What are good ways to put ballast in a plane?
The best way (IMHO) is 1/2″ brass tubes at the CG in the wings. You pour lead plugs slightly smaller than the tube. When you need ballast, you slide it into the wing. Add balsa sticks to fill any extra space in the tube. Another way is to glue a piece of hook velcro inside the fuse (at the CG). Glue the loop velcro to the lead. Simply press the lead into the plane and your ready to go. It\Qs quick and works well. The velcro takes shear forces very well, even a severe crash will not cause the lead to break loose. For 2-meter and larger planes, don\Qt bother with less than eight ounces of lead. If you think you need less than that, you don’t need any at all.[1] Safety issues which need to be addressed when considering melting and casting lead: 1) The melting of lead should always be done outdoors, as outdoors is the only place considered to be a well ventilated area. Indoors, even with an exhaust fan, is _not_ a well ventilated area. 2) Be careful when it comes to choosing materials for
