Fenris, Welcome to the hobby. The circuit you highlight might have been a good option in 1995 but was outright vintage in 2005 (when the article was published). Technology has marched on and prices have dropped on off-the-shelf solutions. For a more reliable option (and at the same price point) consider getting a couple of Talon controllers. No intermediate ESC's will be required.
