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.
