Motodelta D-bag Jump

Hello everyone!
I am Colin from Romania, and I recently got an opportunity to jump via D-bag from a motodelta trike. So, if anybody can help me with a jumping PROCEDURE, advice or links that would improve the safety , I would be very grateful! (I've jumped from tandem and baloon before, but it's my first time from motodelta (deltaplano))
Lots of thanx to everybody! Acro rulez!
