Default 4 Seater Sand Rail - UPDATE again.

This is my try on a 4 Seater Sand Rail. It is a Desert Storm Chassis from RC4WD which will be modified to meet my needs as I will not use the suggested Traxxas parts but other custom parts.

This is just early stage and there is not much done yet practically as I am still in the planning and finding out which existing parts may fit best before I start producing my on stuff.

Pictures show what parts definately will be used so far. I am trying to build it as close to the real thing as possible.

So the official 4 Seater Sand Rail Project is started
Comments are welcome...

Well, as I wanted to go with a scale V8 in the back there is not much available for the trans. First I planned to use a XR311 trans. It is small and looks great, but is weak I guess. So I am trying an Astute trans. It is compact, has a ball diff and variouse gear ration options and I can go back further with the output shafts. This is most problem cause the half shaft may hit the trailing arm in case they come out to far towards the front.

The powerplant is a Ford 427 1:12 scale (actually I think it is 1:10) die cast model. I got it from a German seller, but they are from US actually. Also a nice 426 Hemi engine in red available in the same size. They fit perfect to the 1/10. Unfortunately there are not more engines in this scale on the market. Mostly 1/6 or 1/4 but they are way too large.

Next stept is to make the front suspension working. Then I'll do the rear end.

as for the trans...I am pretty sure that also the HPI E-Firestorm trans will do a good job.

what size bearing in the rear trailing arms?

That is a killer looking chassis and very creative in the suspension mods!

Correction: The bearings are 1050x40mm

Got new Astute rear drive shafts. The fit perfect to the width from the Gearbox Joints to the swing arms! Rebuilt the Gear box with new parts and fitted a Tamiya M-Chassis tuned Motor. This motor has an about 1,5cm shorter housing, so it does not lug out of the gearbox.

Just a quick Mockup. This is final position as the gearbox will sit.

Are those trailing arms still available? I'm looking for something similar for my next project (mounting blocks, hinge pins included) having them made is too expensive and I even don't know whether I designed them right or wrong.

Do they have camber or are the left and right arms the same? Do you think a Traxxas drive shaft will fit?

Thanks,

Yes. Those trailing arms are still sold on ebay. Search for Kyosho Scorpion. They are not expensice. The mounting parts are difficult to find. But you could use everything that works. Left and right arms are same. The only thing is that they describe a circle when trailing, so the outside mounting shall be higher then the inner. I can take some pictures and measurement if you want. Traxxas I have no idear. I know what Tamiya part will fit.
