Rear Door Roof Mounting

Michael Coates
 

A quick tip for mounting the doors is to carefully burn a small hole
through the Fastback fabric with a soldering iron (this permantly seals
the hole) and mount the rear door frame mounts directly over the fabric.

Works well and looks really neat.

Thanks Michael X-Air Australia


Fuel System Picture

Michael Coates
 

Our fuel systems are slightly modified on the standard layout because in
Australia we are required to have a fuel drain system.

The standard tube connecting the two fuel tanks is replaced with heavy
duty fuel hose, the standard hose clamps are replaced with super clamps.

The fuel drain plugs are replaced with hose nipples (metric 6 mm
standard pitch) and feed each tank to a common fuel drain made from a
tee piece and curtis drain valve assembly.

We mount the drain valve up into the bolts which hold on the suspension
swinging arms and the fuel can be checked from underneath the aircraft.

Thanks Michael - X-Air Australia


Neat fit on the Fastback

Michael Coates
 

To get the fastback really tight we leave the frame shown loose on
assembly, when the fastback is pulled into place and the fit checked the
frame can either be bent up or down and then pop riveted into place.
This gives the fastback a really tight and clean wrinkle free finish.

Thanks Michael - X-Air Australia.


Luggage Rack System

Michael Coates
 

The standard X-Air does not come with a luggage rack system (The "F"
Model comes with a luggage compartment as standard ??).

We get a fabric / tent repairer to sew in two zips to the fastback and
attach a sling to the rear of the cockpit. The sling is supported by
aluminum tube on the top and bottom which is held in with cable ties,
the sides are threaded over the normal fastback tubes creating a safe
and sturdy compartment.

The rack will hold about 15kgs in weight without upsetting the C of G
range and is ideal for storing sleeping bags, tents etc..

Total cost around $90 AUD

Thanks Michael - X-Air Australia


How to mount the Dashboard

Michael Coates
 

Every aircraft owner has a different preference for the dashboard
layout, even though we use a standard layout design. It is important to
have the longer instruments like the altimeter etc... in the middle
otherwise at full lock you feet may touch the back of the gauges, keep
the smaller gauges where your feet go.

We cover the whole dash in tape, this does a couple of things...

1. Stops the dash from getting scratched when mounting the instruments

2. By using the tape you can mark out the dash on the surface by using a
texta or marker pen to make sure everything is going to fit where you
wanted it to go.

Another benefit of using tape is it helps the fiberglass and gel coat
from splintering when drilling the holes. I would only ever recommend
the use of a proper hole saw for drilling, the ones with an adjustable
arm will do the job but if they slip you have ruined your dash and i
find they leave a VERY rough hole.

Thanks Michael - X-Air Australia


Which are the right CABLES ??

Michael Coates
 

The phone keeps ringing..... 'Which are the right cables ??'

All the cables are packed in the same bag and some owners cant work out
which cable to use.

The rudder cable has a swaged eyelet at one end and a small shackle at
the other for connection to the rudder horns.

The Aileron cables have turnbuckles at one end and a normal swaged
eyelet at the other... simple when you know how.

Thanks Michael - X-Air Australia


What do i do with the Bungee Rubber

Michael Coates
 

The elastic strap is a bit of a mystery for most owners, basically it's
used to compensate for the weight of the elevators so you get a more
neutral feel in flight and when parked the elevators don't hang down
like some other aircraft.

The bungee is used doubled over and is passed through the horn and then
back along the elevator tube, we mount ours with cable ties as you can
slide (with effort) them up and down the tube for fine tuning. If they
are attached with hose clamps you have to take the fastback fabric off
to get in to adjust the bungee.

If the bungee is too tight the plane will want to keep climbing as it
pulls the control sticks back, to loose and you will need trim to fly
level, just right and it's perfectly balanced for extended hands off
flying.

When adjusting the cord move it about 50 mm at a time until close and
then 25 mm for final adjustment. The cord will need replacing every 18
to 24 months.

Thanks Michael Coates - X-Air Australia


Battery Mount close up

Michael Coates
 

I was asked for another photo of the battery carrier in place on the
aircraft, this one is held in with 6 cable ties rated at 54 kgs each.

With a 300 kg total rating it would take a 30 G impact to break them.

Thanks Michael Coates X-Air Australia


Aerial Mount

Michael Coates
 

The Aerial is best positioned in a central location away from the tail
and the engine, we use a simple 90 degree stainless steel bracket off
the rear wing mounting bolt, the bracket is held in place with a pop
rivet to stop it rotating in flight because of the wind.

This position provides an excellent ground plane and the radio's perform
really well.

Thanks Michael X-Air Australia

Hi All

Some time ago I advised Michael Coates of a very comprehensive locally
produced instrument that I was busy testing on my X-Air. I'm very pleased to
report that the designer Phillip Van Heen is now satisfied that he has
ironed out all the pre-release bugs on his Skydat GX1 system. It's now ready
for distribution. Lets be honest, the "electrics component" involved in the
build process still creates the biggest stumbling block towards finishing
your X-Air in anything close to 100hrs and is the least satisfying. Why?
Because if you do it well, none of it should be evident! Only you will ever
appreciate what it took in time, effort and detail to ensure that every wire
was beautifully soldered, crimped, insulated and where possible - hidden! I
don't doubt for a moment that the more conventional amoung us might prefer
round guages that resemble Microsoft Simulator but surely, if you wanted to
pilot a Boeing dashboard, why fly 'Microlights'. This system is it!
Affordable (+/- $ 1000 US complete), lightweight, trick, easy to install and
very comprehensive. I rest my case. .

My best regards now


Richard Stubbs.

My experience with the Hirth 2706 corroborates yours:
if you assume that a 582 produces 65 true BHP, I would
rate the 2706 at 59-60 only.

G'day Bill,
?
I have doors on my XAIR and find that the cabin pressure is definiteliy lower that outside pressure. This affects my ASI reading and altimeter readins, as I do not have a static line. Do you?
I did the same? Pitot tube tilted up. But that means that as you put thte nose down for higher speeds, the ASI will over read more, than with the nose up at low speeds. If not done yet, do fit a static pickup and dine to your instruments.

Re: X-AIR CENTRAL Re: Questions about the Xair F

Ted Clement
 

Bill, a heads up on the Hirth: A local guy here in North Carolina has been
running the 65 hp one with fuel injection since last year on his Rans S12,
now has around 125 hours on it and I heard today that the crankshaft went
up! Hirth seems to be unable to overcome persistant problems, and no matter
what the company says about how good they are now, be CAREFUL. Not trying
to scare anyone, but I personally don't think they are anywhere near the
reliability of the tried and true Rotax. Its too bad as it is a good
looking engine, lighter than comparable Rotax, and his put out the power;
the Rans with 2 people got off the ground in a hurry. Maybe someday
someone will come up with an afordable 4-stroke.
