 I have a firestar 2 and would run out of elevator in slow flight. Then i added vortex generators to the underside of the horizontal stabilizer 
 Tremendous improvement

				Good to hear that, Mike H.
 
 My MKIII is more responsive since I did VGs on wings and lower horizontal
 stabs.

				I had the same situation with my Original Firestar. I first added V.G.’s to the horizontal stabilizer’s bottom side and it worked so well that I did the wings. No regrets, best airframe changes I’ve ever made.
