Hello,

What is the difference between using a 190mm and 200mm body on a 1:10th electric sedan. Does the 190mm offer more drag or less drag for faster lap times ?

Thanks

Difference is 10mm.

200mm bodies give more drag as the air gets between the wheels and the body easier than on 190mm.

Plus they look terrible (200mm on a 190mm chassis).

Im still confusing...what happen if you put 200mm body on a 190mm chassis? any picture that I can see?

190 or 200 is the width of the car. So a 190 mm body will have the wheels fit nicely in the wheel openings of the body.

Stick a 200mm body on there and the wheel opennings now stick out 10mm pasted the wheels- thus allows a lot more air into the body creating drag.

oh ic, so 200mm body still fit on 190mm chassis but just far more ugly?

Just depends on what you like. Think street car with tiny 13 inch rims on it.

Utterly looks idoitic to me, but someone likes it.

get a ruler out. look at 1cm. your wheels will be in board half that distance on each side if you center the body on the chassis. to be more specific. you have 5mm of additional overhang over the tire/wheel.

Post 577 has pics of my cuda for USVTA.

Look at those pics and then normal 190mm bodies.

See how far inside the body my wheels are?

i see, wow it is ugly.....but it will be fine to get a 6mm wheel?

6mm or 9mm offset wheels are what you want, some of the HPI vintage and recent supercar bodies are 210mm in the rear so they look best with 9mm offset wheels in back.
