I got my hands on an Evo for the first time yesterday and it's quite nice. The engine has internal kerostart and the valve for it is internal too. Only one fuel line going to the engine, one external soloid valve, the ECU (and GSU's) are smaller than a Jetcat. It looks really sweet. The Evo 90 is physically smaller than the P-70 but has more thrust. Check out the Evo 90.
