Cat sx front wheels spinning

[chatts#725]

Hi all, new to this forum and to rc cars, i have a cat sx with lipo and brushless 6.5t motor, the problem i have is that i seem to get much more drive to the front two wheels than the rear, i never realised that this was a problem until i drove another one yesterday, i found it much easier to get it to oversteer etc. I tried to adjust the slipper clutch suspecting this may be the problem but didnt get the results i expected. If anyone could shed some light on this for me, or is that just the way they are?????
