Serpent S411 - any good?

[Zoea]

Hi there

I purchased a couple of S411 rollers second hand, one of which has some upgrades. I'm running it with a VXX ESC and 8.5 motor (a good one).

It's not been very reliable - first run one of the belts came off, second run I think I lost a CVD / Axle pin so it's 3wd. Also it's way too fast for the really quite large tarmac surface I run it on. What size 48 pinion should I be using?

Are these good cars? Worth keeping? I think I paid around £140 for both rollers. My only local RC club is 1/10 TC so I was hoping to get some practise in and go try it out a few days, see if I'm able to keep up at all.

Should I sell the cars for something more mainstream or keep them? I also have a fair amount of spares.

thanks
