RE: Dumas sport 20 Pay N' Pak
The cowl on the 20Pakdiffers a little bit from the sport 40 size Atlas U-76 boat in that theres no cutouts for the exhaust stacks. I'm going to look around and see if I could find some exhaust stacks to put on the sides and I'm going to make a cutout up on top and fabricate a rearward facing scoop similar to the rear boat when it had the cowl on..
I have a 1/12 scale williams brother pilot bust that I'm going to use as a driver...
Here is the only pic I came across that shows the rear boat with the full cowl...
