Yea, I'm trying to figure out the numbers for Skis down,, the logbook shows weighed with skis on, but the down ski W&B has the same weight and moment as the up ski W&B,, should the arm not move when the skis are down changing the weight and moment?
This set, has been flown on this Cub for 30 years, I recently started flying it and when I reviewed the old W&B I discovered the numbers did not seem to be correct. Documents for these seem to be difficult to source. The Cub is a 2K Cub.

Yes, when you extend the skis, they move aft, though not quite as much as the Fluidyne 2200s do. But, enough that it'll change the arm a bit....and in the aft direction.
When the skis are down (ski position, they are pretty close to centered on the axles, so I guess you could use that as the location of the skis for the ski position. Then, maybe retract the skis and measure how much forward that point moves.
Sorry, I no longer have the logs for the plane my set was mounted on. But, I do remember different CG for skis up and down.
