The thing has very limited endurance, something like 10 to 12 minutes at best, and a 10 something mile maximum range.
He has to refuel just to make the 22 mile trip across the Channel.
It also has a limited lift capacity, so what you saw was about it as far as load out goes.
Also, it is a bit on the noisy side, so much for sneaking up on someone flying one of those things.
For that to be practical, they would have to "swarm" a position with many of those hoverboards, to be effective.
Swarming is exactly what I see happening. And as someone mentioned, the tech will get better - longer ranged and with more lifting capacity. Just build a motorNOTcycle like machine for the operator and attach weapons to it.
