Page 9: Description Of Systems
Note: The UL260/UL350 engine comes standard with an integrated AC generator with external rectifier/regulator that can supply up to 30 Amps. The UL390/UL520 generator can supply up to 50 Amps. This should be sufficient to charge the battery while the standard engine is operating and other electrical aircraft systems are in use. -
Page 10: Cooling System
Operating Manual ULPOWER Cooling system All engines are air and oil cooled. Installing the ram air ducts that come with the engine, is mandatory. See installation manual for more info on this subject The installation of an oil cooler is mandatory as the oil is not only used to lubricate but also to cool the engine. -
