| Subject: | 601HD for sale (soon) |
Hi folks, just a heads up to let everyone know that I'll be putting
up my 601HD for sale soon. The flying season for up here doesn't
really start until late April so I'm not in a rush to sell it now
but invariably some people might be interested in the spring.
I have a whole laundry list of things in the plane but the basics are:
80 HP 912
Czech Aircraft Works cowling system
Forward opening canopy (same as the XL)
50 hours TT
Full VFR panel with intercom, ICOM Radio and Garmin GPSMap 176
Price will be in the $34000 USD range
Anyone interested can contact me off-list

| Subject: | VGs feathers on an 801 |
Craig
The suggestion was made that the tail was stalling before the wing. Adding more
smaller VGs tested this theory.
You are correct the stall speed did not change but I already had VGs on the tail.
The VGs on the tail give you more elevator authority at very little cost.
For example adding VGs to the "original" small tail for the 801 gives you more
elevator authority than changing to the larger tail.
15 years ago everyone "knew" the only reason to use VGs was to correct design mistakes.
Today they are used as a high lift device and to direct vortexes when
desired to reduce drag.

Aren't VGs on the tail surfaces used for correcting control issues, not for
changing stall speeds?

Subject: Zenith-List: VGs feathers on an 801
I finally got time to add 100 VGs to my tail to see if that makes a
difference. It did not seem to make a difference. Here is a summary of my
testing. I only stalled the plane 3 or 4 times in each configuration. The
numbers should be within a mile an hr or two. The winds have been light
when I have done the testing. I used GPS speeds. To calculate air speeds
at high altitudes I assumed the plane's speed would increase 3% per 1000'
rise in altitude.
Removed Leading Edge Slats off the CH 801
Installed home made VGs 10% of chord and at a 45 degree angle
Stall clean 55
Stall dirty 43
Cruise I 108 MPH GPS 103 MPH
Density altitude at 3000' +500'
Cruise at 4500' Standard day 115 MPH
Installed feathers at 10% of chord at 12 degrees
Stall clean 51
Stall dirty 45
Cruise I 110 MPH GPS 104 MPH
Density Altitude at 3000' +1500
Cruise at 4500' Standard day 113 MPH
Installed Feathers at 6% of chord at 12 degrees
Stall clean 50
Stall dirty 45
Cruise not measured
Installed Feathers at 6% of chord at 12 degrees
Removed large VGs from tail installed 100 smaller home made VGs at a 15
degree angle
Stall clean 50
Stall dirty 45
Cruise I 105 MPH GPS 103
Density altitude at 3000' +1000'
Cruise at 4500' standard day 114 MPH
Take off and landing distances are definitely longer. They are a lot
shorter than a Cessna but...
If you factor the cruise to 6000' you would be 122 MPH. The plane seems
slipperier. Not like a Bonanza or Mooney but more slippery that it was.
Before VGs I used 50 as my final approach speed now I need to use 58 mph.
Is loosing 8 mph on the bottom end worth gaining 10 mph on the top end?

I get distracted from building on occasion and have
decided to share some stuff with other like minded
individuals.
I've created a LSA Experimental Kit comparison page
with similar type aircraft. It is what it is. Go to
the following address to view.
http://www.iflylsa.com/
And I have an Excel spreadsheet configured to track
building expenses. It's commented (red tag indicates
comment), with sample numbers. Feel free to use and
share.

If all goes well my XL will be flying sometime in
April.
If you have comments or questions please contact me

Hasta la Vista!

A while back Brett Ray (brett@hog-air.com) made a Harley engine conversion
and put one in his 601XL with a twist throttle. It uses a friction lock and
he seemed happy with it. He has since sold the plane and is no longer on
the list, but if you were really curious the e-mail may still be valid.

Has anyone ever tried a twist throttle on the stick?

Hello all,
I'm a newby to the group but here is my experience with the twist throttle.
A few years ago I flew an Ultralight (Aerolight 103) with a twist grip
throttle incorporated into a break lever (tube, pull up for breaking) on the
left side. So my left hand was twisting for throttle and flying with right.
It also had a friction lock but made the twisting difficult. Although it did
the job it is not intuitive as the standard throttles are. I found myself
twisting in the wrong direction many times. This was not good but I had
plenty of time to correct.... My opinion is the standard throttles. Oh, the
factory discontinued it shortly after and went to standard throttles.

worked real good... if you have a center stick. , u you twist it open to the
back, just like on a bike. it helps to havea push pull cable set up carb.

Why would the hinges be in the rear of the wing locker instead of the front. That's
about the only way I could imagine the door coming open.
I've taken off without fastening the wing locker door (not intentionally) and it
just hugs the wing in flight. I circled back for a landing and popped them shut.
No biggy. Of course, the hinges are forward.
