Hi Joe,

I fly FAI and use Power Unlimited packs. My ones are from the very early batches.

So far I've had three 5S packs puff badly on me. One at 85 flights and the other two at close to 140 flights each.

In my opinion, they are great packs. Low IR, great voltage under load, light weight and excellent performance.

FYI, my packs were manufactured by Fully Max.

Cheers,
Jason.
