I have a Losi XX CR Kinwald Edition Buggy. I want to know what kind of gearing I would want for it. I do bashing, oval dirt track racing and climb some dirt mountains I have around my house. Right now I have a robinson steel 13 tooth pinion with a pitch of 24. What would go good with it if I want speed? and what would go good if I want tourque? Is there something in the middle that would be good overall? Also, would I want a steel spur gear or a plastic one?

There is no such thing as 24 pitch for 1/10th scale cars.

24 pitch would mean it had teeth MUCH larger than a 1/8 nitro buggy. They use 32 pitch.

MY mistake it has a pitch of 42 and I checked it

So it must be Kinwald pitch gears??? Those are special gears made by Losi and Trinity. They went over on the hobby as well as a lead balloon.

The only other gears available for 1/10th scale are 48 pitch (most common in 85 % of cars) and 64 pitch (used most often in on road pan cars and touring cars on carpet).

so like 48 pitch or the special ones?

hpiguy

If you want speed then reduce the teeth on the spur or increase the teeth on the pinion.

If you want torque, reduce the teeth on the pinion, or increase the teeth on the spur.

There is no set ratio to go by. Just experiment until you find the gearing that suits your use the best.

so like 23 teeth on the pinion? and how many on the spru gear would you suggest? I'm going to get a metal one. Maybe like 84?

hpiguy

You need to experiment.

Buy several gears, they are cheap if you get the plastic ones.

I can't recommend specific gears for your use. I don't have any idea how this car will be run, how hot it gets, etc.

Just follow the guidelines I listed above and you'll be OK.

I got a new pinion and a new spur gear. The pinion has 23 teeth and the spur has 85. Both have a pitch of 48. My buggy is pretty fast now but is still a little hard to handle. How would I fix that?

hpiguy

How do you mean "hard to handle".

You aren't giving ANY info that you can be helped with. The faster the buggy goes the harder it is to drive.

You need to TUNE the car for the surface you are driving on. This means adjusting the caster, camber, toe in, shock springs, shock oils, pistons, sway bars, tires, battery placement, etc.

You need to EXPERIMENT over and over until it handles right for you.

The FIRST thing you need to do is SLOW DOWN. Fast speeds don't mean good lap times. They mean BIG CRASHES.

It only means "BIG CRASHES" if you can't handle it at those speeds.

If you can handle your car then you should be going faster, practicing with higher speeds, harder tracks, different serfaces. You don't slow down until you crash, then you fix it and try again.

hpiguy

You don't know how to tune your car, or even buy gears.

That means you shouldn't be driving as fast as you are driving OBVIOSLY.

Try to help a kid and he bites you head off. If you are going to insult and argue with the very same people you ask advice from then expect to get yelled back at.

hpiguy

Can't even drive or TUNE the thing but wants to go faster. Go figure.

How the hell did I yell at you? You are the one insulting me in the first place. I asked you a question and you answered it I said thanks , and now your trying to bite me in the ass because I'm new to offroad and I don't know how to tune it yet. Sorry and thaks for the help.

My gears on my kinwald is 48 tooth spur and 22 tooth pinion and it tops end is at 29.57mph and with a brushless motor it tops end in 69.82 mph

that's cool, why do you have a 48 tooth spur? for more top end? what motor do you have in it other than the brushless?
