Quickie stall speed
Sorry to cross-post this from the Q1 list but I need a fast answer:
Hi Guys,
I have the opportunity to register the Quickie as an ultralight in
Australia, providing I can get the stall speed to 45 knots (51mph) per
our regulations. The specs say 53mph so it's darned close. Can a few
of you please give me your actual stall speeds and any changes that
are known to work to reduce it?
There is already one registered as an ultralight here, but I think the
guy fudged the figures. He claimed a stall of 39 knots which seems
highly unlikely. Unfortunately I can't contact him easily.
Thanks in advance,
Rob

Rob------ My Super Quickie starts to porpose at around 60 with VG.
Probably stall the canard at 55.
Are you sure you can register it as an ultralight?? In Canada we need
the slow speed plus ten Sq Yds of wing. My Quickies wing loading is
only a few pounds away from being classed as "high performance".
I figure the Quickie , at least mine, would be a handfull and an
accident waiting to happen in the hands of an ultralight pilot. Just my
opinion. ------- Canada Chris

Hi Chris,
There's no minimum wing area legislated in Australia, only a
"suggested" maximum wing loading. Since it can't be enforced I have no
problem with that. I take your warning in the vein it was offered, as
an effort to save the neck of a possibly naive ultralight pilot.
However, I've been following the Rutan designs for 25 years and am
very aware of their handling characteristics.
After the repair and fitting of another engine I plan to do a full w/b
and fly off 40 hours as if this airplane were being flown for the
first time. I'll be using a 5000 ft hard runway which has very light
traffic (mostly tow aircraft for gliders) and doing lots of taxi
testing before any actual flight is attempted.
Although I'm a low-time pilot, my basic training was done in Piper
Warriors with experienced GA instructors. I've also ordered a copy of
X-Plane with which I hope to get some feel for the handling
characteristics of the configuration in the next 9-12 months prior to
completion of the repairs. I value my neck, so caution is paramount.

Cris, Rob & All -- Our Australian Ultralight Rules are basically
similar the new US LSA rules but we don’t have the max speed limit.
In a nut shell 544 kgs MTOW , 2 seats, 45knot stall, 10,000 ft max, no
controlled area flying.—The Jabiru J200 is a class example of a top end
Australian Ultralight ( HYPERLINK
"http://www.jabiru.net.au/"www.jabiru.net.au ) -- as is the Cobra
Aviation Arrow ( HYPERLINK
"http://www.cobraavviation.com.au/"www.cobraavviation.com.au )
Cris’s super quickie would presumably have the heavier 503 or whatever
engine and some counterweight.
The original QAC sheet said 53mph power off and 49 power on stall at
mtow --but their planes always seemed to be light and the figures
optimistic.
How much does your bird weigh and at what weight do you get the 60 mph
nod.
John ten Halve has I think about 200 hrs on a Q1 in NZ and did a lot of
flying in TANDEM (:-)) with a friend who also had one. He should have a
pretty good idea of minimum flying speeds.
I’ld be interested to get some comments on this from other Q1 owners on
this. Incidentally can anyone tell me the weight of the ONAN
installation
Cheers

Hi David,
On the other hand, Quickies have been known to be allowed onto the
RAA/AUF register so it is possible. I can also refer you to a website
which claims a stall of 50 mph for it. This does depend a lot on the
specifics of a particular aircraft, and the manufacturer's rating is
only used as a starting point. If the stall can be justified by
calculation or practical tests to be below 45 knots (51mph) then it's
officially a recreational aircraft.
I've been in contact with John ten Have (who lives in Australia now,
btw) and he has been extremely helpful. Considering he's the owner of
one of only three Quickies known to be flying in Australia this is a
good thing. :-)
The Onan weighs 84 pounds. A half-VW at 87 pounds is a very good
replacement. I'm also looking at some other alternatives, like the
40hp DAF and the Subaru Sherpa engines.
