What are these screw holes for ?????

[militarymaxx]

I'm going to feel stupid after someone tells me what goes in these holes. One pic is of the front hub and one of the rear (the two holes on the bottom, not the multiple upper suspension arm holes).

[Waste Land]

I've wondered the same thing. We can call them falling down dynamic holes. Less wind resistance coming down.

[HP Invent]

thats puzzling. Maybe the rear is used for some sort of brace. The front........hummmm, dunno....anyone have any bright ideas.

To mount rim scrappers when you are running in clay or mud!!!!!!LOL! It could be.
I wonder if they were a throw back to actual disc brakes on the wheels?

bill61 hit it on the head, they are for rim scrappers.

I know Fioroni makes these little devils & they arn't cheep either! Myself I use 2mm aluminum sheet & just cut them out myself, this also allows you to cut them to the width you need them as the Fioroni's don't quite reach the inner hub of all wheels.

I think they had in mind to be able to use these with all the different wheels on the market & went for a scrapper width that would work with almost every wheel!

The ones I build last about 6mo. of normal wear & tear & take about 30min. to make all 4. They work great if your running on loose sticky dirt, mud & clay!

When running in those types of conditions I'm sure you've noticed the wheels packing up, & if you have a large jump at the track with these conditions, well thats when you really notice the debris in the wheels. As that extra weight in each wheel (throws the ballance off too!) causes you to really have to ajust your driving lap after lap. This debris really effects the car while in the air, making it harder & harder to fly & land with any consistancy!

You can use pretty much any stiffer type material to fabricate a set of these & try then for yourself. I made my first set out of extra lexan & they wore out pretty quick, but it was enough for me to see how well they work!

You guys never cease to amaze me. I would have never guessed what they were for, but now that you've educated me, it couldn't be more obvious. It makes sense and I feel stupid......
Everytime I look at these buggies I'm amazed. They really did think of everything. Thanks again (Roadrash13 / bill61), for clearing this up.

[olds97_lss]

That is pretty damn cool. I would have never guessed. Anyone make mud flaps?

[Krautwagen]

Roadrash13, did you just use a flat piece? Or did you try to bend it at all so that it "dumps" the crud out of the wheel? I think I'm going to make a set of these

[bill61]

I never get to run in wet conditions (life in California is dry). I have seen these on the hubs since my first car, Kyosho Burns. At first I thought they were for some type of disc brake on each wheel, but the more I thought the more it made sense as being mud scrapper mounts.

[cbreaker]

It sounds very useful to me and I'm going to try to get some aluminum to make a set. Unlike SOME lucky bastards out in California, it's wet and yucky (and still damned cold) over here in New England.

I can imagine just the extra drag of a wheel full of mud can bring your power down.

Do you let them touch the rims? Probably not, I'm thinking.

[GilBeQuick]

Roadrash, any way you could take a pic of what you're talking about? I'd really like to see how that works.

[bill61]

I did get a couple of chances to run in the sand dunes out in the desert with my USA-1 Nitro, the sand sticks in the rims a little until you stop. That thing goes great in the sand, you can stop in the middle of a face then give it full throttle and watch it climb. Only managed to bury it once. I have a set of sand paddles for my buggy, can't wait to run it on the dunes.

[markallen]

Hate to be off topic but bill61 do you have two Nitro USA1's?I want to buy one.Email me or pm me please.

Man, I'm always scared to run in the sand...it just seems like it's asking for loads of trouble with everything.

I keep envisioning sand screwing up gears and sand getting into everything and ruining the drivetrain and getting into the engine if the filter accidentally falls off.

Is it as bad as I'm thinking?

[cbreaker]

Perhaps only if you drive like a nut =)
