Default Tamiya vs. others

well, i'm wondering why Tamiya bodies are not ROAR legal...

is it cuz they have better downforce? or just better quality?
I really like Tamiya bodies...so realistic and high quality...

I mean sure you can use tamiya bodies in tamiya races, but the places where there are tamiya races are not even close to where i live. and yeah i know i can use a tamiya body cuz most clubs dont care anyway, but why they not roar legal?

Probably because of their wing sizes, which tend to be to scale, rather than to the regulations.

Also, Tamiya would need to submit a body for it to be approved - if they don't bother, then it wouldn't get on the list.

Sosidge's second responce is the main reason, they probably have never subitted a body for approval. Besides how many people would actually pay an extra $10-$20 just to run a body that looks more realistic??? I mean at that level it's all about preformance not realism.....

thats exactly what i was thinking...performance! a real car has its aerodynamics already proven by thousands of hours of research... so if you make it exactly to scale then the benefits of those long hours go to you....more downforce. Example: acura RSX... the real one is okay as far as areodymanics is involved, but Mugen spent hundreds of hours testing a body kit for the rsx which gave it a more aggresive setup... Tamiya now made the Mugen rsx body for 1:10 scale... so wouldn't it follow that tamiya mugen rsx is better than the HPI stock rsx?

Ummm... if you think a vacuum formed polycarbonate shell is going to have the same aerodynamic effect as a full scale bodykitted steel and fibreglass car, you really need to think again.

And wouldn't it follow that it's not legal for sanctioned competition? And even if it was, I'd still take a Yokomo Type A "Masami" Stratus over it any day. The physics of our cars are definitely not scale. A lot of the geometry of the "successful" cars today is drawn from experience and a lot of trial and error. Comparing full scale aero to 1/10 is apples and oranges. Now if you give a true aerodynamicist a proven body, ask him to modify it for a particular effect, wind tunnel it, test it, THEN I will believe it's better. But just scaling something down is not the answer.

.......unfortunately...... form follows function. Watching an RC race is like watching NASCAR. Sure, they're different makes and models, but they all LOOK the same, until you can see the headlight stickers.

its not as simple as just scaling it down. aeordynamics takes into consideration lots of other things (like weight distribution, drivetrain, etc). also consider that in an RC, you pretty much have a lot of hollow space between the body shell and the chassis. so there is definitly some airflow circulating within the RC shell - and that defenitly affects its handling (causing some lift). can you imagine if you were riding inside an RC? avoiding wind blown hair be a serious problem. a real car's interior is sealed to the outside world, so airflow is limited to the exterior of the car. hence it's design was developed with that as a given.

I would also think that with all the extra junk that Tamiya bodies have (all the little dimples and detail stuff) that they would have more drag than the smooth, purpose built bodies by Trinity, Yok (by Andy), Protoform, etc.

Also, from 20 feet, yes, they all look much alike - but from 200 feet, a lot of cars look similar as well. Ours are still purpose built (and tested) for 1/10th racing.

If I spend the time to build a Tamiya body, for sure it's going to sit on the shelf as a showpiece. Cost is a definite factor in that, since they are more expensive than other bodies. I can't think of any good reason to race one, they are so beautiful when you spend time to do one right.

Beautiful bodies. I have never seen these before. What cars are these bodies for? Were they discontinued?
