I couldn't tell the difference before or after. It does make the wing more dangerous.

They do make a huge difference! Although i suppose some may not feel it, but every single plane is better with vortex generators! Good thing is, if you don't like how they look you don't have to install them..... Personally i LOVE how they look, really makes the plane look agressive!

They made zero difference for me. I got them to try to reduce wing rock... they do look awesome though

hmmm, do I slap my mobius camera on and do a half wing with VGs and try this? Not to prove anything… just fopr fun and to video VGs on a light plane.
I'll maiden her without any VG's to see how it handles (before I get to brave). I'll put her up high and stall. I'll try 2 rows with 1" strings and see.

Or I'll just fly it until it meets the dirt. Then mess around with the "to VG or not to VG". High wind and -20s C will finally end this Sunday, so hopefully do the maiden then. Been a crap winter so far.

So yesterday we finally got to +1C and went out for maiden. Tested all surfaces and plane moved about 1 foot and no rudder. After servo centers it has no response. If you flick the servo it responds. Small video of problem. PA wants me to return to the servo to test. Nexatec NXT 80-DSM. Waiting to see what customer service will do.
update….. Shaun from PA is replacing servo. All worked out. Great support!
