We can see a voltage drop of approximately 1 V here. The current draw grows up to more than 30 A. This BEC works very wel. The rest voltage of 7,4 V provides very safe flying.
Adding some caps will cut the spikes a bit but won't have any useful effect here. Cosmetics only. So .. this is a BEC for use out of the box.
