The main problem caused by the chassis rubbing is not the friction slowing the car down (carbon is quite slippery) but the fact that it rapidly transfers weight away from the tyres, which can cause...

Last Friday we ran the track anti-clockwise so grip was a bit down to begin with. However, even when the grip was up there was no issue with the bouncing :confused:

Probably shock related as you say. There is a small amount of wear on the spool outdrives but nothing causing binding. I swap the outdrives side to side occasionally to minimise wear but there's...

Not dumb ideas at all! But in practice I don't think the o-ring method will work very well on short travel shocks (maybe on a buggy). The tape method would also produce inconclusive results but could...

the older 3racing spur mount is a square pattern so most spurs eg. Xray don't fit; only 3 racing and a few other brands like RW and Kimbrough will. The new style 3 racing spurs have both hole...

Ok, so, Friday night racing on the gray rug @ Worcester. Grip is always a bit low to begin with here, as the carpet gets rolled up between meetings and it takes a while for the line to clear. Due to...

It annoys me how far out the battery is. On my 2k18 it's probably 4mm further inboard. No idea why they went for that big chunky motor mount when they could have simply mirrored the 2k18 one (and...

Ah I miss-read it. I bought a bag of 0.5mm rubber shims for that very purpose - they can help slightly on tracks with big kerbs; the car doesn't launch so violently off them. However I haven't used...

I will try 550cst, according to RC3 this will give a similar damping ratio to my other chassis which never had a problem on the same track (it did grip roll a lot - different issue)
