Rear wing sizes

[Jamesd]

Hi

Was not sure where was best to post this.

But I am currenlty building a rc car as a University project.

My job is to design and build a movable rear wing.

I have been doing some research into it and can not seem to find any equations for calculating the size of wing needed or the angles needed.

It is a 1/8th size with a nitro engine and 1/10th TC wheels and tyres.

I was planning on running a bar from the brake/throttle servo to the wing to change the angle but if u can think of another way this would also be useful.

Thanks in advance.

This has been done before in rallycross the car was called a Probe cant remember the manufacturer year was about 1993

there is a book on aerodynamics ..

this is it..... very good if you can get it...

Competition Car Aerodynamics: A Practical Handbook, Simon McBeath,

itll give you some good pointers anyway...i wish id have done my uni project on buggys rather than wasting loads of time on full cars with too many people pulling in different directions..

there is another book about vehicle suspension and the coefficient of friction...but a cant think what its called right now... ...

[Thargor]

just looked it up .. its from the same series.. competition car suspension by alan staniforth should give you some good ideas any way

Hi

Thanks for the advice.

I all ready own all the Compeition Car books. I got the new Areodynamics one last week.

They aint that helpful. With doing wing size.

I studied 1/10th TC bodies as part of my degree.

Remember you can't scale down air. Just be wary of that with whatever you design.
