just so everyone know this is for a remote control car haha, but id still like to know.
I understand that in a proper car it would require too much work to change all the gearing and stuff but in an rc car its easy.
so, would it make it faster ?
 
maybe if there is less loss through the transmission system then there would be more power to the rear wheels but not sure if you would even notice
 
well all transmission and gears and stuff iv taken out weighs over 300g, and when u think this is for a little rc car surely that shud take a huge load of the motor?
 
Will probably ruin the handling. Took all the gubbins out of my nitro car and it was an utter pig to control, well unless it was donuts you wanted to do.
 
R/C cars being the equivalent of 1000bhp monsters from the real world in terms of how much power and traction they have, you'll certainly slow down acceleration. It might corner faster, and would probably have a higher top speed, but that tends to be limited by gear ratios anyway.
 
oddly enough we just did this to a friends nitro powered RC car, the front right driveshaft kept popping out, the answer is no it just makes it almost impossible to control in anything other than a straight line :P
 
Did this to mine briefly, rear end just wanted to overtake the front all the time.
If the car is designed to be 4wd then its best to leave it that way :)
 
Not on an RC car, 4WD is usually much faster due to the limited run out of a RWD car to get traction, not fish tail and reach top speed. A RWD car with a low turn modified motor or decent brushless system will just donut whilst the 4WD will be gone. My losi would still sideways drift itself off the line as 4WD with a 9T in if nailing it.

If you are in a superstock race with 27-23T motor possibly even down to 19T or brushless equivalent then a RWD may be usable and competetive as overall speeds will be pretty low ~15-25mph on a track.

Over a long stretch maybe 200-300 yards a RWD RC car may out pace a 4WD top end due to transmission losses (if any really effect it in this scale) but in real world you will never get the opportunity to do this unless you are standing on a crane platform and can see the car.
 
Would be miles slower in the corner, as a normal rc car is 4wd. Removing the driveshafts will just ruin that and it will be cack as above.

If you look at the 1/12th scale cars where the motor is almost directly connected to the rear axle then they are massively fast, even with only 4 cells. To compensate they have fat rear tyres for grip and only really race on carpet where the grip is higher than tarmac (usually).
 
I did this with my old Tamiya Subaru. Front mounter mouted, belt driven to the rear. I had a supersports motor, 18t I think. Removed all the gubbins from the front and kept the belt to the rear (obv).

It was much much quicker and had a better turn in. in 4WD mode it tended to understeer. These were the Tamiya racing slick tyres, so donuts were just never an issue.

This is more due to the car setup and the poor quality of the cheap Tamiya kits.

With the proper cars understeer is not an issue due to everything being adjustable and the variety of differentials available for the front end. The motor will be mid rear mounted laterally in the car and the majority of cars are belt drive.

Up front you can run an standard diff which is adjustable, a one-way, a one way spool, or a spool with a standard diff in the rear.

The cars will run rubber slick tyres unless it is wet.

Or if you are on carpet in which case you will probably run slicks 99% of the time, but could use carpet dragons which are treaded. These are all available in several makes and compounds, tyre warmers and tyre softeners are used.

It gets as anal as racing a real car. Digital tyre warmers with individually programmable temperatures....
