I just found an old Fox 40 that is about 28 years old. Its so old I can't find a muffler for it so I had to modify one to fit it. The engine was broken in and flew once...straight up and then straight down. It has the compression of a new engine.

My questions are:

[ul][*] Is this engine worth using or can I get more money by selling it as an antique?[*] As an antique how much would it fetch you think?[*] How would this old 40 compare in power to a new comparable 40 in price? Were these old Fox engines dogs...the man at the hobby store said they were dogs and thats why Fox is not very popular in R/C today...
