Sorry to read about your Angel . . are you saying that the battery FLOOR pulled out ?? Did the battery actually disconnect? What caused it to actually crash ?
The WIND 110E is awesome . . I flew my friends last weekend after the competition. It is fantastic. He flies with 10S 4900 packs, so just double up your Angel pack

He uses a Hyperion Z5025 (from memory) Outrunner. Amazing performance (see pic).
BUT . . don't forget the Miss Wind 50E coming soon . . put your Angel gear in that . . COOL
Cheers, JB
