I agree with all comments above.
Alan, I also take a step back in real 'bugger-all' wind but prior to the inevitable run, I also give a blast of air at 30-45 degrees, fanning as I stand stationary.............this gets air movement and gives additional aid to the wings inflation............................oh and it bloody works well!!!!
The motor is only used as an aid in nil wind conditions otherwise the minor snatch technique for me.
