Are the Estes 24mm motors the same length as the 18mm ones? If not, what is the length difference.
Thanks,

The 18mm and c11 and d12 engines are all 2,75 inches long. The e9s are 3.75 inches long.
BTW, why are motors measured using two different measurment systems?

Having never seen the 'official' specs on how Estes (or anyone else) dimensions their product, I don't really know, but I suspect that they use one system.

When I went to school in the '60s and early'70s we were all taught to "think metric" because if the United States didn't convert to the metric system like the rest of the industrial world, by the magical year 2000 we would be a third world country!
On this page (https://nar.org/SandT/NARenglist.shtml) at the NAR website, motor dimensions are given in mm.Originally posted by Jimn

They still tell the kids in school that.
Although, in some cases it is easier to use metric than English. :kill:

Has anyone else noticed that motors are slightly wider at the nozzle end? It seems like whenever I put a motor in backwards (accidentally, of course) it is much tighter.

IMO, metric is easier in basically ALL cases. Still, that's a debate for another thread...
