You'll have to study the video for the exact shape, but I encourage you not to be bound by the shape I made. You might find by happy accident a shape that might work better for you. Start with a basic triangle with the side dampers on two corners and attaching the tip of the triangle to the front posts of the car and shape the car catcher material around the cowl you are using.
I'm planning to build my very first open build car with an FM-A chassis (Red) just like yours and this really helps a lot.
Cool! I'm glad my videos are helpful! :) FM-A is probably one of the easiest to make an open class car with because of its weight distribution.
How/where did you cut the car catcher for your poly cowl?
