- Finally, an explanation for why the paddle bladed P-47's climbed so
- much better. It wasn't just the addition of the prop, but the increase
- in engine power that made the difference. I've been mystified by this
- seeming anomoly for 20 years. It just didn't seem possible that the
- simple switch of props could make so substantial a performance
- difference. It didn't in other aircraft. Robert Johnson mentions
- outclimbing a Spitfire using the new prop. What he wasn't saying was
- that he was using all that extra power as well. Even though he wasn't
- in combat and just playing at the time, I don't doubt for a minute that
- he used every horse available to him so as not be be embarrassed during
- the encounter. Thanks for the info Joeseph.
