1.2kg of fireworks on a FY-450 4S quadcopter

1.2kg of fireworks seems like a lot
take off weight of the FY-450 is usually 1.1kg
indoor test flight went well with quite some lift to spare
full armament
everything mounted
final take off weight is 1.9kg
fuse cord beneath paper cover
take off and immediate crash
fireworks went off after crash
on-board view

immediately after takeoff the quad crashes despite being at full throttle. set off by either turbulences or too aggressive remote input, the additional weight causes the PID feedback loop of the CC3D Flight Controller to visibly oscillate, constantly trying to level the quad causing a significant drop in overall lift. if the control loop would have gotten calibrated, the flight would have probably been a success.

no damage to the quad itself
