    I didn't know Armstrong-Whitworth were involved in this heliochopper business

            Loving the Buchon's new desert "camo". Now what we need is a P40 in 112 squadron markings for some potentially amazing air to air photo opportunities.

              Saturday 24th June

              Another Spitfire (+ Buchon) Saturday at Duxford. MH434 and the Buchon went off to Bicester for the weekend to take part in the Flywheel Festival being held there. Back Sunday. PV202 and N3200 were flying with Classic Wings and MV268 of Anglia Aircraft Restorations Ltd flew off to Sywell for the afternoon.

                Duxford Saturday 24th June:

                FL25-14

                Desert camouflage is rapidly becoming very effective at Duxford as drought conditions continue:



                'Black 8' is likely to get shot down a lot at Bicester this weekend:





                G-SPIT/MV268 was one of 4 Spitfires flying today:

                          Wonderful to see Gemima the Gemini back at Duxford, where she lived in the early 80s with Mike Russell. Looking good!

                          G-INFO suggests a change of ownership in progress?

                              Soooo nice to see a 357th machine return to hangar 2. Just a shame it's not MOOSE

                                As one can see, the restoration of "Frenesi" is on-par with the finest/most authentic to emerge from Midwest Aero Restorations (even more evident when you look in the cockpit or into the gear wells) - in the above photo, the armor plate/seat has not been installed yet. The restoration was completed back in January of this year - the latest restoration to emerge from that shop. The airframe itself originally was built as an F-6K, but has been restored as a generic/standard late-model P-51D. The paint scheme is that worn originally by a P-51D-5-NA, the first production variant of the 'D', and while the airframe lacks some details of those early production variants (obviously they can't fly it without the dorsal fin fillet), it has an N-9 reflector gunsight installed as those early versions did, rather than the later K-14 computing sight, and although it has the late-style instrument panel rather than the early D-5 instrument panel, the main flying instruments are outlined with a white stripe rather than yellow, as the early D/K's had (different to the mid and late production examples). If you look at the stenciling of the production block information on the side of the fuselage, you'll notice there is a curious historical typo that was copied directly from a period photograph of the original "Frenesi".

                                  Just wondering as to why they can't fly with out the dorsal fin fillet?

                                    Great to see 'Frensi' has arrived.

                                    Look forward to seeing her on the 9th of July!

                                    (And of course 'Berlin Express').

                                    And thanks as always John for the history on her rebuild.

                                    R4118,

                                    As you probably are aware, the P51D-5 was the first production D model, and like the B/C and earlier Allison powered P-51s, didn't have the dorsal fin fitted.

                                    As time went on and the D-5 was used in service/combat, it was found that at high speeds, the directional stability was poor, and the rudder forces lightened up with excessive yaw angles being obtained, along with rudder reversals occurring with the potential for an unintended flick roll, or at worse, possible structural failure of the tail plane.

                                    So in late 1944, a Technical Order (T.O.) was issued to fit a dorsal fin to all existing D-5 airframes, as well as existing B/Cs as well.

                                    (There was also a T.O. issued to strengthen the horizontal stabilizer as well).

                                    The fin fillet modification also included the fitting of what was called a 'Reverse Boost' or 'Anti-Balance' tab, as fitted on late Spitfire XIVs & XVIIIs with the larger chord rudder.

                                    It was designed to add extra force to rudder inputs, thereby stopping excessive rudder deflection and yaw angles at high speeds.

                                    I believe what John was saying is that the FAA would not approve a P-51D without this modification, given the potential issues without it.

                                    And I'm sure John can give some extra details on the dorsal fin design and the differences between the field kit installation, and the factory installed one.

                                    Cheers

                                    Paul

                                      My mentioning of it goes back to a discussion I read among Mustang operators, accurate or not, that the dorsal fin fillet on the P-51D/K is part the AD's/Airworthiness Directives, thus required by the FAA to fly. Also, evidently if it was simply listed as a T.O., as it is in the Limited Type Certificate for the P-51B/C, it wouldn't be required/it would be up to the owner. With the loss of side area in the low-back design of the P-51D/K, the yaw instability and resulting issues were supposedly exacerbated. The fillet corrects the yaw tendencies and according to NAA helped to strengthen the tail as well. (BTW, just such a discussion was briefly brought up when "Happy Jack's Go Buggy" was first unveiled, as it is painted to portray a D-5 as well.)

                                        Thankyou for the extensive reply! I don't know a whole lot about P51s so hadn't heard about this!
