Re: X-AIR CENTRAL Re: ETG Probes & their positioning

Xair Ontario
 

Thanks Richard,

I know I have the probe bosses in the right place as I've measured them from
factory units along with photographs as proof. I've just been informed the
engine will run hot for the first 25 hours or so because of the Nicasil
coating. 1300 degrees is not to be passed but 1200 is normal at first.

I'm still going to hook up an E.I.S. to see if they read the EGTs any
different.

positioning

Hello Trevor

As a general rule of thum, the position of your EGT probes needs to be 100mm
from the piston skirt. Establish the distance using a vernier from the
piston skirt to the end of your exhaust port and then add the difference
along your exhaust manifold to make up the 100mm not forgetting to include
the thickness of your gaskets. I don't know the Hirth motor although it's
success here in South Africa was short lived. I would like to suggest that
you contact the manufacturers of the "Hornet" fixed wing (the one that
resembles a Challenger) as this company has used the Hirth engine as
standard fare for many years and would seem happy with the product.

Best of luck

Richard Stubbs.

Smallproblem though...


Hi Guys,

I flew my plane today!

All was well except that I'm getting high EGTs. I'm running a 68" GSC wood
prop with 16 degrees of pitch and a Hirth 2706.
Both plugs are brown and not wet. The needle is a 15K2 and the main jets are
160s. I'm getting 1300 degrees on the EGTs at 6100 RPM and it settles to
about 1200 at cruise (4200 RPM) and 400 on the CHTs either way (I did see
the back cylinder go to 500 once). We've tried 170 main jets hoping to run
it richer to get the EGTs down but it made no difference on a second
circuit. Judging by the plugs we are running just fine. The engine seems to
running very well with no indication of wanting to quit (I know go ahead and
laugh, I know Murphy's Law very well thank you!)

I'm using the Mikuni pump and I also have an electric pump but have not
found that it makes a difference. We are wondering at this point if the
location of the EGT probes is causing a high reading. I welded the bosses
about 80 MM from the head gasket (verified with pictures taken of other
Hirths at Sun N Fun). My assistant tells me that the further away from the
engine the probes are the higher the reading because the fuel is still
burning on exhaust. I've looked at a 503 and 582 and the probes are much
closer (more like 30 mm) to the head.

We are thinking about hooking up an EIS with their probes to see if they are
reading properly. I'm using Westach gauges and probes.
Anyone have any suggestions otherwise?

Trim Cable Modification

 

Gday again,

There have been a few questions about the trim cable lately, in
particular hoe to stop it slipping, we drill two small holes through
from the center of the pulley to the outside edge of the plastic pulley
and thread the cable through these holes. The additional friction stops
the cable from ever slipping, and the modification takes about 30
seconds to do.

I hope the pictures help explain the procedure.

Thanks Michael X-Air Australia

XAir Main
 

HI Bill,

I broke in my Hirth today. I had a few problems with the carbs but it turned
out to be my mistake. I put the needles in after the plastic retainers! The
engine ran too rich and barfed and so on. Once I discovered the mistake and
put the needles first, all was well.

If the wind dies down for tomorrow morning I'll take up for the first time.

Talk to you soon!

p.s. How's your plane working out. Got the kinks figured out yet?

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.

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.

to see the other factors such as prop adaptation,
elevation etc.. I don't know...
