Default Shaft vs Belt drive

What are the good and bad points about each?

more knowledgeable will step in im sure..

shaft drive has torque steer i believe.
belts have a smoother power band.
if i were racing, i would prefer a belt.
if i were drifting i would prefer a shaft.

I have both. The belt driven is good but it tends to wear out after a while. Versus the shaft driven I've had since 94 and I still don't have any issues with it. If I had a choice now and since I had experience with both I would definitely get the shaft driven hands down. Since I never had issues with it.

It depends on the type of car, track/surface, and intended use.
Generally:
- Belt is more efficient (less rotating mass)
- Shaft has a more direct feel (although i'll admit i'm not good enough to feel it)
- Shaft can get torque steer, depending on the situation
- Shaft stays cleaner

So, if your track racing with touring cars, belt is almost exclusive. If your racing a dusty carpark, shaft is worth a look as you won't be stripping your diffs as often.

This may just be me, but belt cars a pain in @$$ to work on. I'm sure that not all cars are as hard, but my TA05. I have to just about take it all apart just to replace a belt. I like my TA05, but man it's high maintenance.

Ive been racing a HPI pro4 for years wit few problems...
Recently i got a belt drive car, Have run it for one meeting and ive had to replace a belt...

For stock or 540 racing i think shaft is great, but hotter motors make a shaft drive car a little nervous because the are so direct. Good for throttle control though... If you run offroad you would probably be fine.

Great question really...... all the pro's and con's are indeed true.

The bigger question is who makes a current spec shaft car worth anything!!

Torque steer is much more noticeable as you go up in power. You can run shaft in VTA with the slower speeds and less torque shift from the can and you will enjoy the direct feel that the shaft allows. Belt drive cars are still frequent there just because the gear is all spilled over from TC racing and belt drive cars is what you get. I think it takes a pro or at least a very experienced driver to tell the benefits of the belt over the shaft. That or a huge amount of power.

i ran shaft in GT3 (silver can) at the last TCS. set TQ by being the only one to do 19 laps... set the fast lap in the main BUT drove "rather poorly" (edited for the kids) in the main.

ran belt in GT2 (boosted 17.5).

it all comes down to what motor you'll be running AND personal preference.

I see a bunch of vids on youtube of shaft cars doing speed runs in excess of 100mph. Didnt see any torque steer there.

Shaft drive quite often suffer failures after a hard hit, particularly indoors.

If you had to replace belt already you either crash a lot or have something set wrong.

Because the gearing required to go that fast will reduce torque.

Gear those cars for Mod track racing and then see what happens!

TS is only visible when you're on/off power. At speed the chassis is already at steady state speed so there is little to no TS.

I run a 9T brushless in a shaft drive TC and the TS is very noticeable under hard acceleration and off throttle.

I run a tc4 as a speed run car and I have no torque steer but I'm easy on the throttle, prob 300-500 ft before full throttle. I like the diff ratio of belt drive ( I believe they are higher ratio)cars better but I have shaft..
