people say its dangerous for 9 series rotax to have carbys mounted on top of the engine yet when do you ever hear of any catching fire. about as often as you hear about them back firing.
-
heard of the memphis belle. i will call the xair the taco bell
-
there are lots of 618s around, still a lot flying now. i thought you worked on most aircraft engines. they have 2 different carbys. good for 1000 hrs plus flown by the book . crankshaft breakage probably happened with cold siezure, not a common problem.
-
For the Rotax 618 UL, the main jets typically differ between the PTO and MAG carburetors, with common stock settings being #135 (PTO) and #145 (MAG), though these can change with altitude, intake silencers, or specific setups, with larger jets (like #160/#170) often needed at lower altitudes or with silencers to prevent running too lean, a common issue for this engine. Key Jetting Information Standard/Altitude > 5000ft: #135 (PTO) & #145 (MAG). Sea Level/With Silencer: #160 (PTO) & #170 (MAG). Why Different Sizes? The 618 uses two different carburetors, and they require different fuel flows for optimal performance,

Surprised you haven't heard of that before. It's well known . My egts both run around 600
-
My 618 had the intake silencer box removed. They had to rejet the carbs to allow for the change in restriction. Interesting thing with 618 is the main jets are a different size in each carb.

Any filter can block up. That's called maintenance. When you change or wash them at required intervals.

I only have one alias which is my real name. How does it help safety when you come on here talking crap about 2 mt backfires and saying we are using filters not fit for purpose when they are designed for Rotax and have a part number for each model. Aren't you the same bloke who defended finemores dragging a trailer for 65km with all the tyres blown . Look at yourself before you make up stories about others.
-
i haven't made judgement of you. just pointed out you can be guilty of exactly what you accuse us of. but i do agree things can come across as agressive when that is not the intention, keyboards don't convey emotion very well. i am guilty of pulling your chain, only because you bite so well. i will try and stop doing it. but everything you said about that gyro was wrong. (sorry i slipped back into my old ways😁)

you are the only one that said we use motorbike filters. k&n supplie filters for all rotax aero engines. or K&N air filters suitable for Rotax engines, consider the following options: K&N Universal Air Filters: Available in round, tapered, and oval designs, these filters fit various applications, including Rotax engines. 1 Specific Models: K&N SP 2705 and K&N SP 2703 are designed for the Bing 54 carburetor used on Rotax 503 and 532 engines, respectively. 1 Maintenance: K&N air filters can be cleaned and re-oiled, making them reusable when dirty. 1 Service Tips: Regular servicing is recommended every 6 months or 50 hours of airtime, especially in dirty conditions. 1 For more detailed specifications and purchasing options, you can visit the respective links provided in the results

Crosswind at La Salette (French Alpine grass strip)
BrendAn replied to Garfly's topic in AUS/NZ General Discussion
worked with a shotcrew boss once that had been fifo cairns to the new guinea highlands somewhere. he had been in 24 runway excursions over his time there. touchdown and slide into the bush or off the strip. sometimes a meter of rain a day. -
Can you please post a list of requirements for a post to be satisfactory for you. You are bullying moneybox . There is no need to carry on at him the way you have on this thread. And look at the replies you posted to me yesterday about that gyro. I think you need to man up and apologise for your behaviour.
-
The only input you want to hear is your own. It's ok for you to joke when you feel like it. Take a chill pill
-
Now I am worried I am going to be flying through a sandstorm belching out 2 mt flames.😁
-
K&n filters are good quality as far as I know.
-
You do realise they have layers of cotton between the mesh outer layers.
-
Lucky they are in a clean environment .would you prefer a Donaldson cyclone hanging off the side.🤣
-
Cone air filters are used a lot on Rotax . They would be spark arrestors as well. If your aeroplane is shooting out 2 mt flames you might want to do a tune up😁
-
I needed a high performance endorsement for the red one because red is 10 percent faster than other colours. Look at any Ferrari.
-
its all automatic. you push the stick and off you go. jumpstart gyros have been around for 60 years. not showing off or dangerous. this mculloch had jump start in 1962. very successful machine and sought after even today. and a gust of wind has almost no effect. gyros fly when fw are grounded.
-
They have slightly adjustable rotor pitch. Spin up rotors to 500 rpm at 0 pitch then tilts the rotors 4 degrees for lift off at the same time it disengages the prerotator because you can't have any rotational torque after the wheels leave the ground.
-
It doesn't effect me. I don't have a 912 but I do know people that run them like that with no issues. But maybe there cowls get lots of airflow so temp is not much more than ambient.
-
there are a lot of cowled 912s running cone air filters straight on the carbs with no issues at all. i don't think anyone is saying your wrong but all the engines out there having no issues makes it hard to argue.
-
ela have fixed long take offs.
-
i learn't today that rotax do make airboxs, i always thought that sort of stuff was made to suit .
