Most people will run a CAP(680 uF 16v) on the ESC and some even run one on the transponder. We have had a few local guys with LRP ESC's that have these issues. They even sent the transponders into AMB. They did send them back new AMBrc's.
However the problem is still there.
I have ran a Quantum in my 12th scale with 4 cell, w/no problem however.
