Good day JG

My VGs are installed now. Yesterday the first testing without wind are :

...........................................................without VGs..................with VGs

Stall speed  with flaps clean                     75 km/h                     65 km/h (35 kts)

Take off...........................                       very short                   about 1/2 as long

Landing with flaps 2 .......................    final at 100 km/h           finale at 85 km/h (but could be slower now)

Cruise at 5800 rpm                                   150 km/h                     150 km/h (81 kts)

Good balance now with the VGs under the horizontal stabilizer.

 

Landings are much easier and smoother, just float on.

I have placed the first 18 VGs spacing at 60 mm and the others at 90 mm. All at 84 mm back from the leading edge as you can see on the picture join.
 
Thank you JG

 

Francis, France
