At the link below is an estes engine data table.

http://ecow.engr.wisc.edu/cgi-bin/get/me/349/bower/estesmodelrocketenginespecchart.pdf

Does the max lift weight include the weight of the engine?

After many B & C engines I've purchased a few D engines am looking at what
to do for the rocket to house them.

thanks.

.....answering my own question......I've played with winrasp and I now think
the mass in the tables includes the engine.

Apologies for such a tardy reply, but I think the answer is right
there in the document: "Do not fly a rocket/engine combination whose
lift-off weight exceeds the recommended maximum lift-off weight."
