One of the XP-51G’s still survives and is under very long term rebuild by a Mr. Morgan in the US.

A very exciting project, I hope he ever finishes it.

Hello,

In fact, one Mustang (or possibly two) had previously flown with a 5 blade prop (lightweight prototypes XP-51G), and I have read somewhere (but unfortunately cannot remember where) that the prop fitted on the Whittington brothers’ was coming from this plane.

Anyway, 43-43335 was on of the two XP-51Gs protototypes that were both fitted with the Rolls Royce 14.SM engine, and the condition to have those engines was to give one the RAF one of the two prototype, fitted with a five blade prop. One was installed for 335’s fifth flight, and test pilot Bob Chilton reported that the plane was directionally unstable with that new propeller. Nevertheless, the plane made a total of 37 flight so equiped. The second plane, destined for the RAF, made a total of 54 flight before being delivered to the RAF , in February 1945 as FR410 (originally 43-43336). Information comes from the excellent book “Mustang Designer” by Ray Wagner.

A factory shot of 43-43335, from NAA archives:

Does anyone has picture of FR410/43-43336 with a 5 blade prop? I gave a quick look in my Mustang books, but could not find any (just one with a 4 blade prop).

Regarding the P-51Hs, they were all fitted with a 4 blade Aeroproduct Propeller, and one was destined for the RAF KN987), but it seems she never left the U.S.A.

😀 😀

Still, the ‘H’ model is interesting. Did they ever get a 5 blader originally?

Very true…..

I’m not American…

lol Yak 11 Fan !!

To me it gives the ’51H a more muscular powerful appearance.

Typical American, no taste at all…. 😮 😀 😀 😉 :diablo:

Thanks Crazymainer,

Just out of curiousity, does the 5 bladed prop alter the noise of the Mustang?

Turbo,

To me it sounded alittle higher whinning pitch but then i think all Mustangs are whinners 😀

Thanks for the link, Gnome.

I didn’t realise it was a Reno racer.

Hi Turbo,

Thats why Don put that type of prop on I really don’t think it help out much since the rest of the plane wasn’t slick up in any way shape or form.

Just another Question on the H I don’t recall the RAF flying H models if so when and were there weren’t alot of these things made and they spent most of their time bouncing from Active to Researve to Guard units.

Wasn’t it in the background of another shot under discussion here recently, with the 5 blader? Can’t remember where though! Someone did point it out…

Gnome,

Yes, thanks, and shots on the ‘MustangsMustangs’ site, but none with the five blade prop.

What is the history behind the Whittington P-51H ?
Looks like an interesting Mustang.

Any Mustang specialist know the answer to this one?

that’s a brainer – but I will check my records tonight

Mystery Prop.

LaurentB,

Spot on in 9 minutes – it is the Whittington P-51H.

This photo intrigues me. The aircraft is fitted with a five blade propeller.

This is not a quick exercise to squeeze a few extra miles per hour by fitting a propeller from a later Griffon Spitfire. These blades are opposite rotation to the Griffon Spitfire. The stencils, decals, Jablo white disc and Rotol wings all look to be period. This gives every appearance of being an ‘old’ propeller set. Old Dowty-Rotol wooden propellers have the habit of shrinking and become slack at the base adaptor.

It would be technically possible to change the spline on the engine output shaft to fit the five blade Griffon propeller hub but what of the pitch control system.

Any Mustang specialist know the answer to this one?

Yeah. What he said. 😀

P-51H 44-64415, AKA N49WB?
