Loosing my newsgroup feed

I got an eMail from Verizon this morning saying that they are dropping
their news server.

I'm not going to pay for a subscription to a newsgroup service for 2
groups so my question to the group is: what eMail list would you
recommend to replace this group?

I'm already on the Chuggers list but are there other ones worth being a
member of? I'm not building a plane but I find I learn a lot of tools
and techniques from the aircraft builders. Who knows maybe someday I'll
get to build something that flies.
