which is faster

[rc 4ever]

hi,

i would like to know what people think about a electric drive shaft car, and a belt driven one, can you tell me which one you think is faster top end and pull away and which one you find better to race, i would be very greatful for people's opinions.

thanks

At the risk of being poved instantly wrong I would say a belt drive car it usually the better choice,most cars with a shaft drive have quite a lot of gears at each end which would tend to be more in-efficent and maybe more maintainance.

I would say the one with the least amount of moving parts. I would think that the Losi XXS for belt and the Associated TC3for shaft would be the two with the least amount of drivetrain friction.

Ultimately the fastest car is the one with the best driver.

It really depends, shaft drive can be more reliable, especially mostly (TB02) having a sealed gear box. Belt drives get grit and dust inside the exposed gears. There seems to be less friction as there is noting to slip on the gears like a belt the drive is direct. But on a perfectly smooth, track rather than a carpark belt drive could be better.

You’re going to get a lot of opinions on this, I don’t have a definitive answer but here is some food for thought:

Tamiya just recently won the Reedy race of champions, all their driver were running the belt driven TRF 415, not the new EVO IV (shaft)…

The current world touring car champ is a belt driven 414…

The current world 4WD offroad champ is a belt driven buggy…

Most of the hot touring car manufacturers seem to be going over to shaft drive for its better drivetrain efficiency, The Tenth Technology cars were much quicker in a straight line than the competition when they arrived several years ago!

Spot on Shodog! - which is also why the Group C cars are ultimately faster than either belt or shaft drive cars (The original post didn't mention handling just speed!) because they have neither belt or shaft as the motor drives the back axles directly. The lack of friction in the drivetrain also gives them very long runtimes. I have had over 30mins runtime from a 3000pack with a stock group C.

After that any 2WD car will be faster in the dry than a 4WD and have longer runtimes.

Belts are definetly quieter than shafts but they stretch and need more frequent changes/maintenance than a shaft in my experience.

Thing is though, the difference between belt or driveshaft doesn't make a massive impact on top speed. You can get a shaft drive car to go much faster than a belt or vice versa if you alter your gearing/motor/bearings etc. Proven by the fact I've had a Thundershot go faster in a straight line than a TRF, difference being that the Thundershot lasted only 4 mins runtime against the TRF's 8mins

thanks evry1 for all of ur opinions i am very greatful and it has been a great help.

thanks again []
