Question about F1 racing chassis
Why do all the F1 class chassis use a "live axle" rear suspension?
I've been waiting to buy a proper F1 chassis with double wishbone suspension on the rear end. I have been waiting for around 10 years so far.
I think that live axle design on road cars Totally suck and I refuse to buy one.
From the point of view of someone who appreciates the technology in modern racing cars, I think it is COMPLETELY STUPID to use a live axle that mounts a heavy electric motor attached to the rear axle. Also the static camber, camber curves and roll centre are often compromised. Why do fans of F1 racing seem to think it is still ok to buy model cars with live axles. We are living in 2016, not 1976!

The solid axle is the king. Minimal maintenance, best handling and lightest. Just like a go kart. 3-racing sold a car with independent suspension. Was not really competitive, hence never caught on properly.

I would say the main reasons for this are that it works, and the rules allow it. For the amount of suspension travel these chassis normally see, the suspension that you get is enough to tune around most issues.
As far as the rules are concerned, if ROAR decided back in its infancy that all F1 chassis needed to have fully independent suspension, chassis like the F201 would've been more developed than the current solid axle F1 chassis. Even the first open wheel F1 chassis evolved from pan cars and now are more closely related than ever.
And scaling down modern F1 suspension and drivertrain to 1/10 scale to make it work to scale would be overly complex and probably expensive. I'm assuming here but to get moving parts that small and durable enough to take a couple of smacks to the wall would require some pretty exotic materials. Full scale F1 cars are not designed to bounce off walls and keep driving. Most things are replaced between sessions if theres even ANY sign of damage or wear. Imagine, say having to replace a wheel or a set of wheels because of an accident.
Your best bet for a true to scale F1 chassis is Tamiya's F201 (discontinued) but that's got 4WD, if you can live with that. There's also 3Racing's FGX (also discontinued). I think Kyosho way back in the day had a Pureten F1 scale chassis but again, super hard to find.
Personally, I love where F1 is now (both 1:1 and 1:10 scale!). You get multiple choices of bodies, different chassis to choose from, decals to race pretty much any team of your choice. I can live with slightly non-scale suspension.

Also 3racing FGX, also welcome to the back of the pack. That car you can build with almost 100% Exotek parts that are super quality, I own one, Awesome shelf queen.

No bumps on a carpet track. Don't hardly need a suspension at all. But if you lust after a slow, uncompetitive car, get one of the olde IFS F1's.

Here is your proper F1 car.
Has fully independent push-rod suspension, hydraulic disc brakes on all 4 wheels, even a semi-monocoque chassis to boot!

Thanks for all the comment so far.
Just to clarify, if I buy one of the "PROPER F1" racing cars such as Sakura F1, is it legal to race within scale F1 racing rules? I heard many years ago that for pan-car classes, that IRS was normally banned technology.
I am not sure how many championship winning cars have been built by 3 racing. I am fairly confident that if a company such as Serpent or X-ray built a F1 model with proper racing car suspension and the best quality components, then it would be very competitive. Quite simply it will allow better traction to transmit more power through the rear tires. Very important since its a 2WD car after all. I expect more predictable and balanced handling too.
Looking at how much touring car racers put into development of springs, shock tuning, and geometry improvements. We can't neglect the importance of geometry and suspension tuning. Back in year 2000 people were racing HPI RS4, and LOSI street weapon, Express, TA04 etc and thought they were competitive cars. Let's not have a closed mind to looking at improved racing technology.

Those cars were competitive with that generation of cars. Have you seen the 1/12th scale cars? They're the fastest thing in RC, faster than the 1/8th onroads. The less parts to a drive train the faster the car will be, lighter and more agile.
