i have a pair of 9000mah smc packs and they are by far weaker than my $22 turnigy lipos. heck, my $40 4s turnigy 20c pack has more power than both of the SMC's combined.
They say a good mechanic only needs 2 tools - WD40 & Duct tape. If it moves, and its not supposed to, duct tape. If it doesn't move, and its supposed to, WD40.
