Hello Michael, the best way is to do with exactly the same as it is supplied originally by Rotax, that way you know everything works

Hi,

I bought a 2nd hand 618 xair quiet a few years ago that had the oil injection removed because the previous owner reckoned he had some problems with it. I have been premixing the fuel and had no problems but I have now just purchased new oil injection parts from Floods and I'm about to put it on.

I can't see any reason there should be problems with oil injection at all I'm looking forward to getting it installed.

Like Michael said a gazillion boats and other craft have been using it for years.

My question is there any resources available here with the best way to install the oil injection system and mounting locations for everything?

I would appreciate any help.

Cheers

Michael Tyler.

Please make sure it is UV rated polycarbonate. The stuff you will get from a hardware store may only last 6 months if it spends a few days out in the sun. If it is not UV rated it very quickly gets damaged and becomes brittle. Make sure it has UV rated or "this side to the sun" printed on the plastic protection sheet. Thanks Michael

I've just replaced one windshield and one door on my Xair Falcon.

I used Lexan which is a top brand of Polycarbonate Sheet.

https://www.theplasticshop.co.uk/polycarbonate-sheet-2mm-3mm-4mm-5mm-6mm-8mm-thick.html

I was advised to use 1.5mm as its easier to cut. Having bought it I found the original on my aircraft was 2mm. My windscreen is in 2 halves and I have only replaced one half. In the air I notice the 1.5mm deforms more than the 2mm and it wobbles a bit on full power.

Its not a big issue but if I was ordering again I think I would stay with 2mm for the windscreen. On the doors it makes no difference and 1.5mm is fine.

I cut it using tin snips with a dremel on the dv port on the door window. I had no problems cutting it.

Don't use a jigsaw as it will split. When drilling screw holes make them large enough to allow for any expansion or movement. If they are tight the Lexan may crack around screws.

Jonathan

I have a Hanuman/Hawk with a Jabiru 2200 engine on it. Not being its first owner, I ran into a problem, specifically, one of the previous owners had lost the intake airbox and replaced it with a section of scat hose which was then run to a filter. This worked fine for several years, but as the hose has aged, it has become problematic.

Doing some looking online, I realized that the factory designed an airbox that fits in the tiny space between the carb and the firewall, that I did not have. I know that the best solution would be to purchase an airbox from the factory, however, I have not been able to get a response from them for several years. As such, I took it upon myself to address the issue and designed and 3d printed an airbox and intake pipe for the plane. I then printed it in a high-grade engineering nylon. So far, it seems pretty good; it's very light too.

Obviously, this falls squarely in the territory of experimental aviation, but it occurred to me that I might not be the only person who had this problem or could use this, so I published the files on thingiverse for anyone to use.

Re: X-air Standard with rotax 618 engine

mcoates@... (Michael Coates) — Mon, 03 Jun 2024 15:53:17 -0700

Hello, we ran the 618 engine for years and years basically without any problems. If you let them warm up properly before you go hurtling down the runway they seem to last forever. Every 200 or 300 hours the power valve would need cleaning because of carbon deposits but this only took about 10 minutes to complete so it was a nonevent. All of the ones that we sold had the oil injection and never gave any problem provided you kept oil in the tank. There is much more chance of a person forgetting to mix oil into the fuel properly than the oil pump to stop working. Just look at all of the millions of outboards with oil injection going for 100 years without any problems.

The only time we found problems with 2 strokes was when people started to play with them, change the jetting, change the air cleaners or do other things to get better performance, better fuel economy and everything else they perceived they could fix/repair. If you kept them totally standard they would work perfectly. If you started to play because you thought you could do things better than Rotax then it started to cause difficulties for the engines.

The biggest advice I give anybody is to make sure the engine is completely heat so before you go flying, my recommendation was to warm the engine up, jump out and go for a pee or whatever else you needed to do and then jump back in and go flying. This gave a chance for the heat to go through the entire engine and warm everything up properly, this is the best advice I can give for a long engine life. Many thanks Michael

[email protected]"> Hey All. Recently I purchased an x-air Standard with a rotax 618 engine. I just wanted to ask, I’ve heard different stories about their reliability as opposed to the 582 engines that are common on these aircraft. I’ve heard that the 582 is fairly reliable. But I’ve heard differing opinions on the 618 engine. I know mine does not have a cylinder head temperature gauge, but does have a exhaust temperature gauge. The aircraft and engine only have 82 hours on them, however the whole thing is 24 years old. And at this time, I do not have the money or time to have the engine overhauled. So I would like to run on condition if possible. I believe this should be okay. But I just want to know if anybody else owns a similar aircraft and engine combination, if there are any problems I need to watch out for. I don’t use the oil injector, the person I bought the aircraft OFF removed it and told me I should premix the fuel. He also said it was a 50 to one ratio. So 200 mL for every 10 L of fuel. Although he told me to bump it up to 220 mL , for a little bit of extra protection. I did have the engine running once, but didn’t have it running very long. It sounded okay, and ran fine at idle and at reasonable rpm. But didn’t open it up to full power. Some people have told me that they need to be run wide-open. Others have told me that they can run to lean while climbing out and that causes them to burn out. I just would like to know the information about the engine and how to make it last as long as possible. I know of many people who have had 582s running on condition for over 1000 hours with great success. Hopefully the 618 can be just as reliable if you look after it right. Any information would be greatly appreciated. Also, in general, any general things to look out for with the aircraft in general. As this is my first time owning an x-air. I have heard that they are extremely low maintenance. But anything to watch out For or anything that I should do to make the aircraft last as long as possible would be greatly appreciated.
