Oh man oh man oh man!!! Its good the cuts were not too deep. Look on the bright side now, with the scars you can tell them birds at the pub that you got it when you smashed your hand through a windscreen to protect yourself from 5 YOBs!!! How do you bungee her? I have my plane on the ground with the tow line attached and the bungee is held back with another cord. No tension on the plane and tension is taken up by the screw driver. My release mechanism is the trustly screw driver. I can launch this myself. Will put up a pic of it ... totally simple to make and super cheap. Cost me like 15 quid max.
