Setup questions

[Smokey]

OK, got a couple setup questions for the seasoned vets. I am not a racer, but have noticed that my front diff unloads too quick, and she pushes hard into the corners.

I have an HB lightning....(I know, not the preferred choice around here), I am looking to change the diff lube that came with the buggy. I have never done this before and would like some recommendations for the weight for each diff.

I am not a racer, but, since getting the buggy I have not had to worry about breaking parts, just running. I am really getting into the 1/8 scale thing, now I want to get a little more performance.


Another question I have is clutchbell. I am running a 13 tooth CB powered by a C4. I am not utilizing all the power of the C4 since it never gets a chance to wind out. Would it be better to change the spur gear or drop another tooth on the CB?

Try another tooth or two on the CB before you change up the spur.

Also, in regards to diff lube. I would go with 3k in front, 7k in the center and 1k in the rear. This should get you where you want to be. Just do the front first and see if thats what you want. You can always step up from there.

CB size

I can only find 13T CB....nothing lower. Any idea where I can get one?

I think they fill the HB's buggy with grease and not silicone. You fisrt want to check if you have sealed diffs. I am not sure on that model. Like Christian said 3k-5k in the front works well and the higher vescosity you go the more to the longer it takes the diff to unload. So if you do find you diffs are filled with silicone its is most likely 3k so move up 1k to 4k. general rule of thumb 3-5k front, 7k middle, 1k rear

Ok, stupid question....how to tell the difference between grease and silicone? Color?

Assuming that there is either light silicone or grease in the front diff, will going to 4-5k help with the pushing? Or is there something else I need to look at.

silicone is liquid and runny where grease is a bunch of gooey stuff slapped in the gears.

on the second part all I have to say is experiment my friend thats what its all about. TRy 3k see what it does how it acts. Then try 4k and see if you notice any difference.
