The Bf-109F had a very unique flap setup when compared to the Emil version. The split flaps required extensive engineering. The outer portion was the traditional flap style, but the inboard flaps were different. The inboard flaps had two functions, one was to act as a flap but the other was as a cooling flap for the glycol radiators. The Friedrich had a unique style as well with a boundry layer being channeled through the upper portion of the inboard flap. This caused the F to have a ‘space’ between the two layers on the upper inboard flap. This is impossible to mold in plastic effectively.
Eduard has offered a complete photo etch version of this which works well but required a lot of bending. This new set offers the best of both worlds, resin and photo etch. This set comes in a blister pack with six pieces of grey resin with no blemishes. And one fret of photo etch with 14 pieces of brass to add. Most of these are stiffeners.
