Bigger problem now Gear ratio for 1/16 erevo

[806mastadon]

What are the gear ratios for best handling on the 1/16 erevo vxl. I currently have 45 spur and 23 pinion Help me out here. It constantly does wheelies and now I’ve put on a wheelie bar. And it made it better but idk. Help out here. I’m running two nimh in a series
I’m chewing spur gears up

If you want less wheelies, you want to reduce the torque. Choose a smaller pinion and/or larger spur for a higher gear ratio. Traxxas has pretty good documentation and it will give you some choices of pinions, check your manual.

Keep in mind a larger gear ratio, means more speed and but also more heat in the motor, so keep an eye on that.

You could also run a smaller (less volts) battery. It will be slower but will also cut down on the wheelies.

The third option is to use training mode. It cuts the power by 50%.

This statement is backwards. If he wants less wheelies, he's going to want to go with a taller, or higher gear ratio by going with a larger pinion and/or smaller spur.

So for example:
A 20t pinion and 50t spur would be a 20:50 (20÷50) = .400 or 40% ratio.
A 22t pinion with a 48t spur would be a 22:48, (22÷48) = .458 or 45.8% ratio (note - a higher ratio).

Keep in mind a larger gear ratio, means more speed and but also more heat in the motor, so keep an eye on that.

This is correct of course.

You could try adding a little pre-load to the rear, and removing a little in the front to shift a little weight forward. If the vehicle is transferring weight to the rear easily, you can also try a little heavier oil in the shocks. Stiffer springs in the rear might help as well.

There are a lot of factors here to take into consideration. If you are driving in grass, try a tire with less of a knobby type profile, and more like a tractor tire to give a little more "slip".

Where are your batteries mounted? Pics might help.

batteries are mounted on the side in side the chassis. I use black springs in the back and green in the front but it seem like the green springs are stouter. And I keep chewing through spur gears. And am apprehensive to put the alloy on until I get the plastic one figured out????

How does the pinion look? Over time it wears to a sharp point and changes the pitch.

 

[806mastadon]

It was fine. But idk where it is at the moment. Was a 23 tooth steel pinion. That had maybe 4 runs on it. But not full runs cause I’ve gone through so many spurs

I may have gotten mad and chunked the pinion somwhere in my back yard oops lol
The spur gear doesn’t look that bad but I can use it anymore

Now my transmission just started smoking I set it back up stock and now I really have something wrong. 45spur 32pinion. But it starts smoking within a minute

The nut and spring on the spur is your slipper clutch adjustment. If it's too loose, the clutch will slip and get hot enough to melt your transmission.

To set the gear mesh, put a piece of notebook paper between the gears and slide the motor to pinch the paper tight between the gears and tighten the motor screws.

Ok. Thank you

You are correct, I wasn't thinking right on that one. Obviously not paying attention.

Ok. Thank you

I tightened it all the way then went back a full turn

Make sure to get us a video of the motor going up in smoke, or your slipper clutch burning up

In other words, keep an eye on your motor temps, and make sure your slipper clutch is adjusted correctly, because those tires are going to affect those things. You will possibly need a smaller pinion.

Run a 48 tooth spur and a 37 tooth pinion, it's fast as hell, and no wheelies, (but I'm on brushed so no cogging)

Those are the original tires for the MERV. It's currently wearing 1/16 Slash wheels and tires.

I feel like the 14.4v provided from the Nimhs in series and a loose gear mesh would probably eat spurs for breakfast.

I currently run 23/55, with Proline Trencher 2.2 tires. It's an absolute monster on dirt, definitely gonna lose a drag race though.
But it handles like a dream, and my electronics stay relatively cool no matter what I'm doing.


And as far as overall handling, good handling takes some work honestly, but, I don't regret swapping all the bushings for bearings, and swapping all the hollow balls for steel ones, that alone made a noticeable improvement. As well as stiffer springs, heavier oil.
I found the stock springs to be way too
soft, and I like 60wt in the shocks, opposed to stock 40wt.

And then there's the front,rear, and possible center, differentials. There's a whole lot going on in these little cars, but I'll stop before I get off topic lol.
