| Subject: | Position of VGs on elevator? |
I have test fitted the Zenith sold VGs onto my elevator and after a few
hours of landings, I see only a subtle and slight improvement.
Given that the directions give no exact position, or even a range, I guessed
such that the rear edge of the VGs are 100mm forward of the elevator's spar
rivet line.
Has anyone found an optimal position, or is the improvement only slight?
Thanks,
John Marzulli

John,
I installed the VGs a couple of years ago. I will check later today or
tomorrow for the instructions I received.

John, you might want to check with Zenith.- It's been a couple of years s
ince I installed mine but I seem to remember that there was some kind of gu
idance given for the fore and aft location.- It was a measurement from th
e spar rivet line if I remember correctly.=0A-=0ADoug MacDonald=0ACH-701

That would suggest I need to move my VGs 20mm forward from their current
installation point...

| Subject: | Streamlined struts on 701 |
Hi list members.
I would like to replace the wing struts with a streamlined lift struts
on my Zenith 701. Mostly due to rust forming on the old rounded lift
struts due to nick caused be small locks from gravel runways. I stored
the plane in a very humid hangar for two winters, which cause the
nicks to rust.
I received some streamlined lift struts from a friend who had a
Savannah (Zenith 701 rip off) and thought that since the streamlined
struts have been use on this type of plane for some years without
problems, they should be fine for my Zenith. The material looks very
sturdy and even more material than the old rounded struts I have on my
Zenith 701. I contacted Zenith factory and wanted to order the end
material for the struts, i.e. from the Zenith 750, which is now sold
with the streamlined struts. Understandably, they do not recommend
any other material than sold from their company, and will not sell me
the wing strut ends.
Can anyone advice on what to do? Should I just order the strut ends
from Savannah, or just make them myself from 4130 chromoly steel? I
would prefer the ready made end struts from Zenith, but to receive the
strut end material, I would need to order the streamline struts from
them, which is $1000.
The problem is, when I buy something from the USA for $1000, the end
price when delivered to my home in Iceland with the shipping cost
plus import taxes, the end price has doubled. $ 2000 for some lift
struts is a little too steep for me, even though it would be okay in
USA, but the price of the Icelandic krona is ridiculously low these
days.
Just to give you an idea, to fill up my Dodge with gasoline is $170 a
tank.
I really appreciate your advice.
Best regards from expensive Iceland.
Johann G.

I've seen a number of people leave off every other VG. That is instead of
using a single VG flipped around as the spacer they used three
(backwards-forwards-backwards) as the temporary spacers.
