“The BLR Vortex Generators have made a dramatic difference in the flight characteristics of the Duke! I feel that I can handle any engine-out emergency on takeoff without a problem.”

– Bill Lovell, Lovell Construction Co.

“The BLR Vortex Generators make a completely different aircraft out of the Duke. I can’t imagine why anybody would not pay the price of one of your kits to make such a big improvement in their aircraft.”
