Here is where I will need everyone's help, and this is on a strategy to help make the air exit. I want a 3 to 1 ratio of air exit to air intake. SO far, this is what I have done. Cut out the bottom of the "radiator" box, and created a lip. However, this area is not enough for the air exit. I need more!!! DO you include the cut outs on the bottom of the fuselage as part of the air exit?
