In tall paul's 3rd pic that looks like a dubro set up. If it is I have used two of them they work great. It comes with the wheel, bracket, springs, rudder control horn, wires, and all the connecting pieces. I have one on a 4star 120 and one on a great planes Extra 300s 60 size. I also have a pull pull on my 1/5 scale sig cub. I used the supplied parts for it, and it works great. I put it on my cub first and was worried but I prefer that now over the other. I deffinately do not like a tail wheel with out any control. I have seen them several times, and tried to taxi someone elses. They suck!
