Re: X-air H and 912uls


 

Thanks Michael, some really good info to work with. The problem is that there isn't any real decent alternatives to keep them flying. They are fairly high drag/low speed which is where the issues start with aircooled configurations. I'm just not ready to give up on the little kite just yet, absolutely loved flying it and did a number of trips around 650km in a day.

The Dalby guys are good LAME's so will keep working at it when I get the time and see where it goes.

Thanks again for your info.

Cheers
Greg

Hello Greg and others. I didn't see a lot of standard model X-Air's in France fitted with the 912 which we used to tow huge advertising banners along the French coastline. These worked really well with the 912 because the banner created so much drag it balanced the aircraft. The 912? is definitely heavier than the Jabiru by the time you add all of the extras like the exhaust system, the oil tank etc. the 912 versions in France basically had the very rear of the engine touching the leading edge of the wing, they sat back a real long way and if they weren't towing a banner they required a lot of back stick just to fly straight and level this is why I just wouldn't recommend the 912. Added to this is the fact that you need to store the oil reservoir inside the wing above the cockpit and this comes with its own problems when it comes time to change the oil etc...?? you will need to cut a hole in the wing nappy because the oil tank is too large to fit through the wing without opening the top. Also, the oil tank needs to sit above the main fuselage tube because most of them there is not enough room between the large wing ribs at the end of each wing and the fuselage tube to fit the oil tank.....

Hi, if you are meaning the original xair std that mostly had the 2 stroke engines on them thenI have tried to find the mount you are referring to (shown in the xair std manual as option) however no luck. I did ask Michael a good while ago and was informed they were never put into production. I also chased up Seamus in Ireland, wealth of knowledge but a difficult guy to contact at times, guess like us all very little spare time.

I don't agree with the too heavy statement, they are similar in weight to a Jabiru 2200 which I have on mine from first flight,? it balanced well in the middle range for the weight and balance calculations and flies very nicely. I have flown it for some quite long distances and it performs and handles very well and never any real trim needed.

However the Jabiru suffers with temp issues and after many years and 300hrs of flying trying different duct shapes came to the conclusion that the airspeed for the cruise rpm is just not sufficient.

I have been working with my local LAME and they are confident that they can modify a 912 rear mount onto the Jabiru mount.

The original Jabiru mount was supplied by Jabiru in Bunderburg.

At the moment I don't have much more I can give you as I haven't started on the mod, hopefully this is the year to get it done.

Cheers
Greg

Hello, your messages a bit confusing because in the subject you are referring to the Hanuman model but in the text body you are referring to the X-Air standard ?

The 912 is really too heavy for the standard model, requires a lot of modifications and really doesn't fly any good with such a heavy engine. You are much better off only using the 912 in the Hanuman model.
