"Good battery for the 250 class heli. I run these in my Trex 250 with the stock power system. The Gens Ace packs perform well to 4:15 of hard flying. They fly just as good as my higher priced packs with a higher C rating. 40C is under rated in these packs they are one of my favorites."
Remarkable stacking technology enables single cell capacities of 800mAh.
High discharge rate and high reliability
Small in size and light in weight
GensAce batteries provide high quality, reliable power for 250 class heli,800mm Warbirds and E-flite Blade CP/CP Pro.
