One of our RC club members introduced us to this apparatus known as the "Vanessa CG Machine". I have seen and read about different versions of this set-up but hearing someone else rave about how well it worked I figured I would put one together and give it a try. It was very cheap and easy to put together, ($10.00 +/- and 45 minutes or so of your time), and I am very impressed with the results. The information about this rig can be found here :
