Subject: | Original (kit form) transporter? |
Wondered if anyone had an original design of transporter they would sell or swap?
I have a fully assembled/welded trailer but almost no space at home to store
it, hence would like to change to a 'deriggable' version. Any condition considered
. . .

Subject: | Monowheel undercarriage 'up' stop? |
I'm doing the LA mod to the tunnel which lets me see the lock up and lock down
operations of the UC in more detail (through the sidewall holes presently cut
for the mod) than one can normally see from underneath the a/c. I notice that
in the locked up position, the tundra wheel is still free to move upwards about
10-15mm before the calliper brake hose union contacts the fuselage in the area
of an encpasulated rudder cable run.
Apart from the possible irritation of hearing 'bumps' in the air as the wheel moves
up and down a little under varying G forces, it made me wonder about what
happens in the case of an intentional or unintentional wheels-up landing, and
that such a situation may at least reduce controllability as the UC articulation
takes out one rudder cable - and indeed after that- a that it might then go
on to contact the throttle lever moulding etc.
Could anyone comment on if they see this as a real concern or not, and if any potential
up-stop solutions exist? Views of anyone who has had the misfortune
to repair the damage caused during a wheels-up landing would be especially welcome.
Also wondering about if a mudguard fixed to the arm might be good idea
?

A bit of a random question:
Does anyone have a set of XS wing trailing edge top skins lying around in their
workshops surplus to requirements?
Please get in touch if you do.
Thanks,

I havent noticed any bumping about of the wheel in flight. I have filled the tunnel
with snow and mud before now and am glad there is some spare space up there.
There are some mud guard designs around and i have wondered about one myself. Id
be interested to know about the mod you are doing.

I'm building a classic mono wheel and am interested in a mud guard sort of solution
too. The only one I know of was made by Kim prout but I have not made any
head way in trying to contact him about it. On the well documented Tony K's site,
in one of the entries he has it fitted.......looks quite good too.

Jim Naylor built Classic Monowheel G-BVLV and later fitted a particularly attractive
and effective mudguard.
If memory serves me correctly when I spoke to him about it, he said that he laid
some material over the inflated tyre and then took a moulding off this to form
the mudguard.
He has sold the Europa and moved to NZ so we can't find out too much more, but
a trawl around the net might come up with some photos.

Subject: | Airmaster constant speed unit issue |
My 912S has an airmaster VP prop with warp drive blades and the airmaster constant
speed control unit. Both have around 100 hours on them.
Today upon takeoff fly flydat alerted me to an engine over speed (moderate; never
exceeded 5900rpm). I slowed down a little and reduced power to keep the engine
within limits, and climbed to altitude to consider the issue. The CS unit
was non-responsive, however switching to manual enabled me to alter the pitch.
Has anybody experienced this? I assume that if all connections appear good, I
simply need to replace the CS unit?

Had same experience and vaguely recall that the CS unit was reprogramed and returned.
Was done here in states. Have also had wire break going to the prop motor
and it stayed at same rpm ..no problem to finish flight.

Have had this problem a few times.
In the first instance make sure the slip ring is clean and free of oil or grease
deposits. A quick wipe with brake cleaner will sort this. Then clean the slip
ring tracks with a green plastic pan scourer. Ground run to check function.
If this does not work check your brushes as per the prop manual. This cure is
as per Airmaster.
Hope it works for you.

Hi Rick,
I too have had this issue on 2 occasions at about 35 hours and 140 hours -
worked OK on manual so no problem continuing to fly. On both occasions
Martin at Airmaster replaced the controller for me free of charge. After
the second failure I asked him whether there should be a switch in the prop
controller circuit to prevent any voltage surge during starting and he said
this is not considered necessary, but in view of the 2 failures it might be
a good idea in case there was some unusual issue with my installation. So I
put a switch in the circuit and keep it switched off during engine start and
stopping, and since then (now 380 hours) I have not had the problem again.
Regards,
Keith Hickling,

Rick,
9 times out of 10 the brushes have oil on the slip ring or have worn until
barely contacting ( typically the outer ring brush wears first). In Manual,
you get direct battery current, so it will give you more juice to burn
through any corrosion/oil. Clean up the slip ring and check your brushes.
Normally you get red flashing lights with an open circuit, but not always,
because if there is some current, but not enough to move the prop, the red
lights don't flash and the prop doesn't work in Auto. (As I tell my
clients, Red lights are bad, don't takeoff, if in-flight, go to manual and
adjust the prop manually or by throttle to keep the RPM in limits and land
as soon as conditions permit and investigate.)
I have had three calls or comments since the weather turned cold. The oil
layer thickens up and coats the brushes. As brushes wear they also
distribute carbon to the inside of the brush block.
Oil helps hold the carbon as a current drawing sludge which acts like a high
resistance wire. Current can then jump between brushes and stop the prop.
It's basically shorting. Not good for the AC200 either.
Every oil change, check your brushes and slip rings, as any leak of oil will
often times go forward through the large hole you made in the front of the
cowl. It only takes a thin film of oil. Clean with acetone on a clean rag.
Clean the slip rings with scotch bright to remove corrosion. Wipe clean
again. Use air to blow off the brush area in the brush block. I pull the
brush block off and check the brush length on my annual or at 100 hours,
whichever occurs first, not just when the prop stops working.
Technique:
To help seal the prop from this nuisance oil film, use some fiberglass to
try to seal up the hole. To seal the hole, I have had success with using
silicone cowl seal (in sheet form with a fiber reinforcing to keep it stiff)
on the lower cowl. This silicone rubber gives me some flexibility when
getting the cowl off of a trigear. On the upper cowl, just make a 3 ply
sheet and allow to cure, then trim and fit to the shape and glass on the
upper inside... Go Fly!
If the pickup for the speed sensor goes bad, that freezes the controller.
The fine orange light should flash. If the speed sensor is bad, the brush
block usually needs to be changed.
If the controller dies completely, the internal fuse (a PTC that resets
itself) may have opened (at about 2.5 amps) killing power to the controller
until it resets itself by going manual, cooling, and then back to auto. If
you are using thick grease (Aeroshell 22) that can stiffen up as it gets
colder and cause a power drain, but that's unlikely. Cycle the prop in
manual and listen to the motor. If it is dragging, it may be too tightly
torqued or the grease is really thick. If the motor sounds good and free,
the AC200 is not getting power or internally dead. Check power to the unit
(CBs do go bad), if OK, check the circuit breaker on the side of the
controller. If that is OK, and cycling manual to auto doesn't reset it,
it's probably a dead AC200.
We often say the controller was reprogrammed, but often times the circuit
card is replaced.
Check the above and have a beer and dive into the manual. It's on line
also.
It's winter, in the northern latitudes, so stay healthy and let me know what
happens after troubleshooting the above... We're enjoying 75 degree weather
here in Florida.
