I'm quite sure the vortex generators will bring down the unloaded rpm but in theory they should increase the width of your rotors "sweet spot". As you load the alternator the rpms come down in relation to windspeed decreasing tsr and increasing appearant wind angle. Your trying to increase how far this can go before the rotor stalls badly. It should work but my only comment is possibly related to the height of the vortex generators. They are supposed to sit within the boundry layer at low AoA's so It's possible to assume yours may be a hair tall. I would guess based on some tripwire experiments I did that an eigth of an inch should be sufficient. Could be wrong but the fun is in the experimenting.
P.S. It's nice to see someone playing around with these things.
