do you think we are that bothered about aero drag?

especially in off-road, have you ever been to a track and thought that you should take off you super 'bod flap' wing off the back of your car because you are not fast enough down the straight?

half the time we are not running our fastest motors because we can reach speeds too fast for the track.

Nope Chris, I’m fully aware that no one is worried about aero drag. I was just using it as an example to explain why making smaller components such as wishbones aerodynamic wouldn’t be worthwhile. That’s all, I’ll go back to lurking now.

Don't go back to lurking, I was not aiming that drag coment at you, just general opinion really.

you have added some interesting ideas and the topic became very interesting after you post(s)

BenG · #64 20-10-2006

yeah, dont lurk, post. If I stopped posting everytime I got slagged, I wouldnt be here

Divefire · #65 20-10-2006

Ok, yeah I shouldn’t read boards at 3am, really not conductive to communication. Thanks guys, just glad to help, as it were.

Here's what I'd like to see in a new 2wd.

- Rear Saddle-Pack cell Location. (Yokomo BX style)
- Motor near center of the car. (Yokomo BX style)
- Adjustable angle rear wing mounts.
- Belt drive to make it forgiving.
- Servo mounted low and close the front of the chassis with stearing arms above. (Losi JRXS style)
- 4 screws to remove the diff.

you will be pleased with the Aero2 then mate, accept the belt drive bit

Having raced TC`s for the las decade of so this has been a "tuning" feature and created no end of debates on the effects of aero dynamics on toy cars, now from the use of a minature wind tunnel and touring car body shells the shape of the body only creates downforce up to 12 mph

after this it is actually drag that does the rest as air gets up inside the body and flares the sides etc.

I know buggys are a different shape but the wing will act as a stabiliser in the air just as it does on a TC at high speed. Aerodynamics is like everything else in racing its a compromise!!

A guy that races at lawford buggy club is running a car similar to what you describe, might still be pics on there site.

There is a pic of that car on this site. It's my dads car that runs a CAT 3000 chassis and a fireblade front end.

Can i get your msn tyrc. Or can u add me at biker9599@aol.com *anyone can if they wish*

BenG · #72 25-01-2007

added you mate

As regards rear wheel steering - I drove a development RWS 1/8th buggy once produced by a local model shop. All was good until it slid up to a track marking rope.........

You just can't steer away from the rope! To get the front of the car to point away and back to the track you have to turn in to the rope, which doesn't work. And if you steer away from the rope with the back of the car, thr front end points straight back at the rope!

That idea was quickly shelved I believe.

I did make a 4WS CAT XLS years ago when it had the old style rear hub carriers that allowed you to alter the toe via a threaded rod. Lots of bellcranks and pivots later it did actually work - the rear steer was about 50% of the front. But just too heavy and fragile to be competitive.

Mxrider99 · #74 25-01-2007

thank you ty. i first saw you at trcz. but then you kinda dissapeared. few people wondered where you went lol.

roboliver · #75 03-02-2007

in the early 80s mugen had a 4ws car called the bulldog mosy of us that raced them locked the rear steer it was pretty much usless

BenG · #76 03-02-2007

The CADs have been created, I can tell you it does not feature rear wheel steering. Why change a formula that works so well? I think innovation should be through other items, and will be spending more time testing and setting it up, than trying to get the rear wheels to steer.

However, I tried a Lola shell on my tc tonight, it was the dogs, so at the minute I am open to suggestions.
