I've had it happen in the car, usually in light fog when the windscreen is cold. Check the meteorological conditions at the time, particularly dewpoint, temperature and humidity. It probably takes just the right (wrong) conditions and a cold windscreen.Scary stuff. Good that you thought to use your instruments and that it didn't last long.

 

I use a Shell windscreen cleaner / polish. Never seen anything like it, but have heard of similar close to a snow cloud.

yeh your right!I had already checked and was forcats patchy fog,but theres was none present as I have No door on the hanger a good indication is if my planes are fogged in their,this morning they were clear,I know what causes this after speaking with mt Pa, what happens is inside my cockpit on the ground the air temps are equal and as I lift off from groundthe aie becomes cooler, but my cabin temp is warm and widsceen cool so fog(condinsation)builds quicly on the widow and when the cabin temp matches outside it defogs and becomes clear,the problem is inadequet ventilaion, as the thruster has NONE and the supercat(worse) has a small side vent which creates a low pressure. so need a smaller vent in the front to allow air in and the bigger side vent to exhaust,should equalize pressure diff.

 

 

I would be looking for the cause and fix that as well as using vinegar...it's just that I am getting an uneasy feeling about all this Flyerme...please be careful!

funny! me too. really starting to regret this supercat!!! sure would love an orthority on them to check it all over? should mention have had this happen twice before! in the thruster,if you look at my you tube video of the thruster flight to new runway youll see clearly that on take off from NEW strip the window fogs over! thats NOT the cam ou of focus,its a fogged over wind screen, anyway would appreciate any help with this supercat!surely theres someone out there who can help sort it out? sure sucks financually being a full time carer sometimes. oh well can only do what I can and continue in small leaps antill she sorted,,hopefully sooner than later,unfortunatly I must Now make a very hard descission! Do I sell my pride and joy?(thruster T83) I need to pay out what I owe on the super cat and might have somthing left to fix it up with. hmm

 

 

Ok been up another 2 times after removing side scoops and replacing bottom of cowling, still the same but I think I have an idea whats goin on? asi out? first landing noted thottle off and nose her over and she wants to continue?needing a lot of back stick to hold her,but give some throttle and she seemed fine? first landing nice,but noted asi,stuck at 60knts and then joollt down to 50 knotts? second fly,landing came in at 55-60 knotts and noted wing drop a couple of times and plane felt very slopy.ground speed seemed fast but as I set 55 knotss(50 being real appoach speed) at around 20ft hight she started to shutter and droped on the strip, I bounced back 10ft gave a lil throttle ,levelled and put her down gently. really sus on the asi? but felt nice and stable in level flight set at 60 knotts,noted engine sets pitch?drop revs and she noses over give her throttle(NO stick) snd she instantly climbs. sure do wish it like the trusty thruster on approach?went for an awesome fly in the thruster last night and set approach and was able to take my hands off and pour a cupper and eat some bickies on the way down...well almost..

 

 

went up again ,this time cleaned thw windshields with white vinigar and seemed to do the trick,

 

 

Holly Crap Batman.......took off this morning in the supercat,7am, at around 10-20 ft after takeoff ,My windshields(front sides and back all completly fogged over,it was on the out side and their was nothing I could do?No I could not open door as the roof would blow open and upset aerodynamics,it has a small vent which was already opened. any way I satarted to sweat as I scanned the instuments and continued to climb,looking out the small vent ,I could only see the wing! so i climbed to 1000ft and levelled still in 100% blindness,and I put my hand threy the vent hole and rubbed a small window (left side window and was able to get a rough visual and just as quick as iy came it dissapeared,got a lil fright so made a turn(was now 7 kms out) and headed home,set my approach and descovered my balance issues?if you drop the rev right back and push the nose over she wants to continue noseing and need a lot of back pressure to hole her,but if you level out a bit (say 10-15 deg pitch) she flies centre stick nicely,so set a approach at 10-15 with 3500 rpm and wow..what an awesome lil plane ,Now was going to go up again now suns out but looking out at my super cat ,the window completly fogged again and the door is open,must have its own climate in their? lol.so I will buy some de fogger wax and give it ago? any other suggestions, and has this happened to any one else? Now do I get indourced for instrument flying now?LMFAO:roflmao:

 

 

I thought I'd reserect this thread to see if anyone knows of or has a private strips where members may drop in (pre arranged of course).I'm hunting down a number of strips in WA to check out in the future. Anyone here got a strip for members?

yeh I got 2 seperate stips but both short. No 1=My home private strip, sherlock S.A 5301=320meters and No2 my second property=Peake S.A 5301 = 250 meters.

all welcome

 

 

Hey Alan, hope all going good now. Unfortunatly being a full time carer for my in=laws and recieving a small pension ,both distance and money where my exuses,,would have loved to fly-in in my trusty thrusty T83 single seat single surface wings(she gets a lot of attention) anyway.next time if the gods smile upon me..

