Zenair Zodiac 601HDS with Vortex Generators installed

Flight test with Vortex Generators instaled from stolspeed.com on Zenair Zodiac 601HDS. Lift-off speed on T/O is reduced more then 10kt, stall speed is 10kt lower, approach speed is 10kt lower and landing touchdown speed is 15kt lower as before.
New speeds with vortex generators are:
Take off lift off at 40kt.
Stall with idle power 40kt.
Stall with max. power 35kt with extreme nose up attitude.
Landing touch down speed below 45kt.
The VGs increased the flight safety extreme over the whole flight envelope. Rate of climb is much better, at the same cruise speed lower fuel flow and the nose is 3° lower (better foreward visibility) The best modification for few money.

All my videos are to demonstrate how much safer and better performance I get with Vortex Generators installed.

If you press more under About This Video you get more informations. I have soon 1000h in the air with my 601HDS. Endurance is over 8hrs and I fly a lot around in Europa and Afrika.

Did you lost cruising speed for the same power setting with the VG´s?

[MetaView7]

does that means I can have the best of both worlds ???

i.e. get the higher performance of the speed wing, and the slower stall speed capability of the constant cord wing?

I was already a believer but...wow.

Nice job!
