"Our resin cowling, prop, and spinner completely replace the Hasegawa parts from the firewall forward. (You'll use the Hasegawa three-blade prop for the Bf 109C/D, however.)

The upper cowl sections are different for each of the versions (A, B-1, & C/D). The cooling air intakes at the front are identical (large, simple slots) on the Bf 109A and Bf 109B-1. On the C & D these simple slots were replaced by more sophisticated inlets as shown in the photos.

There are a variety of cooling air vents in the rear section of the upper cowling on all variants. The problem is, there are a BUNCH of variations visible in photos, so we've included all the vents that we've ever seen in photos of that version on our part for the version. It's much easier to fill in a vent you don't need than to cut one you do!

Our Bf 109A set includes the short stub exhausts normally seen on that version. Our Bf 109B-1 set includes the long stub exhausts and the Bf 109C/D set includes both the long stub exhausts installed when these variants left the factory, and the ejector exhausts similar to those on the Bf 109E. Some Bf 109Ds, and possible some Cs, were fitted with these later exhausts in 1939 or 1940.

We were able to cast our props to minimize the sanding and reshaping so common with resin props. Our Bf 109A set includes the two-blade wooden Schwarz prop and spinner. Our Bf 109B-1 set includes a two-blade variable pitch prop and spinner, while our Bf 109C/D set includes a spinner for the Hasegawa kit's three-blade prop.

While we're on the subject of spinners, when you check photos of the early 109s you'll clearly see the spinners are smaller than the front of the cowling, which we've duplicated on out sets (that's why you don't use the Hasegawa three-blade prop spinner, just the prop itself).

From day one an important complaint about the Hasegawa Bf 109E kit has been the fact that the triangular quarter panel windows at the base of the windscreen are curved on the kit but flat in real life. We've fixed that problem and provide you a new clear cast windscreen with corrected quarter windows.

Of course, when the quarter windows were flattened, the "saddle" shaped section of fuselage directly in front of the windscreen no longer fits, so we provide a new part properly faired into the corrected windscreen.

Since the Bf 109A/B/C/D's were not originally fitted with radio masts, we also provide a clear-cast resin fixed rear canopy part without the slot for the radio mast. If you're building a bird that had a radio mast, simply use the Hasegawa part.

The early 109's wing was much different from the Bf 109E. Although there wasn't much difference on the wing tops except for panel lines, the wing bottom is a different story.

First, the early birds had a tiny oil cooler fairing under the wing instead of the Bf 109E's two huge oil cooler scoops with large aerodynamic fairings continuing onto the flaps. In addition, the first 109s lacked wing guns, and only later were small MG 15s added to the wings. In both cases there was no need for the large teardrop-shaped fairings for the ammo drums for the 20mm wing guns of the Bf 109E.

Our lower resin wing has the 20mm ammo drum blisters and oil coolers removed, and we give you new resin flap bottoms without the aerodynamic fairings as on the 109E. We also provide the small oil cooler fairing (which was in a different location on the Bf 109A than on the B/C/D).

Although Cutting Edge has a set of detailed wheel wells for the Hasegawa Bf 109E available as a separate set, we've included these same parts in all three of our early 109 sets. Some may prefer to retain the original Hasegawa wells, so we've left them in place on our resin wing. The Hasegawa wells can be removed to install the much more accurate and detailed wells included with these sets."
