Nicad or NiMh BATTERY OF AT LEAST 1200 mAh CAPACITY NEVER use the receiver battery as the power source for the ignition system

			Hall Sensor Bracket Typical Hall Sensor Bracket installation on a converted strimmer engine. Brackets are supplied to fit 30mm and 38mm diameter front bearing housings. Shown here drilled and tapped M3 to utilise the M3 fixing screws included with the system. A magnet carrier ring has been turned to match the housing diameter





	Timing Degree Wheel and Pointer The 180 degree wheel printed sheet has been glued onto a ply backing piece, which has been drilled to clear the prop driver stud. A piano wire pointer has been formed and temporarily attached to the cylinder fins with a bulldog clip. The ignition system is then connected to the spark plug and Hall sensor. A spark will be triggered as the magnet rear edge passes clear of the sensor.
