ZX5 on grass?

[DanB4]

Hi All,

After winning a local race with a standard B4 I have again got the off-road bug.

My wallet is lighter but in return I now have a standard (not the RTR) ZX5 and a ZX5-FS on the way.

The track I run on is 100% grass so can anyone give me any tips to ensure it's/they're not a handful 1st time out? Which one should I run? The standard car or the FS?

Kinds of things I'm thinking of:

Should I use a front one way?
What springs front and rear and which manufacturers springs?
What tyres/inserts front/rear? Schumacher yellowsgreens? minipins or spikes?
What holes on the shock tower/wishbones?
What ride height?
What oil in shocks?
What to change if the grass is wet?

I am tempted to try the standard car first as I have LiPo's from my touring cars and the standard car takes stick/side by side packs whereas the FS needs saddle pack config si I'd need to resolder some NiMh packs.....

Thanks in advance!

Dan
