I have read as many "slats" posts as I can find and I don't think this is addressed.
Please do not scold me if it is.
I am considering removing my slats. I may not even add VG's.. not now anyway.
I use my 701 for cruising and really never need short take-off or landing.
All of the explanations I have read about the 701 without slats sounds like an
improvement for the plane AS I USE IT.
My question is.. what is Chris Heinz and Zenith's policy on removing slats? Can
I tell my insurance company that this is an "approved modification"? If I cannot,
then I am sure my insurance immediately becomes useless once I take them
off. Still expensive... but useless.

I can't remember the combination removed slats and no VGs being discussed
here....
That said, I do not think the speed penalty of the VGs is very high.
Vno is listed as 90MPH, Vne is 110MPH.
With slats I get 85MPH cruise, so you can not go too much faster in the
first place.

Personally... If it were me, I would get some of that 12" wide clear hel
i tape and wrap the slats to cover the space between the slats and the w
ing.. That way you preserve the leading edge profile since the slat lead
ing edge is different then the blunt wing profile.. You also gain the ad
ded wing surface area with the slats included and not alter the W&B calc
s.... Theoretically the plane should fly faster and lift more.... But wh
o knows the truth..YMMV.

Go to Zenith's Website and you will find his comments. While he does not
"condem" the practice, he does state that "Performance will be reduced" .
I, like you, do not plan on using the extreme stol features and I have
removed mine but haven't started to fly it yet. Time will tell.

Why not take the "improved" 601XL wing and put it on a 701/750????? I
think it would be a nice flying machine. I mentioned this to R. a long
time ago, he didn't want to say to much------ WHICH I UNDERSTAND
WHY!!!!!!!!!!!!

Ben, I seem to recall this was essentially tried too with less than stellar
performance gains.- Recall my theory that the 701 without slats essentia
lly has a smaller wing and this is where the increase in speed comes from.
- Blocking the slot opening would eliminate the high angle gain without t
he reduced wing area to improve cruise.=0A-=0AAgain, I'm just remembering
previous conversations so take what I am saying with a grain of salt.=0A
