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.
James
