My green 3.6 stroke Spektra has arrived and today I had a good blast with it. I'm not going to go into a long drawn out tech review, I am gonna say this. It has taken Gaston a long time to finally produce this machine, after going back to the drawing board over and over again. So, what was his agenda? I think he thaught " I want to create the Rolls Royce of Rotary machines " Gaston you have succeeded, this machine is the King, it's an absolute delight to use .
