Not sure about the legality of the strat, but the robot itself is legal.
This year, unlike previous years, flight was not expressly banned. The bumper zone applied as if the robot was on the ground, so flight or high jumps are fine- just don't leave anything hanging.
However, early in the season I calculated that to safely make a flier you would need at least 18 775pros to avoid burning them out just flying themselves and control system + battery around, and this isn't even including main breaker issues.
