To the Roo owners,

Did you do anything to the springs in the strut so that they will asorb the shock for landings. The way the Robart struts are now I dont believe that they could asorb any shock since the springs are so tight.

Thank you,

Hi David: Ill be facing that very question first of the week. I got a new front strut for my Roo. I will see what info I can find and post it for all to see. Bkf

David,

The Robart struts designed for the Roo work very well in stock form. However, if you want to soften them, shorten the spring. Just don't get too carried away. If they bottom out easily it defeats their purpose and will increase the stress on the airframe.

Hey David,

I felt the same way about the struts until the plane was finished. The composite Roo builds a little heavier than the earlier version. Once you have everything installed and the plane balanced, the struts don't seem as stiff. I would wait till then to make the decision to soften them up. I am thinking about shortening the coils in my mains, but the one I'm working on is one of the earlier kits.

Hi Gents

The only better way to absorb landing shock is with an oil damped shock. Someone has done one, but I can't find my info on it. I'll keep looking.

Ed: I think I have the site you look for. Give me a few minutes to wake up. Bkf

I would not change those springs at all. Any of the Robart struts that I have ever had are too soft, if anything. I know that you may feel that it is too stiff a spring when your plane is sitting in 1 G on your work bench, but in a landing gone awry, you want STIFF! A 19 pound Roo hitting the deck, even on a medium landing, is gonna compress and bottom out those struts. I've been looking for springs to make them stiffer, not wimpier.
