LT 40 to tail drager
 

How did you hook you'r tail wheel up to steer ?

RE: LT 40 to tail drager
 

Normally the tailwheel is connected to the rudder in some manner. I prefer to use [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXFV47&P=ML]Sullivan tailwheel assemblies[/link] as they isolate the tailwheel from the rudder by a spring. Look at the attached pictures and you can see how this is normally setup. If you have a plane that you can't connect the tailwheel to the rudder directly you will more than likely have to run a seperate pushrod from the rudder servo to the tailwheel.

Ken, I had to do the push rod thing, just wondering how every body else did it on their LT 40. My Fly Boy 50 is set up like the pics. Man I like that plane..

RE: LT 40 to tail drager
 

I used an extra servo and a reversing y with the rudder servo.

ken i make almost all my tale wheels like the one you have shown they are simple to make.and i can use a standard tale wheel assembly.they work perfect and save your servo.

Hi in mine I used 2 servos at the rear mounted them about 2inches back into fuselage then I used a seperate servo with y harness for the rear wheel steering , I always use a seperate servo for tail draggers less hassles I run an enya 50 in mine and it balanced out perfect

I just used a second pushrod for the tailwheel on that particular plane. On other planes I do it like RCKen illustrated.

Remember to move your main gear forward so the axles are a hair (1/4" +/-) ahead of the leading edge of the wing (with the model in "flight attitude").

Personally, I don't bother with steerable tail wheels anymore. Heck, I don't even bother with wheels most of the time. :) I recently built an LT 25 and just used an old control horn as a skid. Ground handling is a piece 'o cake and I saved all the weight of extra linkages and/or servos.

Of course, if you fly off a paved strip, a nylon control horn won't last long. In that case, I'd go with a simple music wire skid. I did one on a MoJo 60 and it's absolutely trouble free. Here are a few pics of how it went together.

This plane has seen over 9 gallons of fuel so far and it still works great. It's very light and anyone can do it.

Run an extra push rod from the other side of the existing rudder servo. Hook that up to a tail wheel that includes a tiller type steering assembly. The sullivan tail wheels dont' work on an LT-40 unless you modify rudder (or the way the tail weel connects to the rudder). Something like this works:

Here is how I did it:

I used the Dubro bracket that is like this . . .

I made a new wire that was long enough to extend through the fuselage and up to the rudder with a 90 degree bend into the rudder.
I had a plywood doubler on the bottom of the fuselage to mount the Dubro bracket.
Run a piece of brass tubing from the Dubro bracket to the rudder hinge line to support the tail wheel wire.

For the main wheels, I used plywood doublers and the main gear from a H9 Super Stick 60. It is held on with nylon wing hold down screws threaded directly into the plywood.

mount your elevator horn slightly to one side so the tail wheel wire will clear. Bend a piece of 1/16 (long enough to go thrugh the fuse and make the wheel attatchment) music wire 90 degrees with about 1 inch to glass to the bottom of the rudder. don't glue till last though. drill a hole through the fuse (1/16" is plenty) straight down from the rudder hinge line. place your tail wheel bracket to match that hole. run the bent music wire thru the hole. glass the bent 1" end to the bottom of the rudder. asemble / bend the wire and tail wheel to suit the directions in the whell bracket (longer music wire required) BE SURE TO USE SPRING WIRE or MUSIC WIRE..... don't ask how I know;);)
