Does anyone know how much this engine weighed? According to Mike Gretz's 'The SIG Chipmunk Story' article, G21-40 was used in the foam wing version of the Jim Van Loo's Super Chimpunk. This is the same version that Walter Umland kitted.

Do you know if G21-46 weighs the same or more?

RE: ST G21-40 (and 46) weight#4 source

The 46 is supposed to be 3/10ths of an Ounce heavier, but when I put my (flat-top piston) G21-40 on my scale, I got 9 Ounces even. My 46 was 9.3 Ounces. There was an earlier. "straight bypass" 40 and 46 for which the case looks like it should be lighter in weight - maybe that's why mine (all with flared bypass shapes) are heavier.
