Hmmm I dunno about that, it depends on the type of setup you use. I'm retro-fitting a tailwheel to my Tiger 2 and I plan on just running the steering springs off two control horns from the rudder..........observe: http://rtccom.net/~mattb/pics/tiger_tailwheel.jpg

This is a C.B. Tatone tailwheel assembly, with a DuBro wheel. It actually comes with a control horn to attach to the rudder, but it's black (the rudder will be white here), and quite bulky. I plan on mounting two control horns, and secure the end that would normally have the backplate on it with the parts of the original backplate that are threaded. This will allow me to run the steering springs from the outside hole of each control horn to the steering arm mounted to the tailwheel bracket. I like the leaf-spring setup of this assembly, and the scale-like spring steering, plus it all keeps stress off the rudder. Only real problem presented by the retro-fit was getting at the other side of the bottom fuselage planking, hence the two cutouts you see in the pic. A bit of balsa and filler will take care of this later.

I fit a new tailwheel assembly to my Cub using the more standard plastic bracket setup. The wire the wheel mounts to is bent at 90*, above the bracket, so it sticks out to the side. I ran a small length of control rod from this to the control horn on the rudder, for steering. The way I have it set up doesn't give quite as much travel as I like, but it's good enough for controlling the plane on takeoff and landing. Taxiing is a problem (can't turn left very sharply) but I think this has to do with the bracket not being mounted correctly (the bottom of the fuse where the bracket mounts is too rough to mount the assembly directly......had to mount it to a hardwood block and epoxy the block onto the fuselage, and it seems to be at a bit of an angle now............)
