OK, had three flights with it today, this is the second flight, still working up on the packs, it looks like we are going to end up around 7 minutes, but its early days.

Landing at 33lb is not causing an issue, it was fairly calm, cool and a bit misty today, not ideal for EDF! Packs were not as warm as I'd like before we start...but summer is coming :-) I slowed it up a little more on the third flight and it was still showing no sign of a wing breaking away.
