|
|
I have decided to change up my rudder control cables on my IV. It currently has a 3/32" cable with the stock connecting ends...I'm switching over to turnbuckels. My question turns out to be which cable style is best to use? As I was looking at Spruce, they display differences in strandings... 7x7, 7x19 and a 1x19. Does anyone know what Kitfox uses? Are there advantages / disadvantages to moving to 1/8". Not sure here.
Thanks, Dan

Dan,
An educated guess.... and info.
7 x 19 for KF and general aircraft use (as control cables)
The numbers equate to strands and winds.
1x19 (1 cable made up of 19 single stranded winds) is the least flexible - generally used for standing rigging on a sailboat.... or other non-flex situations
7x7 (1 cable made up of 7 strand in each of 7 winds) can be used for non-flex situations (use only with large radius turning sheaves where turning is required)
7x19 (1 cable made up of 7 strand in each of 19 winds) can be used for flex situations such and control cables including (small sheaves and 180 degree are common)

I did the switch to stainless steel cables and turnbuckles, and I
used the 7x19 with swaged MS20667 fork-ends at the rudder horns, and
turnbuckles at the rudder ends. I'm not sure of advantages of going
to 1/8", but weight would be a disadvantage, along with stiffness,
but this doesn't seem like it would be a problem, given the pretty
straight shot from front to back in the plane. Mine have worked well
for over 200 hours so far. The plane came with the galvanized 7x19
cables.
