Mike/Wagen ... Nope not pulling too many amps. I am running the 5S 20C 4,900 mAh packs on my Wind 110. I got a wattmeter and only pull about 70A WOT. After each flight I put back in no more than 3,500 mAh. Bloated after 10 cycles. The Turnigy are 30C 4S 2,500 in my Sebart SU29-30 ... pulls only 50A WOT. It bloated after 4 cycles. I only put back in about 2,000 mAh. That is why I say you guys are LUCKY! Most people using it here have bloating issues. Flight Power packs are pretty good now, the batch from about 2 years back is much better, no more bloating issues compared with the batch before that.
