I named it that because I think the robot mode looks like starscream from the transformer movies. To transform: activate 5 and slide volt all the way up, deactivate 5 and reset volt to middle. Activate 2 and very slowly (kill auto correct) slide volt up to top position, deactivate 2 and reset volt slider to middle. activate 1, slide volt to top, deactivate 1 and reset volt to middle. activate 4 and slide the volt slider in between the top and the second position markers. I cannot stress enough that you have to be slow when using activator 2. If your not slow, watercress will lose his balance and plummet backward unable to flip back over. Rate kindly and give me credit if you use this design as a base for something.
