Default Shaft or belt driven

What is preferred a belt driven or a shaft driven car. What is best for competitive racing?

Belts. No one makes a competitive shaft drive nitro onroad car anymore. The TC3 doesn't like modern horsepower and Kyosho finally settled on belts after trying both designs.

The current belt driven models have better chassis setups out of the box and are optimized for racetrack performance. There is lots of setup information available.
The Ofna CD3 Pro is shaft driven and can handle modern horsepower but takes a lot of work to arrive at the optimum chassis setup.

Forgot about the CD3.

Still, stick with the top belt drive cars. Mugen, Xray, Kyosho or Serpent and you will be fine.

The chassis is better balanced with a belt car. That would be next big break thru in on road racing is to design a car that is shaft driven but has the balance of a belt car. A shaft driven car is more effecient than belt because of belt friction.

I always heard ring & pinion gears bleed off power alot more than belts.

That may be true. but I don't see it being as bad as the friction of three belts

Bottom line is if you race competitive you will want a belt driven car for the above mentioned reasons

For parking lot bashing a shaft driven car is fine

Even better, shaft has less problems with dirt.
