KR> Aileron cable rigging with tricycle gear
Yeah, that's probably true. They also might have a bit more slop than regular cables. But since there are well known aircraft using them apparently quite successfully, these obviously aren't showstopper issues.

KR> Aileron cable rigging with tricycle gear
I don't understand why morse/teleflex/push-pull cables aren't more common in aircraft. I know Jabiru use them, and I've seen them in some other aicraft. I'm planning to use them on my KR. No doubt they're a bit heavier than regular cables, but by the time you include the fittings and brackets you don't need (e.g. every time a regular cable goes round a bend), and the shorter cable length, the weight difference probably is minimal. Not sure the cost would be significantly different either by the time you include all the brackets, pulleys, etc. for regular cables. It's not like they're unproven and it seems to me the time saving during build would be significant, which is why I don't understand why they're not more popular.

KR> Aileron cable rigging with tricycle gear
If you guys think about the KR design, the planes were to be as light, simple and inexpensive as possible. ?Also back when Ken and Stu drew up the plans, even boats were still using pulleys for steering. ?The push/pull cables were relatively new to the market for boats and would have been far heavier and more expensive than anything Ken would have used. ?That's not to say they aren't made lighter now and may be just the perfect thing for your plane. ?But that is why they aren't in the plans. -Jeff Scott Los Alamos, NM

I have always heard they have more friction than cables. One advantage in using these push-pull setups compared to cables is failure in one side could still let the other side work in the ailerons. The plane I am building uses them on all flight surfaces, but does use a cable on the rudder to get to the rear of the fuselage where the cable picks up.

I have an Aventura II and it uses the Morse cables throughout no bind, no slack and no tension on little brackets... very smooth operation jw Joe. E.

KR> Aileron cable rigging with tricycle gear
Has anyone used morse cables? (I think that is what they are called) like the ones used on boats? They bend easy and don't need pulleys. If you have a fold up wing, no need to even unhook them. -Original Message- From: KRnet [mailto:krnet-bounces at list.krnet.org] On Behalf Of jon kimmel Sent: Monday, March 18, 2013 8:03 AM To: KRnet Subject: KR> Aileron cable rigging with tricycle gear Just wondering if anyone has tried this idea...the diehl tricycle installation forces you to reroute the aileron cable...and most folks install a long bracket so they can install a pulley midway from front to rear spar outboard of the landing gear mount.
