| The most successful setups I've seen connect the tiller arm to the rudder with
springs. Keep in mind that a taildragger doesn't keep it's tail on the ground
too often and a free castering tail wheel is probably sufficient with a typical
low speed (read large) rudder. The rudder will be pretty effective with the
propwash (remember that big noisy fan up front? 8^)

| Jim,
The fin/rudder on this plane is a little on the small side, probably
to miniminze interference with the tow line. I did not opt for the
twin rudder setup because the external linkage looked dorky and flutter
prone(it probably would be fine, but I'm kind of a nervous Nellie).
Our field is a bit narrow and I would like to be able
to turn the plane around quickly and get off the field with the 100 ft.
towline attached. We do not drop the towline from the towplane when
landing.
I have seen the spring setup on a couple planes but need to look at it
more closely. None have showed up at the field this week.

| Well, since you have a huge capacity for weight carrying in this plane, why not
just put in a second servo on the rudder channel and dedicate it to the
tailwheel? That separates the control loss on failure due to rough feel bumps.
I'd go with a pull-pull setup in this case. Keep in mind that you can pretty
well fly with a stripped rudder servo anyway...

| 1613.4 | C.B. Tailwheel Excellent | ANGLIN::BEATTY | | Fri Jul 15 1994 15:59 | 11 |
| I have used the C.B. Associates tail wheel and it is excellent. The
springs that connect between the rudder and the wheel arm take up all
of the jolts a straight rudder to tail wheel imposes. The leaf spring
will help preserve the tail of your plane on the occasional rough
landing. I am running one on a 15+ pound plane now and ran one on a
smaller (Bud Nosen) Champ earlier. Do not waste your money with the
Robbe Unit. It breaks at the curve in the wheel support bracket.
My .02c worth.

| 1613.5 | C. B. Works Well | LEDS::WATT | | Mon Jul 18 1994 08:56 | 14 |
| I use the CB assembly on my UltraHots and it works well. THe secret is
the attachment to the rudder. You want the springs to be parallel to
the hinge line! I saw a good article somewhere several years ago that
showed how to make the tiller arms comming out of the rudder. You
drill a hole in the bottom and bend up an assembly out of 1/16 music
wire that glues in the hole. It has two arms that bend down from the
rudder that line up with the springs on the CB assembly. You solder
brass tubing onto these arms to give someting to attach the springs to.
Squash the tubing and drill a small hole for the springs. Sorry, no
picture. The idea is that the CB assembly takes all of the loads on
it's leaf springs. Coil springs connect it to the rudder.
