XRAY - Model racing cars

I understand that the raising the front upper link increases roll which seems to smooth out the steering , especially when driving on carpet, but what is the main handling effect when raising the rear upper link?

Also, would you run a longer or shorter link at the rear on a fast flowing carpet layout?

I struggled today with my car at EWS despite trying a few things to calm the car down, it was too tail happy in almost every run.

Skiddins

can you send us your set up?

Hi Skiddins,

Raising the rear link on the upper bulkheads will free the rear of the car up in the corners and should increase cornerspeed. It tends to give the feeling of the rear end floating around a little more rather than feeling locked down.

Are you racing at the International Memorial Cup at the EWS venue? If so come over for a chat! Ive had some good sucess with the 2012 car recently at the Ardent Virgin Winter Series, I finished 3rd behind Elliot Harper and Andy Moore. The car was amazing all weekend and so easy to drive! All 3 of my qualifying times were within 2 tenths of each other.

It was mega competative with the likes of Chris Grainger, Olly Jefferies, Kyle Branson, Jonny Aird, Chris Kerswel, Ben Cosgrove, Stefan Chodzynski, Matt White, Colin Price, James Hart and Ryan Edwards all racing in the 10.5t class.

I'll be posting my setup on here shortly.

Hope this helps,

I have raced at Ardent once and had a nightmare, I could race without crashing etc, but the track was tighter than anywhere I've raced before so I just couldn't carry any speed anywhere.

EWS is completely different, faster very open carpet layout, which again is not what I'm used to but each meeting there I try small changes and still go backwards.

Yes, I will be at the memorial cup.

This is what I ended up with at Newbury, here's my final, slate grey car in seventh, not the one with the green wing; (http://www.youtube.com/watch?v=omoFBD6-b54&feature=g-all-u&context=G2cca196FAAAAAAAACAA), which is more like Ardent. quite a few 180deg corners, but wider than Ardent, this was very good there;

I started with the above at EWS but it was too twitchy with too much oversteer which meant I had to be very carefull everywhere.
I made the rear camber link long for the last final... but forgot to tighten my pinion so never got to try it.

This is the event I was at on Sunday, car needed good steering but to be smooth;

make on rear 3.5* of toe in

car will be more stable and you will be able to feel the car more
try it
