Hey guys i need help understanding ground effect for my rc race car 6x6 build here are my questions. If I put edf fans to speed up the air underneath the car would that create downforce or does air need to get to a specific speed? If I put a fan on the underpan/floor of the truck would the fan suck it down? Would the air need to be squeezed in the undertray to speed it up? What would happen if you extracted all the air underneath with fans? How would you promote air to flow underneath the car by the front wing design?  Would the underpan/floor need to be angled facing up? FRONT WING 1 https://ibb. co/JtSx7Ps
FRONT WING 2 https://ibb. co/sWn4rs0
UNDERTRAY https://ibb. co/2dBNyZH
What is the best front wing for ground effect?
