Jump over to the "other" 701 yahoo group, LOTS of testing of exactly what
you're wishing for has already gone on.

Mine does the same thing and I put X braces on all the olarger unsupported
panels. I don't know if it helped or not, but once you get used to it and
realize that something isn't coming apart, you sort of tune it out. I
calculated what my X braces weighed once, and it wasn't all that much, only
a few pounds, though every little bit helps.
Update on my plane - finished painting it and put the wings back on
yesterday. For the time being I'm leaving off the slats and putting on
JG's VGs! Maybe fly it a bit with no slats or VG's and measure all the V
speeds as best I can, and report later on any differences. It looks a bit
strange right now with the slat hangers on the leading edges but no slats.

My 701 does the same thing. What makes it do that I have no idea, but I do
make use it to control my speed on landings. It's like a built in stall
indicator except no conventional stall occurs, just the big controllable
mush.
Do I wish the wing profile continued over the cabin, you bet. I truly
believe it would be a better plane if it did, as I suspect the buffeting MAY
start there. For one thing I could peer into the wing at a sight glass and
know exactly how much gas I have. I could run a vent line between the gas
tanks to equalize the pressure of the tanks so they would feed evenly,
Cessna does it that way. Does the stall (buffeting) start over the cabin
long before the rest of the wing, I have no doubt.
All in all I love to fly the 701 very much but believe there is room for
improvements in several areas. To be fair you could say that about any
airplane though.

| Subject: | Machining Rivet Heads |
Tommy, Bobkat, Larry and Randy, I appologize for the slow reply but please
accept my belated thanks for all your advice.
I ended up following part of the manual's advice and Mark Townsend's on the
rivet head. I heated them up until they glowed and then took a 135 degree
bit and drilled. Seemed to work fine.
With respect to the primer, I went with Zinc Chromate. I have not opened it
yet, but was told it was the same consistency as paint rather than the paste
like mentioned in the builders manual. Expensive stuff though $200/gallon.
I did find the place to buy an updated manual on the Zenith site as well as
the list of updates to the manual and drawings with the links you gave me
Tommy.
Now, got to get moving on the building.
Again thanks to all,
Perry

| Subject: | Rudder pedal loads |
I'm concerned about high rudder pedal loads, due to a physical limitation.
Does reducing the "vee" angle in the lower nose gear bearing help. I while
back there were some postings about putting springs in the nose gear
steering rods. Did that lower the rudder loads on the ground and in the
air?

Bruce, I'm a 701 scratch builder and am helping build a 750.- The rudder
load is a little stiff at first but if you put a good grease on it during f
inal assembly, it does loosen up a bit with use.- The 701 rudder doesn't
self center and take a little getting used too but after 40 hrs I don't eve
n notice it anymore.
-
During the brief flight I had in the 750 it didn't need much rudder in flig
ht.- It seems to have much less-adverse yaw-than the 701.- Of cours
e, your milage may vary.

Phil: I have almost 200 hours on my 701 and find the plane a little
noisy but not too bad. I agree with an earlier poster, use a noise
canceling head set and keep the weight off the airplane.

I think Larry at Macs Machine shop has a partial solution to this.
He's on most of the Zenith sites.
