Subject: tailwheel cable attach points? I guess this has been done many different ways but, I have the tailassy per the print with the coil spring and swing arms. Instead of theskid/blade, added on a swiveling steerable tailwheel. Should the wheel be steered by cables attached to rudder cablesinside the fuse ( more cables to pierce the skin) , or are they hookedto a horn on the rudder itself? If so, wouldn't this put too muchtwisting force on the rudder wood structure? If from the fuse rudder cables, at what distance forward in thetail? need all your input. thanks, Walt________________________________________________________________________________

DO NOT connect the tail wheel steering to the rudder post. It was NOT designed to take the torsional stress.There are other ways, full swivel or swivel & lock for take off is good.Other ideas ???DG________________________________________________________________________________

Walt, I'm no expert, but I have a second set of cables going to the tailwheel. J-3 Cubs and others are attached to the rudder. I don't knowwhy ours aren't. I tseemed odd to me to have extra holes in the fabric. I did it according to plans and have the extra holes. I'd do itdifferent next time.Copinfo(at)ix.Netcom.ComTim CunninghamDes Moines, Iowa (515) 237-1510-----Original Message-----

Walt, I attached to the rudder cables as they came back just behind the pilot's seat, with just enough movement allowed to avoid interference. I also made my rudder stops using swaged sleeves on the rudder cable. They hit against the seat structure which may not be the best solution and may have to be modified after I see how they work in the real world.

Walt Evans....Walt, I neglected to say that the attach at the tailwheel is on horns that are a part of the full swivel tailwheel assbly. This is a small lightweight unit that I bought from a source in Calif. I used it before on another plane with no problems.Don Hicks ________________________________________________________________________________

This conversation begs for the introduction of the idea that a direct cablelinkage to the tail wheel horn leaves one open to loss of rudder control ifthe tail wheel should be damaged or jammed in some way. Including a springin the tail wheel link allows forcefully over-riding the spring to get atleast some rudder control. Having suffered a damaged tail wheel, I canassure you that rudder control takes on new meaning. Of course, it becomesanother one of those compromise things where you have to decide how strongthe springs should be to allow tail wheel authority and still be able toover-ride it.John WKerrville, Txjandd(at)maverickbbs.com -----Original Message-----________________________________________________________________________________

Most people connect the tailwheel steering cables to the rudder cables,swedging outside the plane after the rudder cables exit the fuselage.These cannot be connected direct, but must have a spring at the tailwheelsteering arm so the rudder and tailwheel can have some independentmovement.John Langston>DO NOT connect the tail wheel steering to the rudder post.

BHP recommended attaching the tailwheel steering cables to the rudder bar4 inches out from the pivot point.This info is on the supplemental plans sold by Orrin Hoopman.Greg Cardinal>>> walter evans 08/21 4:03 PM >>>I guess this has been done many different ways but, I have the tail assyper the print with the coil spring and swing arms.