 

 

OK hight explained! He is doing a tour to W.A(its new home) and will be flying low when possible for ground viewing...thnks a bunch the ground viewing was awesome

 

 

Spoke to another nieghbour who also seen it,he said it was on channel 7 news last night,it landed at lake alexandreena(near meningie) it was a ww2 ALBERTROSS flying boat on its way to W.A, with new owner piloting,,,what an awesome site and the noise, a site i'll forever remember..wish I had the cam.

 

 

Yesturday while my son and I where driving to Peake , I noticed a plane heading toward us,I stopped and we got out to witness a catilina flying boat at NO more than 300ft fly over us!! It was white with light and dark blue detailing,the twin engines sounded like they were idling and holly hell was it loud! I really thought he was in trouble and coming down..but he continued into the distance,it seemed to be heading toward meningie.weather was slight shower but nothing that would have him down that low.never seen such a big aircraft(thats not at an airshow) flying that low..glad I was NOT in the thruster on my way ..I like to fly low at 5-600 ft to peake..hmm will keep a extra eye out for traffic...

 

any one know anything about the flying boat?

 

 

I am a qualified automotive mechanical engineer, but made my living working for E.T.S.A(rural electricity meter reader),unfortunatly ,I had to quit and become a full time carer for my intire in-law family..Mother in law(passed away cancer aged 48-last year) her son(brother in-law - with aspergers) and my grandfather in-law(elderly -body only ,mind a wealth of nollage)..so hence why Im home 98% of the time. and my grandfater in-law (PA) is my biggest aviation supporter...he has just completed a 250 mtr strip for me and is talking about a hanger,in case the weather turns nasty ..

 

 

found it..you can stop looking now? c of g...lol 25%(12")-35%(16"),ideal 30%=14.3"....

 

my c .of g =1/2 tank fuel 14.7" full tank =13.2 " empty =15.1" so all within range....hmmm so I have removed side air intake scoops,and refitted bottom of cowling ,also re measure of engine mounts and engine sittin 4mil higher..will lower back 4 mil today and have it ready for test 3 thurs....

You really should fix it. It's not the only plane that has a massive CofG change with fuel load in a forward tank. If you get them tail heavy when the fuel is low it's much more dangerous, than front heavy. Nev

Hey Nev,just before this flight I drained 17ltrs leaving 25 ltrs in tank,(have flown with 35 ltrs no issue),,the new engine is identicle,and now has had a piece of exhaust removed and the pullstart bell removed so should be less wieght? only thing different is 2 air intake scoops on the each side of the cowling?also the bottom of cowling has been cat away(for more air exhaust),but it was noticed by another pilot test flying with NO cowling,he noted nose heavy? engine is sitting in exact same position?yet another super cat mystry.....can,t find the c of g any where???????????????????????no info???? wieghed and messured today and just starting the number crunching, first 2 calculations came up 4.56ft and 4.62 from datum(front of prop mount, this puts th c of g 3 " behind the leading edge..(about 8%) Im guessing it that c of g should be aroung 25%?

 

 

thanks Flyerme. Quick flight, not the best weather conditions though. That cat sure does skid around corners don't she. All the same, very nice landing.

Hey Doug,thats not the weather....it was smooth but I was fighting to keep the nose level,notice in turns skidding and nose kept dopping ,,landing is all plane(NOT WEATHER) nose kept dropping and needed almost full elevator and throttle bursts to keep nose up..to round out I neede a quickburst to get the nose up for flair and full back pressure.

