5 Cylinder Radial Engine Pneumatic Assembly Model Building Blocks Set MOC-39694-Build the Radial Engine Model Kit that Works

5 Cylinder Radial Engine Pneumatic Assembly Model Building Blocks Set MOC-39694  (872PCS) Features: Radial engines are primarily used in Aircraft, however some can be found in tanks, cars and generators as well. A key aspect of radial engines is the odd number of cylinders, (5, 7, 9 etc.) this has to do with the firing sequence of the cylinders themselves. Always firing every other cylinder, so for a 5 cylinder engine the sequence is as followed: 1 - 3 - 5 - 2 - 4 - 1 - 3 - etc.As it turns out there is no native pentagon shaped piece (at least that I know of) so some creativity was required on my part. Luckily I found some of those nice frames in my collection, those turned out to be perfect and thus the design process began.Initially I cheated a little bit, creating 5 identical 1 cylinder engines and sticking them together with a gear in the center. This worked, however I wasn't to happy yet as it wasn't a true radial engine. So I continued and come to a design that did work, well so
