And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.
Radial engines needed to be warmed up - for much longer than we today appreciate, before they were given full power. It took a while to get the oil moving and hot. In-line liquid cooled engines such as the Rolls-Merlin, which became the gold standard didn't suffer from that problem, but they were more prone to failure from battle damage if they were hit in the coolant lines. It's like Mick Jagger said, "You can't always get what you want."
I saw one of these in a local museum. It's a rotary engine as opposed to a radial. The crank is fastened to the airframe and the propeller is attached to the engine itself. The engine and prop turn as one unit. As LL points out, lots of pros and cons. Video at the link: https://www.youtube.com/watch?v=wBSGNYaP56k
