engine missing, check and clean micro filter inside fuel pump if there is one, also do a fuel pressure test, filters may be blocked, it is fuel starvation will happen on full throttle with a backfire. I had similar with rotax 914 and every one i spoke too thought there was fuel contamination. Checked pump one and found the microfilter blocked could not see daylight after 100hrs from new, after cleaning problem solved.

 

 

Went for a fly to Inverloch, Venus Bay and on the way back over wonthaggi, was just before xmas 2014 some office staff were at Venus bay enjoying the surf and collecting shellfish (pipies). Couple of runs up Venus bay beach and could count 5 rips. Did a couple of dives to take a closer look and some of the pipie collecters were not far from one of those rips. Unfortunately one of the swimmers got caught up in the rips and drowned.

 

Low flying with the gyro is fantastic dogging the beach goers and the surf. Compiled a dash cam video and it rus for 18mins, did chop a lot but guess a lot of roller coaster turns would go if take off more, here it is;

BRP introduces a more powerful 135-hp Rotax aircraft engine at the EAA AirVenture in Oshkosh, Wisconsin – the Rotax 915 iS.

 

 

Oshkosh / Wisconsin, U.S.A., July 21, 2015 – BRP introduces a more powerful 135-hp Rotax aircraft engine at the EAA AirVenture in Oshkosh, Wisconsin – the Rotax 915 iS.

 

Based on the proven concept of the Rotax 912 / 914 engine series, the Rotax 915 iS engine offers more power, the best power-to-weight ratio in its class and full take-off power up to at least 15,000 feet (4,570 m) with a service ceiling of 23,000 feet (7,010 m).

 

“This more powerful aircraft engine – the Rotax 915 iS – was specifically requested by our customers. It opens the market to larger, heavier aircraft, larger gyrocopters and even small helicopters, or simply more performance for current applications,” said Thomas Uhr, vice president BRP-Powertrain and general manager BRP-Powertrain GmbH & Co KG. “BRP’s Rotax 4-stroke aircraft engines are already industry leaders; opening other markets represents a good growth opportunity.”

 

The introduction of the Rotax 915 iS engine, a 4-stroke, 4-cylinder turbocharged aircraft engine with intercooler and a redundant fuel injection system, is in response to market demand for a modern, more powerful engine allowing higher payload and shorter take-offs. It delivers the most advanced aircraft engine technology resulting in low operating cost and ease of use. The serial production of the Rotax 915 iS engine is scheduled for second half of 2017.

Brendan, 20hrs duel and 5 hrs solo is correct, but good luck if you would be allowed to go solo after 20hrs (Recreational choppers only). Turbines is a different endorsement including theory.

 

 

like what others have said try a thread chaser, if using helicoil you need to pick up all the metal that falls into the bore, have done it in the past and used a flexible pen light and double sided tape on a long thin screw driver to pick the bits of metal.

 

 

There is no duty on aircrafts or aircraft parts, but 10% GST applies to cost of goods and freight converted in AUD. Once the weight goes over 50kg the cost goes up, $98 to $105 per cubic mtr if in box just for a forlift driver to unload from an LCL container if ocean freight. Airfreight is different again, charges vary. If you bring an engine with a declaration from supplier stating warranty repair, there are no gst charges, may have to pay $70 brokerage fee for the customs and AQIS lodgements.

 

 

My small piece of advice is no matter what else you do, use an Australian based import agent. Overseas agents will be cheaper on paper but there is a reason for that.

sorry, trying to understand what you are saying or have i missed something. You mean customs broker right, they have to be licensed in Australia or they cannot handle your cargo (you cannot use an overseas agent unless you want to travel, different story). Usually a customs broker here will contact their nominated broker in the country of origin. I have between 10 to 15 containers every month from Asia, US and EU, using 2 brokers to keep them honest, this is my business i ought to know the traps, unfortunately i do not advice, i provide the facts in the real world.

 

 

Hi Mark, welcome, Mozambique is an awesome place to have a bit of fun, many of you south africans fly gyro`s have been speaking to the agent for arrow in SA and these guys have a coastal gyro flying tour each year to Namibia. Way out of my reach unless i can tee up an overseas trip.

 

 

ok here are some of the issues you will encounter, if on a pallet you will need an SP15 certification from an authorised body (the wood need to be heat treated by a licensed cargo handler) you will need a declaration from the rebuilder stating that the engine is clean and free from dirt, grit, soil etc.

 

It depends on the size of engine, you can try interparcel (i brought a hirth back from germany was $700 aud all up foamed up in a cardboard box no wood 38kg), you will need the dimensions and weight to get a quote or you can use a broker.

 

If you like a broker " priority cargo " speak with Dora 0290911111 mention Carl from AJ Australia they import from any where in the world, they have just brought in aircraft parts from France.

 

 

The Android is a clone, if you leave apple you will regret. There are many bugs that get picked up in the android system , just turfed my samsung in the S bend and flushed, 8 months of headache is enough. Have 4 of my staff crush theirs, i have got them back to apple.

 

My suppliers overseas are also changing back to apple after a painful experience.

 

 

very nice plane, insurance may be an issue, i am sure there is a question on carbon fibre hulls due to toxicity ie; cleaning up on a crash.

 

 

Thought will bring this subject up after purchasing a new box (12 x 1ltr) of aero shell sport plus4 oil. I had a release certificate and an expiry date, also on each red bottle (previous black with orange label). Called an expert in the oil industry and he said it is to do with the the antifoaming additives going off within a period of 4yrs from date of manufacture. The release document i received stated "this document is issued under the authority of joint fuels and lubricants agency, department of defence.

