AUTOMATIC IGNITION TIMING MODULE
• Automatic Ignition Timing: The BT-34EIS features an electronic ignition system that advances the ignition timing as the engine rpm increases. This ensures a delayed ignition timing at low rpm for easy starts and good low-end engine performance, and advanced timing at high rpm for good high-end power.
• The ignition module is waterproof.
• The ignition module runs on any 4.8V battery. The current consumption is approximately 188mAh.
• An optional Digital Tachometer (FJIG9920) is available to monitor rpm and ignition battery voltage.

SPARK PLUG
The recommended spark plug is a Champion RCJ-6Y or 7Y. To avoid improper operation or possible engine damage, do not use any other type of spark plugs. The plug gap should be 0.4mm to 0.6mm [0.016″ to 0.024″]. If the plug gap is incorrect, adjust it with a spark plug gapping tool, wash it with gasoline and allow it to dry completely before you reinstall the plug in the engine.
Note: If you want to check if the spark plug works, remove the spark plug from the engine, connect it to the coil and make sure the metallic threaded end of the spark plug touches the engine. Spin the propeller rapidly through top dead center and check for a spark. This procedure only works in a dark room as there is too much light outside to see the spark.

During our tests, our Fuji-Imvac BT-34EIS turned a Bolly 18″ x 12″ carbon prop at 7100 rpm which translates to roughly 30 lb of static thrust.The engine was new with 60 minutes of breaking in. The test conditions were: Temperature 59°F [15°C], humidity 20%, elevation at sea level. Performance may vary depending on atmospheric conditions.
