Do I need to do a new weight and balance for skis?
Hey all. I bought some skis for my KFIV and plan on mounting them soon. Do I need to do a new W&B? They mount directly below the axles. They are Summit Aircraft skis. I figured I can just add the weight of the skis to the same arm distance as the gear. There is a small wheel at the aft tail of the ski but the weight is minimal. I do not have a ski on the tail wheel. Thoughts? Thanks.

I just added the weight to the gear positions n and reprinted another form to carry with.

If you want to be really anal about it, subtract the weight x arm (moment) of the gear you remove, then weigh and find the cg of the skiis, cables, etc. Add back in the weight x arm of the skiis. The arm can be easily figured by measuring the skii cg location relative to the gear axle location. All this can be done by calculation, no need to put the whole plane on scales.
