Jargon Busting!

Ah, Jargon! Love it or hate it, there is a lot of it. Some is really important to know. For example, bits and pieces of information that relate to "trimming", that is, getting the best performance out of your model. Other terminology is more esoteric, and arguably, not necessary for you to enjoy the sport of Free Flight (and it is officially a "sport" in the UK). I'm not proposing to explain all of the jargon. Instead, I'll list a whole raft of it now. Later, I'll explain some of the important terms, or at least give you a link to more information. So, in no particular order, here's a list:

1. Lift
2. Drag
3. Best L/D
4. Min Sink
