Hi DS Motorsport,

Your CAD images are great. Where did you get the dimensions or drawings to model the chassis/tank/radio plate assembly?

To DS Motorsport..

Congratulations because of your CAD images. Really fantastic!

..looking at your images I've noticed that.... I can't see where the receiver is mounted on your car.... ??

I see the LowProfile servos, the aluminium antenna support but.. where is the receiver?

Thanks

Thanks man.
Dimensions is all measuring with a set of verniers. Lot of work and quite hard to get everything accurate. Currently i'm am looking at getting some parts laserscanned/3d scanned to make sure at least the chassis is 100% accurate. Because I also want to make a custom front and rearend.

This week I will start on the rear end, it will be a combination of the recent 1/10 cars (Shepherd, 733, Capricorn) and the modern EP cars.

Thanks for the compliment.
The receiver isn't mounted yet because i'm waiting on a new housing and need to buy some double sided tape.
I will simply mount the receiver to the throttle servo by using double sided tape.

DS,

Fantastic car. Very interesting approach to the RC engineering state of the art.
Are you thinking about a CSO carbon fiber main chassis ? It's worth 60 grams or so...

I don't like the idea of a carbon chassis. It removes weight from the worst possible place: the absolute lowest position of the car. This will raise the CoG, so I think a carbon chassis will actually hurt performance instead of enhancing it.
If you want to start removing weight from a racing car work from top to bottom. For instance start by using aluminum screws for holding the wing instead of steal.
Also work from outside to inside.
The best investment in saving weight and improving performance is buying a set of aluminum pivot balls and Delrin nuts. Sharpens up the handling instantly.

Stick with the Xray lightweight ones, and the kit does come with steel pillow balls.

Xray Aluminum Pivot Balls will save up to 29 grams in comparison with the stock ones.

What about durability concerns ?
I've heard about been too fragile. Probably with Ti ones you'll save less weight but will have a tougher suspension for long mains...

The only durability concerns are at the lower front of the car. If thats a concern, just place the steel ones at the lower front, and the alu ones everywhere else.

You are right, they are more fragile than the stock. But they need such a hard impact that if you dont break them, you will break a lower arm or steering knuckle or both.

I had some pretty hard crashes and the one time I broke one was when I smashed my car full throttle (wasn't full speed) against concrete blocks.

If you are running the US style of tracks (wooden barriers or piping) I wouldn't run the aluminum ones, they are pretty fragile. The Ti ones are a lot tougher, if you get some quality ones, no 3racing crap. Or if you still make mistakes and have a couple of off's a day I wouldn't use them either.
I mainly race on tracks which have grass run off areas. On my first outing last year I hit the concrete pitwall because I missed my braking point and two alu pivotballs snapped right thru, also broke the Ti trackrod and bent the driveshaft.
