Acrobatic aircraft typically do not have carburetors. The engines are fuel injected. The engines are designed to operate upside down by having an external oil sump that keeps the oil pump continuously submerged, too.
It depends on the aircraft, the speed and the maneuver that the plane is doing. If they are doing loops or rolls, no, centrifugal force will hold them in place. If the plane is 'flying' upside down, a maneuver that is possible in some aircraft, yes, gravity will cause them to fall.
Commander Aircraft is a type of plane. The plane can be traded through different services that trade planes. You can buy this plane at different auctions as well.