 

 

Where is the camera on that? How is it mounted? Beautiful video, glad you made it back down safely ;)

Its mounted on the tail..air race style..lol fibre glass tape.lol

 

 

Took th supercat up this mourning,and defenately nose heavy! notice the s;ight porposing on take off but approach mderate porposing needing throttle to keep her up,had to look back to confim elervator was doing what stick was..enjoy

 

 

 

needing the c.of .g -mac..for the first strike suprecat/bobcat..Ive had her back in the air finnally, but with a full 45ltrs of fuel up the front she was very nose heavy,approach was made at 50-55 knotts but needed a fair bit og back stick to hold her just before round out set 50 knotts pulled back to round out and nothing? she continued inyo the ground,full back pressure applied but she just sank gently into the ground-No round out_No bounce, definate stall,a quick glance at ias on touch down still over 40 knotts (stall in normal configuration is 37knotts).

 

any way any info on these beasts much appreciated..having a hell og a time getting info?

 

 

A cold seizure can occur if an engine is run at full power before it is fully warm, the piston then expands faster than the cylinder leading to the seizure.

 

cold Seizures explained

 

The text below is reproduced from a posting to the BMAA eGroup, where a member helpfully shared this information - which comes from a Rotax expert.

 

First.. the term "cold seizure" is a bit of a misnomer. All seizures are caused by heat/friction. A cold seizure is where the piston expands faster than the bore it is traveling in and contacts the sides of that bore. These are also known as four corner seizures.

 

The worst case scenario is that the engine can just lose power and stop. In the case of a mild (mini) seizure the engine may just lose power for a second or two, but will respond to throttle inputs and will recover when the throttle is advanced. This may happen a few times before a major seizure occurs.

 

Cold seizures "usually" occur after a full throttle run when the engine is powered back to a cruise throttle setting. If the engine has experienced some previous mini seizures, the stoppage can occur anytime in flight as there is already some aluminum (off the piston) attached to the cylinder wall and galling (unwanted removal of aluminum from the piston to the cylinder wall) will be occurring at a variable rate.

 

In a cold seizure scenario the engine may just sputter and lose rpm for a second or two, or it may bring the engine to a complete stop. Once the engine has cooled down a bit it will appear to re-start and run properly. Don't let this fool you. More than one person has tried to fly his plane out of a field where they had to land because the engine quit, only to have the engine fail again in short order.. unfortunately, the second failure usually happens when the pilot has fewer options for a safe off field landing.

 

Don't let "get home itis" bite you.

 

Find out why the engine stopped before you carry on.. After all, the "self fixing engine" has not yet been invented.

 

The cause of the cold seizure can be variable.

 

One obvious one, would be a lack of warm up prior to going to full throttle. Also, long extended descents at low power settings followed by a high power run (go around) can also contribute/cause the problem.

 

A major cold seizure (complete stoppage of the engine) can occur as a result of multiple mini seizures finally causing a big time stoppage of the engine.

 

An easy check for a four corner seizure (cold seizure) on an air cooled engine is to remove the exhaust "Y" pipe (manifold) and take a peek at the sides of the pistons.

 

If the engine has experienced a seizure, the pistons will tell you the story.

 

On a Rotax 582 liquid cooled engine a cold seizure is not usually visible through the exhaust port, and you can not see the piston on the intake port side. You can see a seizure cause by lack of lubrication from the exhaust port.

 

On a cold seizure, there will be vertical scuffing towards to outside edges of the piston as viewed through the exhaust port.

 

There will be two corresponding vertical scuffs on the intake side, but these cannot be viewed without removing the cylinders.. If the engine has experienced a cold seizure these marks will be visible through the exhaust ports.

 

If you have any thoughts that your engine might have experienced a mini through a full seizure, its far cheaper to fix the engine problem than fix both an engine and airframe problem because the engine failed again. The "through the exhaust port" test is simple and definitive!

Cold seizure on Rotax 582 intake side

 

Cold seizure on exhaust side, the only thing that will be seen is the small mark near the center of the piston the outside marks will not be visible.

 

PTO piston has seizure and varnish down below each ring end gap, plus indication of cold seizure on exhaust side of piston.

 

NOTE, that seizure was not viewable via "thru the port inspection", with exception of aluminum deposits on carb side of liner, which would be viewable externally upon close inspection.

 

 

Hy Flyme, love your videos but for god sake, clean your wind screen.

ha ha ha lol

 

 

I would try another prop first!

 

 

confirmedn=...just wish I could get it to run,Im spent with these 447 all 3 of them,any one got somthing else kicking around?

 

 

why?are you after one?

 

 

Belt slip will rob you of thrust at high power settings.. you really have to have them tight.. scary tight!

yeh agree the belts on my robin are super tight.
