I was ordering Turnigy lipos back in 2010 when not many people knew about HK. I agree that they have outlasted several more expensive packs. Also the same quoted specs as more expensive 'mainstream' packs have more punch and last longer each charge. As they are now 'commercialy available somebody should present them to Paul Worsely for BRCA approval? Good packs at half the price of some other brands. I used to really abuse Turnigy cells when running short course and they have never let me down
