Four wheel drive, Query gears Options

[StuBeeDoo]

Which works better - I'm not sure - I do know that 4wd is the faster way around MY rally track - I did blind tests with my son removing the drive belt in his Avant slot EvoX

It's horses for courses. I wasn't convinced of the benefit/necessity of a 4WD slot car, so the first couple I bought, I disabled the drive to the front. I haven't done any back-to-back RWD/4WD lap time comparisons on individual cars, but all my 4WDs are now 4WD and on my track (44mtrs) they are at least 2sec a lap quicker than any of my RWD cars.

So I agree with RSClio.

Hi John
I like a challenge and the Hawk 6 is small and powerful and can be tamed with an electronic controller and I am going to use Voki gears. I am already building a front wheel drive anglewinder mini clubman. It has 5/8ths wide sponge tyres and the rear wheels can revolve independently and the motor is a hawk with an Proslot Puppy Dog armamture.

It must be horses for courses.
I remember the best 4WD car I'd ever seen suddenly started going better than ever. On careful inspection the reason for the extra speed became obvious - the front pinion had come unsoldered so it had converted itself to RWD.
I think 4WD has the best chance of being competitive in relatively low grip situations - rather like it is in full size.

I just checked ratios of the Integrale.
Previous setup
Rear 9/27 with wheel dia 19.5 or 20,41 mm/rotation
Front 9/26 with wheel dia 16.8 or 18,260308 mm/rotation.
The reason for using so small tires in front is that the car has to deal with several jumps so i want to give the guide maximum vertical travel.
The car was tail happy.
I switched to 9/23 in front or 20,642087 mm/rotation.
At home it looks good,but will have to chek on cocoa at the club,next week.Will post results.
I will also try is 9/24 in front or 19,782 mm/rotation

Both my prorace ninco's have had the same all round

That'll teach me to make a genralisation we have a Ninco Colberg C4 that is geared taller at the front

I race a ninco pro race citroen and have the front spinning faster than the rear and it works much better to when I had it 50/50 split.

The front seems to pull it out the corners better and being 4wd still the braking is excellent.
Its still very competitive against rwd rally cars although the msc scooby's that have made an apperance at the club are way ahead now (and they are all running rwd setup)

So I've bitten the bullet and now run an msc RS200, rwd set-up with deeper guide and better tyres which is giving the scooby'sa run for the money.
