Hello Hubert. How's the design of your model? I have already completed mine: If you want, I can send you PDF drawings of this prototype in 1:32 scale? Here is the link to my gallery: https://pwm.org.pl/viewtopic.php?f=13&t=93103&p=1057177#p1057177 Greetings Marcin

Hello Hubert, I would like to apologize to you for the trouble with the engine. Because it turned out that the prototype of the fifth P11 from the exhibition in Paris in 1934, however, had a Bristol Mercury engine installed! In the publications that are available, on which I relied, the engine type is incorrectly stated as GR Mistral. Even the official catalog of the PZL factory is misleading by stating information about two engines on this GR and Bristol aircraft. However, I managed to get to the American (intelligence) report from 1934 describing the planes at the exhibition in Paris. This report clearly identifies the P11 engine type as the Bristol Mercury VI. https://digital.library.unt.edu/ark:/67531/metadc65353/ In addition, we made a comparative analysis of the photo and it turns out that it is a Bristol engine and not a GR. You can see the characteristic of Bristoli split exhaust pipes. Another argument in favor of Bristol is the information board standing by the plane which shows (a bit indistinctly) the inscription "Mercury VI" Once again sorry for the inconvenience but this is last minute information. You can leave the engine from the kit as it is best. Unfortunately, as a result of the war, Poland irretrievably lost most of its archives, which were either stolen or destroyed. As a result, the history of our pre-war aviation is incomplete and until today aviation historians and enthusiasts discover new information about Polish aircraft. We've just discovered a new detail. Greetings Marcin

The engine design looks perfect.

Hello Hubert, I'm working on the prototype drawings. Here you have the most likely silhouette shape of this prototype. At the top, a machine, at the bottom, a prototype. As you can see, there are some important differences that need to be included in the model. For now I am working on the remaining drawings of this prototype. Greetings Marcin

I am glad that I can help. Thank you for the proposition to print the engine. I also go this way and design a 3D model of this engine, I haven't finished it yet, so far it looks like this: Good luck :-) Marcin

The plane shown in Paris was a prototype that tried to interest the French. But Romania got interested in him, so he was sold to Romania. It was a model for the PZL P11F aircraft, about fifty aircraft of this type with GR engine were made, which were used by Romanians. The aircraft was offered for sale or license with a Bristol or GR engine. However, at the exhibition in Paris, this prototype had a sink GR 9Krsd. The P11C series copies already had a Mercury engine.At the moment I am collecting materials about this aircraft, but in this photo, although it is of poor quality, you can see that the engine heads are shaped like GR and not Bristol:

Hello Hubert, congratulations on taking on the rather difficult task of converting the late P11c into the fifth P11 prototype. As I am preparing for the same task, I would like to draw your attention to a few things that made this plane different from serial planes. First of all, it had a different engine, it was not the Bristol Mercury but the Gnome Rhone 9Krds engine. For this reason, there was a different exhaust manifold, a slightly longer engine crankcase and a slightly different propeller cap. The undercarriage covers you made so beautifully should cover slightly different wheels, which were smaller in diameter and a little wider. This plane did not have a radio station, therefore there was no door for the radio station behind the pilot's cabin in the fuselage. There was also no internal structure to hold the radio within the hull. There were no radio antennas and no mounting elements for the fuselage, wings and fin. This plane did not have bomb launchers under the wings. It also had a slightly different aileron design than serial airplanes, and the horizontal tail had a different shape, it was more convergent. There were probably more differences, but the documentation for this prototype does not exist and there are also very few photos. Good luck with the further construction, best regards Marcin PS. These are my two 1/32 scale models PZL P6 1931 and PZL P11 the third prototype 1932. Both are made from scratch.
