Landing Gear with Springs or Solid link to save weight

[leshoman]

I have flown LE UL P-81 for about 60 hours and LE XL B-69 for about 160 hours with solid link in landing gear to save weight.  I have now changed both machines to spring links in landing gears.  It is the only way to go and i highly recommend the springs. Difference in Weight on LE UL was for each landing gear 6.3 oz. versus 18.1 oz with spring.  This equates to about 24 oz or 1-1/2 pounds of extra weight total.  Springs i used were from McMaster Carr, part number 9573K81 and cost about $ 8.00 each.  Springs make a major difference when not landing on smooth surfaces or working on short landings.

Great info Les. I have been thinking about this very subject, concerned about added weight. Guess i'll go ahead and add the springs. Not worried too much about weight now anyhow!

With added weight of engine may need heavier springs. the springs I have were pre-loaded 1/4" and with me in machine sets at about the 1/2" point or a little over.

Well , I just made a move from the 130lb engine to a 72lb one.
