  1. We push it out, turn 90degrees away from hangar before starting it. After flying stop again 90degrees to hangar opening, turn it around and push back in. Guess you could nose or tail in, we’ve always done it this way.

    The hangar is augered into the ground So, in theory, isn’t a permanent structure. This is in case the councils ever start getting involved. The front is the door which rolls with a winder. There are guide poles that can be seen in photo that are removable.

    they are from David Gill hothouses in Bagshot, Vic. Not expensive, and can be different sizes. Mines 6m deep and 10m wide.

    good luck,

    I have over 5,000 hours behind Jabiru 2200 engines.

     

    This most recent Jab is the Generation 4. On this version Jab improved the top end which allows closer tolerances so that I don't have to add any oil between oil changes at 30 hours.

     

    The engine is much simpler design that fits easily into my Avid MK4.

    The earlier engines had issues with valves, valve guides and separated valve heads.

    As mentioned the top end has been completely redesigned including better lubrication of the rocker box.

    That said, the Rotax engines do have some advantages which can also be a disadvantage.

    The gear box allows longer props, but the gear box is one of the problem parts. The engine sound is different since it typically is running at twice the room of the Jabs.

    The engine is about 20 pounds heavier which eats up some of that extra hp.

    Yes, parts are much more expensive.

    Two carbs have to be synced properly.

    I mix gas types with no issues and run my 2200 on ARCO premium 91 AKI. The higher compression of the Rotax may not allow this octane level. Although I have noticed that some do run mogas.

    The Rotax engine is well built and runs a long time between overhauls. It's the gear box and Sprauge clutch that need more frequent servicing.

    I fly a lot and already have 160 hours on my new Jab gen 4 engine.

    The only issues I have had is Starter Bendix unit. Jabiru changed from the reliable Honda Bendix to a brand the only lasts for 50 hours in my experience.

    I am in contact with Jab in encouraging a change back to the Honda brand.

    My engine burns 2.8 gph at above 7500 MSL when I lean it out.

    I am counting on this engine to take me to the day when due to age I'll have to hang up my headset for good. I'm 83 so I still have a few years to enjoy flight.

    Thank you, John.

    theres a lot more to choosing a new plane than I ever thought!

  3. You’re right Scott, am looking at the Bushcat which I guess will be quite draggy as it’s a very wide fuselage and sailcloth wings. But it’s more that I’m looking at a totally different aircraft and want to be sure that I’m not creating headaches for myself.

    Cheers

  4. Thank you Downunder,

    you have answered all my questions. Seems many smaller aircraft do fit the Rotax 912 as standard, and don’t hear of too many issues. My husband says it’s a more modern type engine than the Jab, mare technical, as you say, bit more like a motorbike engine.

    Cheers

  5. Sure, currently have Jabiru LSA, 850 engine hours, do approx 30 hours per year, but would be doing more if I could take my husband away with me. Currently can’t take pax, fuel and luggage.

    Am thinking of a nose wheel Bushcat for all those reasons. But they only have the option of a Rotax engine.

    also, I only have a hangar 6m x 10m so whatever I get need to fit in it. ?

  6. I was wondering about people’s ideas on both the above engines.

    Thinking about a new aircraft but it has the Rotax 912uls in it. I’ve currently got a Jabiru 2200 80hp. The Jab engine has been extremely reliable and easy to work on. Theres plenty of room around it and most things are easy to get at for the minor servicing. It only uses 13 litres per hour, but I’ve always used avgas. You can use unleaded but fuel types can’t be mixed. Cruises at 90kts. The Rotax is heavier on fuel, around 17 litres per hour, but I’ve been told they run better on unleaded, and the fuel can be mixed if necessary. The engine seems considerably more complicated, and takes ap much more room, which I’m guessing makes it more difficult to do routine servicing. From what I’ve a heard parts also seem more expensive, so I guess annuals would be too. Also heard they are hard to start in colder weather? Does anyone know if the power is as good as the Jab (80hp v 100hp)? The Rotax cruises at around 80kts. Are they as reliable?

    Just interested to know others thoughts ...

  7. Hi,

    I own a Jabiru LSA, empty weight of 270kg and with max weight of 430k. It doesnt give much to play with.

    So I can put 2 average people in, min fuel and taxi round a bit, or a lightweight pax and enough fuel for joyflight, or by myself with 65 litres and overnight bag.

    We have enquired about increasing the weight limit to 470kg, but were told that there wouldn't be any weight increases available on these older models. So we play with what we've got!

    Hope this helps

    Hi FBB,

    out of interest, did you live in Qld and fly hang gliders? I used to know a FB from there.

    enjoy your flying.
