apart from one set of the blades being put on back to front... forget about the visuals of the direction of rotation, the position of the root fitting and the blade gives the direction of rotation.
The CH 47 is a longitudinal intermeshed copter layout with overlapping rotor disks. The rotors synch like two gears over the center of the fuselage as it is cheaper than paying for a new helicopter every time you add a cyclic input. The front disk advances on the RHS of the helo, the rear disk advances on the LH side, so both sets of rotors crosses the fuselage from the left to the right side.
What side of the blades are seen? The Ch47 has the front disc set at a 9-degree forward cant angle, and the rear disc is set at 4 degrees. longitudinal control comes from altering the collectives at each of the rotors, not altering the disk TPP. So the highest point on the rear rotor disk is always at the rear of the helicopter., same for the front disk. variation of the disk from the offset comes from flap back, which is speed dependent. Roll comes from lateral cyclic input to the disks, and yaw comes from mixing the lateral cyclic between the rotors. That all means that the rear disc's highest point is always to the rear of the helo, so in the 2nd and 3rd image below the rotor blade root fitting is showing a rear rotor that is advancing on the right side of the helicopter, and that is wrong. The frame rate does have the direction of rotation reversing but it also changes partway through the video or appears to, which it shouldn't, where the Nr and the frame rate haven't altered.
Sticking with it being false.
