Hope its not serious,what is your esc cutoff set to? Might be worth checking across the balance lead with a voltmeter to see there is continuity between the cells. (i was thinking of putting the extra shocks on myself, you beat me to it!) It seems to work ok with the 8 shocks,just using 2 front,4 rear at the mo.Increased ride height without using the collars but needs softer springs or lighter oil. The Trenchers are pretty good too,plenty of grip even on loose,dry dirt.
