Posted: Thu Feb 18, 2010 5:53 pm Post subject: Landing Gear Shock Cords

I have the CH601HDS with tri-gear, and am getting ready to replace the shock

cords on the main gear.  The gear has always been very stiff; particularly

noticeable on a grass runway.  The kit came with 1080HD shock cords, which

is what I installed.  Has anyone tried the standard 1080, rather than the

1080HD?  If so, how did it work out?  Any other options?  No, I'm not going

to change to the spring landing gear.  Wish I had it, too much work to

change.



Thanks Folks,

Jim Weston

Hi Jim,

I've also got the 1080HD cords and the strut caps stick up about 3/8ths 

inch with me in the plane, 1/4 inch without.

My mains are responsive in a bumped landing to the tune of about 2 

inches max and seem easy to move during taxi.

My 601HDS has nylon guides in the top and bottom of the wings. Just 

changed out the main shock cords after 2 years

because I'd slightly damaged them during disassembly for paint.

I think the main spring gear on the XLs is much heavier than the strut 

type HD series and imposes adverse shock loads into

the fuselage.

Thanks Larry....That's interesting info.  I'm ashamed to admit it, but mine

are the original shock cords from 1998.  They are still working ok, but are

starting to look a bit frayed.  I guess that I'm not flying my plane enough.

Anyway, the gear has always been stiff.  Mine has never protruded out the

top of the wing.  I can tell from the scuff marks that the gear has traveled

as much as an inch, but no more.  I've even flown it from the somewhat rough

grass strip behind my house a few times.  The stiffness is why I'm

considering changing to standard 1080s.  I also have the nylon inserts.

Those shock cords seemed overdone when I originally installed them.  I'm

starting to wonder if they were mislabeled. 



Thanks...Jim Weston 601HDS
