Mathematically, the connection points on the blade's direction are two axle holes, so the whole build is a right trapezoid: DC = 1, AD = 2, and AB = 1.5. AB is the cam piece. The diagonal BC is larger than 2 but is forced into a length of 2, which are 3 holes apart, in the bottom liftarm. It's even more confusing that this problem can be avoided easily through the use of thin liftarms 1x4 instead of 1x3. In that case, the angle between the cam piece and the blade's direction, which is angle D in the figure, will not be locked at 90 degrees.

I did some trials yesterday and found out a compact pentagon connection design that doesn't require any special connectors. It's not entirely legal but it is solid enough. The mathematical foundation for this design is a right triangle with an angle of 54 degrees at the base. I tried different numbers for the sides, and found out that when one leg is 1.5, the other leg is 2.065, which is close enough to an integer. Based on that, I built this pentagon with a side of 4 studs and a perpendicular distance to the center of 3.065 stud, and then use frictionless pins and axles to bridge the .065 decimals. I test built this design in real life and it worked. I'm gonna use this in a small scale Airbus H175 model I'm working on. It's also an alternative model of 42113. I intended to wait until there is a shrink a model contest is announced to talk about this, but apparently there isn't going to be anything like that in the near future.

Or maybe it's only gonna be replaced with a screw version, just like the C+ hub.- 5,513 replies
