Well, somebody had a Tamiya TA-06 for sale here on rctech for a very good price, so I just bought it so I can prove to many of you how right you may be. 
It should be fairly easy to switch it between 4WD and RWD. I suppose I could just remove the rear dogbones to make it FWD, unless there is a quicker way.
I'm happy. I will soon have something to tinker around with.

I would really like to try running a carpet track. But just can't seem to get there without taking off work. Schedule just doesn't mix.
It's possible that with the rising popularity of solid axle trucks, Yeti, Score trophy, Baja Rey, that a brand could take chance with a solid axle road car. Or even one could be locked away in a companies vault of unreleased vehicles.

Sedan bodies already have more downforce than 1/10 F1s - have you noticed that huge wing in the rear?
You are still talking about RWD as it was doing nothing but donuts - interesting, I have different experiences with RWD - only time I experienced something you're describing, was on wooden floor
You just need different driving style from AWD or FWD - throttle has larger part in handling than in other two, making car more sensitive.
Ofcourse RWD is going to have trouble putting power of 500W+ motor to ground, but if we are talking about 17,5 or 21,5T classes, there is no problems with driveability even for solid axle cars.
With independend suspension, RWD could be very close to AWD. With more efficient drive, they could even beat them in some conditions (carpet races). But for sure, it'd be fun to have one class for both FWD and RWD cars with full independent suspension, to compare how they perform. Problem is that no manufacturer tried to make even hobby-class RWD with full independent suspension.

1:10-scale touring cars definitely don't have more downforce than F1 cars at the same speed. (1:8-scale GT cars with doorstop-shaped bodies have more downforce than F1 cars, but I was under the impression we were talking about touring cars that actually look like real cars.) Sure, the wing on the back of a touring car generates downforce, but most of that downforce just counteracts the lift generated by the rear windshield. F1 cars have body shells sculpted to generate downforce instead of lift, and they have minimal parachute-effect since there's almost no open space under the body shell, so the front and rear wings on F1 cars add to the total downforce instead of counteracting lift from the body.

On tarmac I could slam full throttle anytime without spinning.. I was using old Corally racing tires or old, worn rally tires.1:10-scale touring cars definitely don't have more downforce than F1 cars at the same speed.

F1 r/c car wings are often multi-plane. And air doesn't scale down well. Holes much smaller than an inch, act more like walls than they do entrances to a biplane wing.
I would not be suprised if a touring car body made more downforce than a F1 setup.
This thread seems to be justifying a "slower, more scale" race class. Smaller motors, heavier weight, closer to scale tire compounds...

The world of RC onroad cars is basically:
- 4wd independent suspension touring cars, or
- 2wd solid read axle pan cars, F1 cards
....
Why the mismatch? Shouldn't there be more RC cars that are laid out similar to full size race cars?
....
Shouldn't there be a RWD touring car chassis? Wouldn't that be cool for USVTA? Power slide around the corners in your '71 Cuda?
....
Thoughts?

The mismatch exists in pan-cars/F1 because they are a development of slot car racing. And touring cars are simply developed from buggies (see Tamiya TA01).
That said, once carpet racing disappeared locally I bought an FGX F1 car. Fully independent pushrod suspension all around and RWD. This has been done before with less success, look up the Tamiya F201, it's 4wd and IFS/IRS all around.
Recently, I've come to realize that having the motor in the same position as the real car is the more scale thing. To that end my VTA body was a DeTomaso Pantera, because exactly how many muscle cars are mid-engine?!
Also I'm putting a Porsche 911 GT2 shell on a M06 for rear-engine sake!

I had never considered that pan cars might be an offshoot of slot cars. Are they really? Slot cars (even today) are frequently bevel drive, and not "sidewinder" like pan cars are.
I"m so deep in pipe dream territory though. I want "real brakes" and "realistic power fractions" and "realistic weights" and "realistic rubber compounds". It would be slow, there would be lots of sliding. And I suspect we'd see most tracks have multiple "decent" lines to drive.
