audidriven,
It's definitely worth the trip.
It's one of the largest rc warbird event that I've ever attended.
It's a warbird and any scale plane built before 1962.
There are 150 pilots and about 500 planes. Minimum size is 80" wing span but most are 8' to 20' wide.
Here's the club's site and directions:
