+1 ^^^ ...i own neuenergy/thunderpower/maxamps/truerc/elite/flightpower/zippy-h lipos and the only ones i wouldn't recommend are the maxamps....i would compare the zippy's to my neuenergy lipos.....i'm never going to buy name brand expensive lipos again.....these lipos are awesome and if you need more punch for insane speed runs get the zippy-r's....
