    You may well find this very interesting. It is a different aircraft but there are a lot of useful parallels there:

      As he hits and the tail hits first the pilot seems to pull back on the yoke hence the high attitude of the nose prior to the plane stalling and nosing.

      Good vid, ditch a B24 and then gets out and combs his hair...what a guy.

          All mid to late WWII fighters and bombers had a variable prop, it also would have been feathered, so that the blades would be slicing into the air so not to act as 'air-brake', even in a ditching scenario they would have feathered the prop if the engine was dead, if not, the effect you described, would cause the plane to 'stutter', also any tail up attitude without a feathered prop meant the aircraft would achieve a 'stall' quicker so managing the aircraft would be difficult.Heaviest point on any prop fighter is of course the engine, the nose up attitude would be totally negated the moment the tail hit the water-no more lift under the wings, the tail hitting the water acts as a brake causing the plane to loose lift, speed and therefore gravity takes over and the nose will plunge. The props will have screwing on the tips-not as much as belly-landing on land, less if the props are idling due to being feathered. The nose will dig in bringing the tail up, damaged no doubt. Good chance the pilot could well be knocked out or even killed, rear gunner could be killed as the tail impacted, especially as it is the weakest point of the aircraft.

          To feather the prop just dunk in hot water for a few seconds take out and twist carefully to a straight on position.

          You may be surprised Si, to hear that most single engine aeroplanes with a constant speed propeller unit, are in fact designed to go to a full fine setting when engine oil pressure is lost, and not to a coarse or full feather position as you suggest. That is a system usually built into multi-engine aeroplanes, the adverse yaw between an operating engine and a failed windmilling engine vastly affecting performance and limiting control of the aeroplane.

              This is all good stuff. Thanks to all for contributing their thoughts and suggestions to my 'problem'

              Special thanks to Richard for taking the trouble to post the movie....

              So how about this....The aircraft has come in parallel to the waves (these will be small anyway)...After the initial impact, the prop has stopped, but the aircraft has 'bounced' prior to settling in the water. That is the instance I am thinking of modelling.

              Or....As Joe points out, the engine could have taken a hit and stopped, and the pilot is trying to get down as best he can, almost dead stick.....It must have happened somewhere I suppose.

              Does any of this make some sort of aeronautic sense?

              Thanks again for the input....I feel I could now land an aircraft in the 'oggin with no probs.!!

                Then I stand corrected non that point, thanks for the info Joe.

                  Yeah, dead stick why not, just a suggestion, why have the aircraft in the water at all, get some clear rod and have the aircraft just above the waves, you could also have a stream of grey/white cotton wool streaming from it, that would indicate a coolant leak and it is leaking glycol.

                    Good suggestion Si, trouble is I know couldn't make the smoke anywhere near convincing enough for me to be happy with.....But just above the water could be a goer. I do like making splashes though!!!

                    Thinking time, and thanks again for your excellent idea.

                      I have nothing to add sorry Sir, so I shall just sit at the back of the class and watch and listen if that is ok...

                            You could do it in a stall. sort of dead in the air after it has just skipped off the water and is about to do the belly flop----

                              Sorry boys, I've been distracted just lately. Regarding modelling, my rule is usually 'Finish one build before starting another.'....

                              But I've well and truly blown it apart....

                              I'm doing three parallel builds...Two 1/144 U boats and the Devastator! Water everywhere.....

                              I hope to finish them all soon.

                              Thanks for your latest posts..Might gee me up a bit!
