The early B-17 Flying Fortesses did not have engine cowl flaps, however, the Academy models of the early Fortresses did not properly model this feature.  If you look at photos of these early model aircraft, you will see a distinct opening just behind the cowl rings.  This was hidden by the cowl flaps that were added in later model Fortresses.  This resin upgrade supplies a more accurate engine mounting that rounds off the nose of the nacelle and also depicts the exposed carb inlet ducting at the 12 o’clock position.  This mod requires cutting off the front 0.27” of the plastic kit nacelle and replacing it with the resin piece.  The kit engine will fit into the recess of the resin part (clean up with a size B drill, 0.238” diameter to give a nice fit).

This would also be a good way to display open cowl flaps on later B-17 models – just add open flaps and actuators.

These Academy kits are the only game in town for an injection-molded early B-17 and they are very nicely molded and generally accurate, but they are pretty sparse on interior detail.  I also offer some upgrades based on the excellent new Airfix B-17 models – radio compartment details and main landing gear well details.  These work great with the early B-17s, so look for my other auctions.
