Nice shots, Steve.
Looks like a neat 1/2 A Proto Speed model in the first one. That event isn't even offered anymore. The Open flyers opted for Profile, which had been a Junior, or beginner event ay it's start! Too bad as the full body Proto ships are very nice to look at.
B Speed with side exhausts on pipes, WOW. That's old timey!
I competed at the Willow Grove Nats, very fun time and a great venue.
BTW; There is a Speed forum below this one; this one is for Racing.
