Tucked Back Somersault

This is a novelty trick that takes a well known dismount (the Back Somersault) and turns it into a catch. In the video below you can see the flyer hold a straight position and tuck just before the peak to start the somersault, but it is also possible with the three kicks (forwards backwards forwards) familiar from the basic dismount.

If you are looking for a straight back somersault, which is a much more standard flying trapeze trick, then you need to look under 'Layout'.
