Aerodynamics Tests

[1303R]

very interested too see what results you get, shame there aint much choise for beetle models, all seem to be standards and not very big. i been looking for a good 1303 shell for a while to make lill version of mine. anyways look forward to reading more

There is a link to the model. Shop around and you might be able to find it lower. Towerhobbies is nice and all, but a little higher than other places.

[beetle1303]

First update:

Order this

should be here next week

Since the cover has the wheel openings closed i can shape the fenders to the original. Along I will try and make a floorpan and the trans, engine, axles and wheels to fit under as in a real beetle.

I will post pics to follow.

For my body kit version i will use either thin pvc sheets so i can shape them, and epoxy to mount them and filler paste to perfect the final model

Im thinking of doing half stock and half modified, and seperate them with a pvc wall running across the centreline of the car.

also i will try to make the roof spoiler (lip) that goes above the rear window

I am very interested how much lift a beetle creates at high speed (say above 100 mph ++) and how much the roof (lip) spoiler can do to prevent that.

Couldn't you just drive-in a complete 1303 in there? That would be só cool!

Thanks,
Walter

dont know what i can do to help, but anything i can do just ask.
can tell you that the front splitter had more effect on the handerling than the rear wing but the rear wing improves the high speed stabilaty.

from what i have always been told is the lift on a beetle is directly related to air trapped in the fender areas. if you have releif holes or louvers in the back of the fenders it helps in stability of the car at higher speeds. seems logical since it is more directly the shape of a wing. but i may be wrong. just figured i would add what i have heard.

I think that is a very good point !
Now if he could just prove that as well in the windtunnel
