There might be by pass in the actuator, and not giving the retraction cycle enough power to bring the gear up. Of course as you said, jet inverted the gear easily retract, because gravity is helping. If you have a stethoscope, cheap at auto parts stores, to listen to the actuator. Or just go ahead and lube the actuator with O’ring oil.
While jet is inverted nose gear extends easily and operation is more consistent which is somehow weird and puzzling.
i have already dismantled/ cleaned and oiled all 3 actuators just in case.
Even if i get consistent movement on the ground i still cannot guarantee that it will work while airborne if air pressure will push the main doors open it would release the pressure on the doors switch valve....
