What was the results?

Did it create the same climb performance as the slats while reducing weight, does it reduce cruise speed as a result?

[STOLSPEED]

@LTF85199 Rate of climb is 140fpm better with VGs instead of slats. Cruise speed is 6 kts faster at the same power setting.

@LTF85199 For detailed test results go to the website shown at the beginning of the video, 'Slats/VGs' section

VGs is short for vortex generators.

Ask Google.

[STOLSPEED]

Yes you can use both VGs and slats. With slats still on, the VGs make no difference to performance.

if your ever in miami with this plane let me know im dying to find someone to get a ride

[STOLSPEED]

This aircraft is in Australia, so probably won't get to Miami, sorry.....

@STOLSPEED Google VGs and you do not get vortex generators. Acording to Wikipedia: VGS may refer to:

US-skacore band Voodoo Glow Skulls

Volunteer Gliding Squadron

Virtual Game Station

Vince Genna Stadium, a baseball park in Bend, Oregon

VGS means gate to source voltage in field effect transistors (electronics)

What is VGs?

[aodhanof90]

can you run VGs with the slats still on? I'm think about building the tail for the 801 this coming summer :-)

@STOLSPEED fly it to the U.S.!!!!

Wow, I saw three CH701's yesterday at a Fly-in, those tails are way up there, now I know why! Awesome airplanes!
