    Aluminum struts

    I'm looking for information (weight/supplier) and photos (specifically the fittings at each end)

    Is it so the cub crafters offers alum struts on a carbon cub? Please share the pros and cons

    Thanks, Butch

    It is so. They are light weight and work just fine.

    D&E is another source. Last I heard you can't buy CC struts and related parts separately. Has that changed?

    Here are some photos of the D&E setup:

    I know Jay at Javron is (or was) working on this. The struts are not so much the problem, its the attach stuff that is. He is working with an engineer to get this done. I anticipate he will have it, and the weights, soon if not already. I have not asked recently how that project was coming. You might give him a call...

    I got mine from Carlson Aircraft. I made my own ends out of square tubing. Total installed weight is 26 lbs. I weighed univairs struts a few years back and they were 39 lbs with the heavy duty forks installed. I doubt that the carlson struts would pass the compression loads of a 1750 gw cub, but they are fine for mine at 1320.

    Most of the guys here in Quebec have aluminium struts on there experimental Cub or SuperCub. We also use the strut material for float rigging. It is cheaper to buy than sealed struts, and you can make custom attach fitting easily.

    http://www.aeronefmontreal.com/index...mid=54&lang=en

    We have the choice between 3.125'' (.750'' fllat inside) (0.8063 lbs\foot) and 3.625'' (1'' flat inside) (0.9945 lbs\foot). They are lighter than metal sealed struts. Next project I'll be using 3.125'' for all 4 struts.

    You can step or push on those struts...

    I can have the compression and elongation number for those if interested.

    My exp 180hp Super Cub (2400lbs gross weight) has one big strut up front and one smaller one in the rear. Big one for float rigging.

    Thank you for the post. Do you know a current source for the aluminum strut material and fittings? The Aeronef link did not work.
