Fuel consumption, performance tuned – 1.6L/hr. (0.42 gal/hr.) Range is approx. 7.5 hours for 12 liters of fuel.  Inexpensive and reflex gliders, wooden propellers, heavy pilots, and un-tuned engines will burn considerably more.

Spark plug NGK BR10EG gap 0.9mm (0.035") Note: this is a resistor type spark plug that has a welded terminal which cannot be removed.  NO THREADLOCK IS REQUIRED.  Pilots may also use the B10EG/ES or the B9EG/ES.  Use of a non-resistor plug may increase the amount of noise created by the ignition that is picked up by a two-way radio.
