I have the 1930/8 and the 1940/8 in different trucks. they both are absolutely awesome motors. In a full 5 minute race with 5s Lipo, the little 1930 was around 150 degrees(pretty warm outside, too). It is similar in size to the Feigao "s" motor, too, so this temp is a testament to the greater efficiency of the high end Lehner motors. I don't have much of a preference between the two, actually, but a heavy truck looking to maximize runtime and minimize temps should consider the 1940 motors the "cream of the crop" IMO.
