ZDZ 80 RV-J Super

The ZDZ Super 80 is a world class competition gas engine without equal! Awesome rotary valve performance! All new engine design with a larger rotary valve and new Hi-Flow porting technology. A great exhaust setup for your Super 80 installation is the JMB wraparound header and the new JMB TR 80 silencer. This engine and exhaust combination will swing the ZDZ or ZM 26x12 prop at 6600rpm and is extremely quiet. In most cases this combination will easily out perform 100cc twins in the same airframe! Fantastic calculated thrust of over 58lbs at sea level.
NOTE: As of Nov 2007 all ZDZ engines are supplied with bare aluminum cylinders.
