diffuser help streamline the air coming from under the car. its create like a suction. will kep the car stuck to the ground. at least thats what i think it does. i might be wrong

wan create suction ar

i think is better to do aerodynamic for decreasing air resistance when moving forward... however, i don't think aerodynamic producing down force will suitable for mini 4wd( speed car).

1. F1 need it for corner, because F1 using steering to turning corner... mini 4wd using track to turn, so why mini 4wd need downforce to corner??

2. if you study more, you will know aerodynamic might produce downforce, over done will slow down the F1 car on straight...do you think you wan't your mini 4wd to slowdown on straight?

3. racing is all about balance....

4. i actually let my car high let the air go into the bottom...also, the cover actually produce lifting force, in this case, i no need to cut a lot from my car... the lifting force help to reduce the weight...and i can maintain my car strengh...

If you talk about aerodynamic for mini 4wd, i think this is better and more useful for mini4wd... speed car only... jump car might be diff story...

i get what you mean .. if the car body is correct , it will generate lift making the car lighter and thus moving faster ?

moving faster or not might depend on motor and batteries....lighten the car by using this force may improve the motor efficiency...so use less batteries and no need to cut off a lot from the chassis...

when david talk about this idea last time, we bring several cover to test...

we stick the cover on the scale, start the small pc fan... 6~7g lifting force for avante cover....

it just a small experiment, it might consist error...so who have the scale at home, you can have a try...

easisest way to describe it , would be an aeroplane wing . when wind blows over it , you get your flying aeroplane. flip the wing upside down , you get downforce(and crashing plane. lol ) . lol

but i not understand why he put the 1 way gear like that... it's useless for 1 way gear if he place like that... maybe it got other usage...