 

My point here is that the use by date from date of manufacture needs to be checked to ensure the oil is good for use.

 

 

mine is an ipad 4 mini wifi ios 8.3 no issues so far, but is a worry if has disconnected, better program the 695 incase.

 

 

The mixture screw as it is commonly called is actually the idle air mixture screw and it controls the amount of air (not fuel) in the idle circuit, so screwing it in for less air richens the mix, screw it out for more air an leaner mix.This only affects the idle circuit. When the butterfly opens up a bit there is not enough vacuum through the idle circuit an the job is taken over by the midrange circuit, the needle jet and jet needle, then once the jet needle is withdrawn enough the full throttle mixture is controlled by the main jet.

So moving the idle mixture screw will affect your idling but not your cruise speed.

 

I think just covering a portion of your radiator with some duct tape will raise the temps a bit and easy to go back or you could try a fitting a coolant thermostat, see John Gilpins Stolspeed site for an in depth investigation into fitting a thermostat.

 

Hope this in someway helps.

 

Cheers

Thanks Rick, you are correct it is the air mixture screw turning in has to effect the idle cutting the air mixture, hence turning out must lean same as the bing carbies on the 582.

 

 

[MAP][/MAP]There are people here better able to explain it than me but I believe what I've said to be correct.The capacitor is a recomended option by Rotax. Some people do not fit it.

http://pointsforpilots.blogspot.com.au/2012/12/testing-rotax-912914-generator-and.html

Here is the rectifier connection drawings i received from Bert Flood when doing my wiring, if the 22mf 25v capacitor was an option why is it on the drawing, and why was i told that it must be added.

What are you looking for after you lean the mixture IE what is the problem with the setting at the momentAs has been mentioned in the earlier posts the only way to check mixture by looking at the plugs is to shut both mags off after a sustained high speed run which is not possible

even taxing for a few minutes will cause black plugs on two cylinders

 

and if two cylinders are running rich and you back the mixture off the other two cylinders will run lean

Engine is running cold on CHT, 3-4 cyl showing black soot. Cyl 1-2 just ok but still too dark grey for my liking.

 

 

I run my 912 uls at 1 turn as do a few people in my area.Black plugs are pretty normal after idling the engine. The only sure way to read the plugs is to immediately shut it down after a high rev run.( which I've not done)

I was concerned like you are with the plugs but was told it's normal as long as it runs fine in flight and sensors read normal.

 

They are tuned to run at 5000 to 5500.....and love doing so.....

Thanks for that have now set mixture to 1 x turn, lets see what happens this weekend

 

 

The regulator disperses extra capacity as heat, not the capacitor.The capacitor smoothes out the voltage spikes coming from the generator to the regulator I believe, protecting the regulator.

A failed capacitor is much cheaper to replace than a regulator.

 

The Rotax 25v capacitor is very marginal. Most "in the know" use a 40v one as spikes from the generator can be well over 25v.

 

I have had a 25v capacitor fail and replaced this with a 40v one.

 

Thanks to those on this forum for their advice on that matter.......

The regulator/rectifier has a series of diodes and resistors (hence called a voltage converter) where does the extra current go if the capacitor does not take up the load and discharge the excess!! If you do not have a capacitor connected to second positive (lead heading to the battery) the rectifier will heat up until one day you will end up with an open circuit. If no capacitor connected to `G`positive and say you have a loose ignition connection or you inadvertently turn `C` positive which is your ignition before shutting the mags you will cook the regulator in about 2-3 attempts.

 

 

i had a low oil pressure reading on my 914 found out that is was a loose wire to the pressure sensor connector.

 

 

Rotax says 1.5turns out on mixture screw from fully in, but cylinder 3 and 4 always seem to be running rich (plugs have black soot 3 and 4). Has anyone tried 1 x turn out on mixture screw from fully in. Also engine temp does not go into green stays just below, but in summer some times gets into the lower end of the green area on rotax engine temp gauge.

 

Oil temp always stays in the green, so no issue there.

 

 

minimum height for gyro 300ft, need endorsement to fly above 500ft, opposite to fixed wing.

 

 

Your rectifier has 2 x positives, 1 x goes to your ignition and the other to your battery. You may need to connect a 25mp capacitor to discharge the excess current generated or matter of time the rectifier will fail, it happened to me.

 

 

I always have an andrenaline rush when i fly my cavalon, easter sunday flew from Tyabb to Rushworth. The weather was not the best visibility to VFR route via Kilmore gap was bad and checked into a friends property in Berwick Vic. After half hour realised an openning in the clouds and set off again via hurtsbridge on VFR route to Kilmore gap. Although i have a Garmin 695 i rarely use it, OZ runways on my mini ipad is fantastic for all information including weather. After the Kilmore gap tracking NW to the waranga dam and then SE to Rushworth. There i met up with a number of other ultralight flyers and was bloody windy hence they werent game to be up in the air. Late afternoon i decided to head back to Tyabb, but before i wanted to give the property owner some experience in a gyro, the camera was a cheapy that i removed from dash cam and inserted it onto my gyro wind shield, not much editing and left the sound as is, here is the link:

When i got back i could not get the property owner to shut up, nor could i wipe the smile from his face as you would realise from the podcast.

 

Thought i post this to show the versatility of a gyro.

 

 

The rotaxowner.com courses in the US are fantastic, there are several levels of competency for rotax 2 stroke 582 to 912-914 series. Well worth the trip and well managed courses.

 

 

Welcome Carl. That's an impressive looking chariot. Good visibility colour. Nev

Thanks mate, it is a good tourer for 2 pilots
