RE: Tuff Flight's 4D
To build the horizontal stabalizer control linkage will require most people to try something new. This part must be soldered together from three seperate pieces. And even though I've soldered before, I've never used silver solder. The instructions walk you through it. You will need some silver solder, a soldering gun, and some flux. I picked up all what I needed at "Mernard's", but any Home Improvement store should have what you need. You can see my "Hi-Tec" soldering jig using an empty "Altoid's" box and a sanding block.
