I used the sullivan tailwheel rated for this models weight. i believe up to 10lbs, like a 40-60 size. I used a piece of ply epoxied to the plastic and foam, painted to match, attached with blind nuts supplied. I used JB weld to fix the pivot point on the rudder. that was the biggest pain but not too tough with the medium cure stuff.

I'm finally getting around to upgrading the tail wheel to a Sullivan. I have a couple of questions regarding your explanation.

1. When you attached the ply with epoxy did you rough up the plastic surface first? What thickness of ply did you use?

2. How do you use the blind nuts supplied? What are the steps to be able to use the supplied nuts and screws? I thought you somehow use small wood screws through the assembly and into the wood. If I can use the supplied screws and nuts it sounds sturdier.

3. When you talk about repairing the pivot point you mean the small plastic thing that attaches right to the rudder correct? Not the pivot point part where the small screw goes in right? That part on mine isn't broke, but the other thing did.

4. Lastly, the small wire that you bend up to attach to the rudder, did you glue it on the side of the rudder like some have suggested, or did you drill a hole into the bottom of the foam or plastic and epoxy or glue it inside the rudder? Then you simply cut off the existing stock wheel, right?

Also, what size Sullivan wheel did you buy to go with the 40-60 tail wheel assembly?

First, welcome to RCgroups.

Second, a video that shows how to install blind nuts is easier that explaining in text. The depth of the blind nut dictates the thickness of the plywood. The plywood should be thick enough so the blind nut does not protrude above the plywood.

Here you go on a video:

Here's a pic of mine. Has worked fine. Just screw it to plastic piece with some mid ca. Drill small hole in plastic rudder support and insert tiller spring. You'll need to cut off the original tail wheel of course.
