Snappa,
Yes it's all brass tubing, music wire, brass sheet, bondo and silver solder.
Not shown was the servo mounted forward on a plywood plate.
The attached sketch gives you some idea of how it works. the original was done in full scale. So if you have the capability you can blow it up on the screen and get some idea of the sizes. Also the grid is 1/4 ".

Thanks for the photo, I have the tail wheel on a separate channel slaved to the retract channel and haven't set the limits yet. I'll set them when the tail wheel cover is installed.
