A "Starship" is the slingshot term for a forwards extended slingshot. As the wrist strain would be enormously high without a wrist brace, starships always have such a brace, and look a bit like the Enterprise NCC 1701 - hence the name.
Gary ("Flatband") recently started to play with full butterfly starship shooting, a new style he calls "Superfly". Now I have to try that too! Unfortunately arm braces are illegal in Germany.
So I used and older design of mine (the "Gloveshot"), because that concept avoids unwanted turning of the slingshot in the hand. Much needed for these not undangerous experiments! I simply sawed off the original "fork arms" and attached a 50 cm draw extension (20").
It works! Takes practice, and even weak bands are kind of hard on the muscles in my forarm. But hey, everything for power!
