Battery comment:

"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 underrated in these packs they are one of my favorites." ---For Gensace user
