Good point, but the slices are only for visual aid, so each body can be visualized.
The point is that there are no webs or internal dividers. The bodies have been blended into one duct!
Somewhat like taking a look at valved engines through valveless glasses so to speak.
James D. last version of Lady Anne has two intakes, IMO Lady Anne makes much more sense as two blended bodies.
The thrust levels somewhat give it away also, going from near 2lbs. to over 4lbs.
I built two different FWE before this last caliber type engine, but at the smaller scales I tend to not do so well with them. If I would have faired better would be reporting on a liquid fueled Anne by now. When I find time I may give it a go with a tailpipe of 1.5" minimum diameter, propane is so fussy at 1.25" . At the moment, the back log of work is to an extreme.
