Disappointing! I didn't find the prog very informed, or informative, at all. I did miss the first 5 minutes but I heard no mention of the engines?
The most common were Warner Scarabs in the replicas, and they were replicas. The static Camel had a Clerget. However, the Camel was perhaps puffing castor oil - hard to say.
The Camel was always the best as far as we at Leisure Sport were concerned and easily got on top of the DR1. History is not easily changed of course. We certainly couldn't.
Combat speeds were 50-80 mph in the war
