Can you be more specific? The ball cups and ends? or is it on the c-hub? My car has more play than when i built it, so i added some shims to reduce it again on the hubs in the front.

NolanP, what do you mean some cars are designed with play? I can't imagine someone doing that, as the play would make the car inconstant and unstable at higher speeds. Of course, i'm talking of an extreme case...

I'm not talking about a chub moving a full degree or an arm moving mm's. But the car has play in it when built and when you take it away it doesn't respond as well. The car needs some play.

No, actually a little play in the suspension parts is intentional in the design. NolanP is right about that. In operation the cars is under extreme loads which cause the parts to rub and bind when there isn't enough float in the fittings. That's what makes the car behave erratically.

little play=good
lot of play= bad

New parts for the Yokomo BD-7!

http://ets.redrc.net/2013/03/chassis...ntent=FaceBook


Ronald Volker has come to the island of Gran Canaria with some new parts on his Yokomo BD7. A new thinner top deck for more flex there is also new lower shock towers to compliment the new shorter shock absorbers. The new shocks have a shorter body and shorter shafts for a lower centre of gravity and more reactive feel to the car. There are no concrete plans to release these new parts as the team are just testing different options.

I just noticed, they are using the Aluminum Belt Tension Adjust Cams - yokomo parts IB-BTC

There looks to be a 2mm wheel spacer as well.

Ronald's car has had the aluminium cams on for a while I think, along with the aluminium anti roll bar links and rear drive shaft bones

What's the benefit of the aluminium cams? They can't be lighter than the plastic ones... must hold better the diff?

He is running the blue cams. I do think they are just more "trick" that the plastic ones. What is interesting is trying a thinner top deck. At a certain point there is too much twist in a chassis. I am trying to find the Mains from the ETS race anyone have a post yet?

After watching the videos, I'm interested to know if Yannic had the prototype parts fitted or not, his car definitely looked better than Ronald's.

I was wondering about that. Grip was really low in the mains, and I'm betting they would have been better off with the higher CG from the taller towers and shocks.

Yeah I know Reinhard was talking about there being almost like a sandstorm on the track. I have a feeling that the lowered shock towers are the reason that there was an issue for Volker
