While at Brickfest, Nathan shared his knowledge of radial engines with me. My
future radial designs will have an odd number of evenly spaced pistons/pumps.
I knew that one critical issue was that the piston shaft needs to point at the
axle of rotation when the piston is completely expanded and completely
contracted. After much use at Brickfest, my dual hex no longer did this.
I will be remodling it to try to make a tri-pump design to see if helps this
geometry.
