I fly these in my Gaui X7 3 blade and these are a great battery. Low IR, tight, strong, and at a great price.
Been running HRB 6s 5000 packs in my 700 electric helis for the past year... great batteries for a great price! What could be better?
Best value bar none. I can't tell a difference between these and my gens ace, and they stay like a brick with no puffing.
I have been very pleased with the performance and pricing.
I'm getting over 10 min flight time with the graphene battery my goblin loves hrb batterys
My son Tyler and I race boats. We've raced all over the country. We're always working on setups. The latest is for Limited Sport Hydro. We dropped the HRB 6000's in and shaved another half second off of Ty's heat time. Pretty excited about it. The boat is now over 10 seconds faster than the existing record.
