ULPower motor - UL260iSA assembled

Weight: 74.8Kg - Power: 107Hp - Price: on request

The UL260ISA is basically a UL260IS motor. A modified engine casing, oil pan and oil collection system, designed by our own ULPOWER team, and an additional inverted oil system allow ULPOWER engines to fly inverted.

This reverse lubrication system addresses potential greasing problems. The oil suction pipe in the oil pan is mounted with a hinge joint. When climbing or diving up to a 90° angle, the oil pump can suck oil from the sump without any problem.

The reversed oil valve can change the collection direction during climb or inverted flight, which means that the oil comes from the top of the engine crankcase (which is now the lowest point).

The large (but lightweight) “oil breather” prevents oil from leaking out of the engine. The fuel injection system (instead of the carburetor) prevents the engine from stalling or losing fuel during inverted flight. IMPORTANT NOTE: A fuel tank modification is required to prevent the engine from sucking in air.

Oil Capacity: The oil pan should be filled with 4 liters of oil (1.06 US gal)
