VGs on a Rans S7 or S9 ??

[Guest Maj Millard]

I have a customer who has purchased a Rans S7, which he uses in the mustering role. He has asked about the use of VGs on it to delay the stall a bit. Does anyone have any experience with VGs on the Rans wings ?. I have flown the Savannah VG so I know they do work........Thanks.. Maj...

The RANS S7 owner & builder isn't a fan of the things - he says they only give you 5 kts at the best and increase drag and end up with more muck on the wings. He's never been a fan of vortex generators, or other STOL gear on an aircraft that already has a low stall speed. That's only his opinion, others would disagree.....
