@GrandMoffSilvey Ive only seen that spot drilled as a weight reduction, the only reason that they'd fill it, in my inexperienced opinion, is to balance it. I've never heard of anyone actually filling those holes, Id have thought that sort of a job was irreversible.
@117zoomzoom at 7:35 you to see two places where the rotors have been drilled just below 2 out of the 3 apexes. Then, they were filled. Why only 2? How much of a cavity, if any, is in those filled holes. There is a center of gravity, rotational inertia, balancing concept I don't understand. I have looked for videos now how people balance 3 rotor engines without much success. All I see are eccentric shaft balances.
@GrandMoffSilvey er, the drilled or shaved holes in the ROTORS is a weight reduction. The filled in holes in the rotor HOUSINGS and SIDEPLATES is that; ordinarily as you can tell from the side plate, the intake ports are on the side, and air is fed though a manifold connected to the sideplates. This 20B had a peripheral port (you'll have research ports to recognize the significance of different port types), so the holes were closed up and a new peripheral intake was made above the exhaust port
Someone explain to me the reasoning behind this choice of cross drillings with filled holes in the rotors and I want to see how they balance this beast.

Awesome video disassembly. I wish it had subtitles in english to know what are they saying.
