Could I please buy 2 sets of VGs (240 in total)?
I'd like to put them on the wings, horizontal stabiliser (on the underside) and vertical stabiliser (both sides).
Thanks for the VGs they lowered my stall speed by 2 knots and dramatically improved the elevator and rudder in slow speed flight.
I ended up winning the OZ-stol 2021 with our Superstol XL VH-TWL thanks to your VGs among other things.
