I think for immaculately prepared surfaces, the LCG & SDW open gear design shouldn't be a problem. That's assuming no-one breaks anything, or parts company from washers/screws/bodyclips etc belonging to their car! LOL

For club racing on 'less than ideal' surfaces, I can see the potential for unwanted debris causing problems.

How about carpet? Does carpet fluff cause any problems?

Either way, fabricated lexan covers should help ease 'worriers' like me!!

I have another question for all you SD owners out there. Just completed a complete rebuild of my car, after doing the 90 degree servo turn. Had a problem that I experienced before:

The rear diff set-up is very free. And so is the front -- until I screw down the housing. If I leave the housing somewhat loose, things remain pretty free, but I think this could end up in a stripped gear. If I tighten the housing down (and I mean just to where there is some resistance to further tightening; not super-snug), it really starts to lock things up. I've sat and resat the housing (both sides), trying to get it as free as possible, and haven't had a lot of success.

* I've also tried between one and four shims between the spur gear and the bearing inside the housing. Going with 2 for now. *

The tightening appears to be most prominent once per revolution.

So here's my thinking - Given that the tightening is most prominent once per revolution, I may have knocked one or both bearings out of roundness. Alternatively, it could be the housing.

Your thoughts and/or experiences with the same would be appreciated!

PS -- if anyone is interested in seeing this 90 degree servo move, let me know and I will take a pic and post it.

Or it could be debris in one of the diff gears itself.

Make sure too that the input gear is fully seated on its shaft, and they can sometimes sit a little proud.

Yes i told someone this before and the pinion was not home all the way, he gave it a little tap and that drove it all the way on to the shaft

The Rayspeed springs are longer and are considered to be the tighest, tolerance wise, springs on the market.

i've raced a couple of times on carpet and no problem with the fuzz, all the outdoor racing is on parking lots, yes we blow them off, but we don't get everything, as you can still walk around and find screws, king pins, body pins, before and after the track is "prepped"

Hi,

the car has now around 120 runs trough it and I can say: Yes, it's a very stable. Only defect is an front rear suspension mount after a very bad high speed crash in the fastest corner of this track.



I lost a screw for the steering knuckle and hit the wall with full speed. And yes... this corner is fullspeed.

I had 2 races with the car, yet. First race was in modified... qualified 8th... ended 7th overall.
Second race was my normal class: 17T... qualified 4th and ended 2nd overall.

I tested yesterday on carpet again and the car did very well. Only problem now: The car as too much grip at corner entry and then it pushes through mid-corner and corner exit. It's quite easy to drive but not fast...
Any suggestions?

Thanks
Cheers
Chris

The track is very nice to drive but difficult as well... The chicane you can see on the left hand side is very tricky because there is something like a hollow... The car gets more speed at this point and you need a lot of courage to stay on the throttle and let it off very late...

Another nice track in the south of Germany... There was the race where I ran modified.

some of us are using the hard front axles off a mr4tc on our sd's so i would assume a standard axle and bone would fit, and i have tested with older style up rights, but only the front , not rear, don't know if they work or not, but is would guess yes.

You have to modify the old front hub carriers to fit. The old dog bones will work, but you have to use the rear bones on the front axles to fit.

Which is heavier, the LCG or the BD? Assume that the LCG would be fitted with a carbon propeller shaft.

thanks
