A break in prop for first discharges of a pack is by definition weak (I mean power and thrust).
That is definitely not the time to launch vertically.
Did you use 6X3 Sport, or 6.5X2.9 Pylon?
Still given that Amp draw, you would have had even less thrust with 5.4X4.5 E
Launch vertically after a few more flights.....not yet....not with a break in prop.
I don't recal having seen this reason for a crash yet. I think we need to add this to list of "Do Not"
Sorry your FJ became banged up.
Actually similar thing banged up my Stryker, but it was not due to cycling a pack.
8" prop, low KV, 3S, semi heavy build, and extra steep climbing after launch ended with same results as yours....minimal damage to nose.
