When we did the watt meter test, it was drawing 65-67A on the ground, fully charged. I'd imagine it could get slightly higher in flight.

I didn't think about the dual UBEC's but makes sense.

I've seen some prototype TT electric spinners and they are lighter than the standard ones. I agree 100% with the concerns they have with over tightening, I've been known to bend a few lightened backplates. But I've learned with the electrics not to be so heavy handed.
