701 with VGs instead of slats

[LTF85199]

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.

[STOLSPEED]

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

[STOLSPEED]

VGs is short for vortex generators.

Ask Google.

[PuertoRicanVideo]

@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)

[denizzzka]

What is VGs?

[STOLSPEED]

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

[aodhanof90]

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

[ushouldntjudgeme]

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

[kazakhpilot]

I like to fly my zenair 701 more with the slats on airplane (it shorter take off and more steep climb). I try it both with and no slats.

[ChrisMiller1994]

sorry for the stupid question... but what are VGs? thanks...

[TogieTung]

@ChrisMiller1994 Vortex Generator, for visual examples type AIRTAB..

[TheRooster602]

search for "youtube aspect ratio fix" - the proportions are wrong, the plane is not that stubby.

[mrsmelzbad]

is this airplane comparable to a cessna super-cub? cost? Im from alaska looking for a bush plane that doesnt cost as much as a cub.

[madisonelectronic]

You could land this thing and not hurt the ants on the ground.

[jonny2387]

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.....

[airfoxultraleves]

Hello @STOLSPEED , I have a CH 801 and I would like to install the VG on it, do you have VG to CH 801?

If you have, please contact me on my e-mail lenabeto@uol.com.br

[davetileguy]

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

[justanotherengine]

Oh man, that's a cool little plane, I always wanted to learn to fly, you seem to be a very "Skilled" pilot, always admired you guy's !

[OnlyGokhan]

zenith awasome!

[STOLSPEED]

Never had a tailstrike in 500hrs of intensive STOL flying.

[paranoidandroid1995]

on T/O, the tail got pretty close. i wasnt doubting your flying skill.

[paranoidandroid1995]

tailstrike?

[STOLSPEED]

Never had a tailstrike in 500hrs of intensive flying.

[TogieTung]

@paranoidandroid1995 It is when aircraft's tail "scrapes" the ground during take-off

[stidbi]

where can I get one? Is this a homebuilt?How much do they cost?

[eightyknots]

Hi, I wonder how an "original wingspan" CH-701 goes with VGs (and no slats)? Do you know any people who have tried that?

[MajorTiga]

oh c'mon man my model takes a longer way to get airborn and it ways round about 20 kg^^

[STOLSPEED]

The glide ratio with the longer wing and VGs is 7:1.

With the original wing with slats it was 5:1.

A slip with the VG wing brings the glide ratio down to 5:1 for a steep descent when required.

Cruise without slats is 6+kts faster, and stall speed is very much the same as with slats.

[mrbizi]

what's the glide ratio of this plane?

[bbuck54]

Does your wing without the slats have any better cruise? Are the stall speeds similar with slats and vg's? Nice plane.

[STOLSPEED]

Slats or VGs can pull the same angle of attack, so risk of dragging the tail is the same. No problems with the prop on landing - nose is way high, as you can see in the video.

[mynameiscaleb]

i wander how many people rip the rudder off on takeoff and the prop off on landing.
