Hi,

I'm Bill Magrini -- Xair Dealer in the US fort Virginia and Maryland.
I just completed my Xair F and have flown it twice. I Didn't set the
prop thrust line up properly, so it wouldn't climb so hot with two
people. I'm still tweaking the bird. I hope to have it all correct
this weekend.

Regards,

Bill

Yes, the gearbox was in the up position, plus I had a tad bit of down
on both ailerons.

I have found when setting up the ailerons, which is very important to have
right, that the best way to do it is really with three people.

Position the stick centrally and tie in place, tie it firm because it's

to move the position when adjusting the ailerons. Using one person on each
wing, go to the outboard location where both the struts connect to the wing
and put a good straight edge in there - wedged hard against the leading and
trailing edges.

You can now use these secure straight edges (piece of timber etc..) to
adjust the position of each aileron. The factory recommends touching each
straight edge but our preference is to have them raised about 1 cm (1/2
inch) i find the plane flies a little faster and seams to be very neutral

all aspects of flight. If they are adjusted down to touch the rulers the
plane seems to yaw a little bit in the turns, adjust them up and it

Finally, don't forget to safety wire the turnbuckles using a standard

8 wiring method.

Your done !! she should fly perfectly balanced and without any vices.

Thanks Michael

Find long lost high school friends:

Just to clear up the information about the engine brackets. Bert
Floods has agreed to design a bracket which will fit the Rotax 912,
if
and when we start ordering 912's for our aircraft. Our conversation
went something like, if you can come up with an engine mount to suit
our aircraft then i think more customers would consider a 912. I dont
think Bert Flood's would like to put the work into a bracket if it's
to be used on an opposition engine.

I will do two things. 1. Ask the factory in France for more
information on their mount, and who made it, can we have drawings
etc... and 2. Put the word out to find a suitable person to fabricate
a new mount specifically to suit the Jabiru and Rotax 912 engines.

There are that many planes out there now flying around Australia i am
sure if either engine importer got there act together and did a mount
then their engine would sell in reasonable numbers. Every customer
asks the same question.... Can i put a 4 stroke on the X-Air ? and
why
wont the Jab or 912 bolt straight on !........ if it was as easy as
saying the Jab/912 will fit with the optional $300 engine mount then
i
am sure they would buy them.

Easy way....... find someone who can design a mount and do some
welding.

Thanks Michael

Hello Tony,
?
Saw your message re 912 bracket. Do yo know how much Flood wants for it?
Appreciate your advice.

Anyone got true performance figures to compare the 618, 912 and the

Jabiru 2.2?

We had a Thruster T500 at our airfield that had a 912 mounted. It

seemed to work

OK (I flew in it), however I couldn&#92;'t help think the advantages of

the bigger

motor/prop may have been negated somewhat by the drag/weight

increase.

Ofcourse, no one can dispute the 912 reliability though, which is a

big bonus.

My experience shows that the 618 and Jabiru are very similar in
performance - although the benifits of near silence in cruise is
appreciated over sensitive areas.

Our Jabiru performes very well except for climb and this directly
relates to the engine mount which makes the thrust line to high (the
propeller sits too high) if the standard engine mount was replaced
with a new one to specificcaly suit the Jabiru engine then i am sure
it would perform better in climb.

The 912 i expect would perform very well but no-one has done that
instalation in Australia, both the 912 and the Jabiru are heavier
than
the 618.

Fuel consumption is nearly identical between the Jabiru and my 618
although some of our customers are using up to 18 liters per hour on
there 618's ?? - (they probably need to be set up a bit better).

I am sure if someone could come up with some sort of engine fairing
for these engines that better consumption figures could be acheived.
If you look at the size of say the Jabiru hanging out the front and
imagine the wind resistance..... it must have a big effect

Hi I am Darrel Peatey the Xair dealer for Tasmania I would like to
hear from other people with similar interests.
