Title: Question About P-40 Propeller Types Post by: kb466 on February 25, 2010, 02:22:55 AM I have some questions for the P-40 Warhawk/ Kittyhawk experts. It is my understanding from looking at pictures and from what I have been told in the past, that there were two variations of propellers used on P-40 Warhawks. It appears that the P-40E and early F’s and K’s used a prop with a narrow blade, while the later F’s, K’s, L’s, M’s and N’s used a prop with a wider blade. My question is—Can anyone provide some detailed information about these different props, particularly the wider-blade prop?—such as specs, details, measurements etc.? Does anyone know for sure when the changeover to the wider-blade props was made—which production runs, etc.? Are these P-40 props the same as were fitted to the Allison-powered P-51's and A-36's? Any and all help will be most appreciated. Thanks!

It is noticeable that the early Tomahawk props looked different at the tips than say, a later model P-40N. They were all Curtiss Electric though. Yes, the early Allison Mustangs used the Curtiss Electric prop. As to how and when they refined the shape of the blade, I have no facts...

My name is Derek Bradshaw (I live in the UK), and I am a newcomer to these forums. I am a model maker and have made model master patterns for various companies for over 25 years. One of the reasons Bill has asked for technical information/dimensions for the later P-40 wide chord 'paddle' blade propeller (Curtiss Wide blade Part No 89303-24W) is because I would like to make one in 1/32 scale as an after market accessory for the Hasegawa P-40 kit. If there are any experts out there, or anyone who may have any access or technical details for these type of propeller blades, then I would be very gratful for assistance with any information that could be provided to me. Best regards and thanks Derek Title: Re: Question About P-40 Propeller Types Post by: kb466 on April 16, 2010, 12:54:24 AM If you can help Derek, please do. Derek is the gentleman who is preparing the masters for the spectacular upcoming 1/32 scale P-40F/L Merlin-powered Warhawk conversion. If we can help him out with information on the wide-chord propeller, it will make it that much easier to build an accurate late Warhawk. He is also thinking of doing some diamond or block tread tires for late P-40's as well. If you have any information on those, I am sure he would love to hear from you. Thanks!

Best regards and thanks Derek Hi Derek, welcome aboard! It's been a long time since I talk to you, I used to be one of the editors on LSP. Really looking forward to your conversion, I saw it on the LSP message board. I will dig through the factory drawings that I have and see if there are any for the propellers, if they are, I will let you know.
