For shaft driven car, there is less power lost compared with belt driven and it is more direct to your throttle control. However, front wheel always fight with rear one. If you can make use of this, you'll be benefit from it.

For belt driven car, you have a much smoother driving chain and let you have a smooth control over your car. For some extend, it has higher grid than shaft driven.

415 for sure has good design and it is fast too.

It is my 0.02

Nice explaining you got there bro?!! Shaft driven is much better that belt driven coz you have a less time in wear & tear of belts as compared to the shaft drive. When you're in a race and your belt snaps your race is over unlike to the shaft driven kit no belts to snap/broke. As far as I know tamiya 414m2 uses treated drive belts... durability tested and have a longer life span as compare to other belt that tamiya uses.

I've never seen that. If they are geared right, the front and rear should spin the same.

Neway, shaft driven car is more efficent then belt driven because there is very little friction between the gears compared to the belt's contact on the diff.

Not excatly;

At LOW speeds, shaft are more efficient. But at HIGH speeds, belts are the most efficient. So, theoretically, a belt car should be better on large open tracks, and a shaft car should be better on a tight technically track. But in the real world, there's not much of a difference. My HPI Pro2 (2 belt design), can easily follow and beat Yoke SD's, TC3's, evo3's....

From what I've read, a belt car tend to be easier to dirve, since it's more forgiving on trigger input....

I have to disagree on this.

During 4 years with belts, I've only replaced belts once... My belts never snaps and I almost dont maintain them...

Get a spare belt and give it a try... Or try sand it down to less width...

I sure be getting the Tbevo4 if tamiya has solve the drivetrain of the Tbevo3.
shaft drive is eazy to maintain compare to belt , if you just beware of accidents, ur shaft and bevel should last longer.

You can win with either car,belt or shaft.It's all up to you what do you want to race,In stock I like a shaft driven car and in mod I like a belt car,it's to each his own deal,but the 415 is a real nice car..
