Although is was 95 degrees here yesterday .....I have a question about ski installations on Cubs.
In an article I found on the net....it reads...
64. LANDING GEAR MOMENT REACTIONS.
In order to avoid excessive moment reactions on the landing gear and attachment structure, the ski pedestal height must not exceed 130 percent of the axle centerline height with the wheel and tire installed.
My question is....if you have bushwheels...and since that would increase the height of the centerline of the axle from the ground....would you be able to increase the axle centerline 30% above that with higher ski pedestals?
I'm thinking specifically about losing propeller clearance and AOA when changing from bushwheels to straight skis.
It seems like you would lose a lot of clearance when going to a straight ski like a Federal.....maybe some other kinds of wheel replacement skis have higher pedestal height?.
I'm sure other folks have thought about this before...and I was just curious in an academic sense how they worked around it.
This is an informative link about ski installations........
