These are the Yak-1 pieces for the scratchwarbirds Yak-1 model. The exhausts are mirrored so just print two. Any other basic airplane files will be on my page. ( like the motor mount )

For the nose cone. Make sure supports are on higher than 20 percent so the screw holes print nicely. I use a 2 layer wall with 3 top and bottom. Infill anywhere from 5 to 20 percent will work just fine.
