| Subject: | Rotax carb rubber flanges |
Recently I pointed out that an alternative much cheaper source of carb
flanges was available. I have had input from a knowledgeable Rotax
service agent that non approved parts should not be recommended for use
on Rotax engines. I must point out that I am not making any
recommendation for this product. Normally I, like others, would be happy
to pay a bit extra to ensure that good quality parts are fitted. The oil
filter is a good example. The Rotax approved oil filter does cost a bit
more but it is a superior product and looks after the health of the
engine well. Although carb flanges only need replacing every 5 years, a
price of over =A3100/pair is excessive, hence the desire to find an
alternative. I understand that there have been a few cases of flanges
splitting over the years. In one case a flange failed after the first
start after it had been fitted. Rotax themselves indicate that there are
several reasons for failure even when the approved parts have been
fitted. In particular carb or prop imbalance, too low an idle speed,
loose engine mounts and poorly designed air intake systems have been
mentioned. With all these aspects on top of the choice of carb flange it
isn=92t easy to see what is the dominant reason for failure. I would
appreciate any information of instances of flange failure so that we can
try to detect whether there is a trend.
My opinion.
If the engine has been properly mounted with the carbs and prop balanced
and the idle speed set high enough then the air cleaner (or plenum
chamber) mounting and quality of carb flange might become the dominant
factors. A well mounted plenum chamber (as in the case of the Europa)
should give support to the rear of the carbs reducing the load on the
flanges. Carbs with directly mounted cone shaped air filters are likely
to put a greater load on the flanges. If the load on these flanges can
be kept low the chances of failure are likely to be reduced whichever
version is used. I emphasise this is a personal opinion and, as usual,
the final choice is up to the individual owner.
If I get enough information to show a trend I will publish it on the
forum.
Regards
Nigel Charles

Hi Chaps,
im looking at possibly the purchase of an Airmaster from the factory in the near
future so need a few questions answered , 1 has any one an approximate hourly
life for the brushes & whats the replacement cost for them - i assume its DIY
replacement, 2 was the radio inerference ever cured ? 3 was the oil leak problem
sorted or is it still ongoing, and 3, anyone got a good reason why the Airmaster
should be ditched in favour of the Woodcomp Etc.?

1A. I have done 250 hours in mine so far. No sign of any
brush problems
1B. A spare set of brushes is included in the box. It does
require a soldering job to fit them but shouldn't be too
difficult.
2. I have had a regular click very second or so in my
radio. Never sure what caused it (is this the "radio
interference" to which you refer ?), but I have almost
finished a component change to a different intercom so
that may fix it.
3. There used to be a weep of grease from the hub, showing
up as a very slight line along the top cowling and onto
the windscreen. I cleaned out the hub of that expensive
grease and put in just enough. It doesn't leak now. Not a
lot anyway :-)
Second 3 (!) I have an Airmaster and that is what I
started with so I can't comment about Woodcomp. The
reversing trick sounds neat but not recommended in a
tri-gear with the speed kit (the nose wheel fairing will
turn around and it tail (now facing forward) will be hit
by the propellor blades).

My experience pretty much mirrors Richards, including the engine time.
I have not had any kind of radio interference and the hubs stopped
weeping in short order. I'm 100% satisfied with the AirMaster...

I have over 500hrs on mine.
Mine is an AP308 and I changed to the new AC100 controller at approx 400hrs.
Have never had to change brushes. It is DIY change and I was given a
spare set.
I was at Airmaster last week with another builder to pick up his prop
and they confirm that radio interference is solved and I can confirm I
do not have any with mine.
Oil leak problem is solved.
Mine has operated faultlessly with excellent performance but I have not
been able to compare with Woodcomp.

405 hours. Had to get the computer reprogramed once. took a week and no cost.
Otherwise it works great and has been completely reliable. No problem with
brushes which would be modest cost anyway.

| Subject: | Airmaster questions/ now nose wheel faring. |
Hi! Richard/all
IMHO there's those that have shot their prop. on the nose wheel faring
and those that's going to, reverse thrust or not. Much cheaper to "grasp
the nettle" now and shorten the faring. Whilst you are at it allow for
the prop. getting nearer the faring when the nose leg is depressed. It
doesn't look bad with the shorter faring anyway because it's a smaller
wheel.
I think I took about 3" off mine (before my prop was nackered by the
nose wheel and yoke departing on landing )!
