It could be better than conventional controls at low speed, dependign on how strong the pressurized air jets are. A bit like reaction control thrusters on a spa

It could be better than conventional controls at low speed, dependign on how strong the pressurized air jets are. A bit like reaction control thrusters on a spacecraft? I wouldn't be surprised if there are even control forces at zero airspeed, with just the air jets acting like reaction control thrusters. Or it might be more like active boundary layer control, just nudging the passing air stream one way or the other with the air jets.
