Hi Phil
I think you go to Louth club ?
My B4 FT is set as follows
Plastic chassis
Silver springs all round
35 WT oil front no2 piston
30 WT oil rear no1 piston
wishbones level at front
driveshafts level rear
gearing 23/81 on Novak 7.5L
Lipo mounted towards the front ( foam pushing it forward )
I also run 30 degree castor blocks with one washer under the ballstud for the inner ink.
Trishbits brass blocks front and rear, lead under lipo.
I managed 4th in the B using the above setup with a bit of slipper advice from Mick Cragg ( Thanks Mick !

)
You`ll love the racing, just dont expect to do any good cos the standard there is incredible.
That should get you somewhere near
