Re: New X-air H Hanuman owner
If the Jab is not properly cooled, it will destroy itself quite quickly. It really needs two temp guahes, and initially, constant temperature checks. Mo.

? Hi All, Greetings from the US.? I recently purchased my first plane, a 2007 X-air H. I am in the process of bringing it up to snuff, but resources for the plane are scant here. There is a fair amount of clean up and I think the prop that's on it is wrong, but I need to do a bit more digging on that. The little Jabiru may not be breathing well. I'm sure I'll be posting about that shortly :)
The biggest problem I'm having is that of aileron control. Specifically, when flying above about 66kts the plane is less stable than I feel it should be, tossing to the side off and on. At or below 65kts it will fly hands-off, but getting up to about 70kts or more, it requires constant vigilance and substantial correction any time the wind blows it even a tiny bit.
Otherwise, the plane feels great, with good, tight rudder response and gentle characteristics.?
I feel like this is abnormal for this plane, based on what I've read, but I've never flown any others.?
Can anyone offer any insight or suggestions as to what to check or adjust? Are there any other resources online you guys can point me towards to help me along my journey?
I'm sure I'll have lots of questions, and I appreciate everyone's help.

Re: New X-air H Hanuman owner
I believe it is overpropped. It seems like around 60x38 is more the norm. But I want to double-check the engine and make sure it is getting everything it needs to make good power before I spend a bunch on a propeller.

Re: New X-air H Hanuman owner
I'm new to my x Air Hawk as well but I have a Sensenich ground adjustable prop and it is incredible. Super easy to change pitch and it has 5 different increments to cater to your specific needs.
Make sure both mags and sets of plugs are operating as they should.
Obviously check fuel supply/system, with and without electronic boost pump. Make sure mechanical pump is not leaking, subsequently loosing vacuum by introducing air.
Verify correct oil viscosity and quantity inside crankcase.
Set up auxiliary tachometer to test that your primary tach is working as it should - if different equipment is giving different readings, then you can start to omit potential culprits through process of elimination.
May you elaborate more on your air intake setup? Pictures would help. What does the modification consist of and what was the intent to modify in the first place?

Thank you all for your help and insight.
To summarize, The consensus is there is possibly an issue with the flaps (I'm thinking possibly the right one because it banks to the left), Ailerons might not be set right, or there is some slop in the control cables.
There is a big ice storm here in Indiana for the next couple of days, so I can't get to the hanger, but will start working through this shortly. I trailered it home, so I have to put the wings back on and double-check the controls anyway. Does anyone have
any suggestions for how to go about checking the rigging? I know, follow the manual, but I didn't know if there was any experience or tricks that might help.
As for my issue with the Jab 2200. It's unable to make it over 2700rpm on the ground, and 2800-2900 at best in the air. Take-off roll was around 300m on a day with an air density altitude of -1500ft. Climb with about 900lbs load was around 500fpm. So I figure
it's barely making 75% power; that could be an issue. :P?
I think the gentleman I got it from had too large and/or too much pitch in the prop, (64x34 I think) but I'm not 100% sure. Engine compressions are good, with leak downs being 74/80 76/80 72/80 74/80. The air breather assembly he made is possibly causing
some restriction. Any recommendations for a prop if I can't get it going right?
Thanks again. You guys have already been super helpful!

Re: New X-air H Hanuman owner
Hi You should have at least 2800 rpm on ground if not there is to much pitch on prop. Ground run longer but higher speed. What kind of prop do you have? Ground adjustable pitch prop or fixed? I have Sensenich ground adjustable propeller and works fine. regards ----- Upprunalegt skeyti ----- Frá: kymidnight@...

Re: New X-air H Hanuman owner
Hi All, Greetings from the US.? I recently purchased my first
plane, a 2007 X-air H. I am in the process of bringing it up to
snuff, but resources for the plane are scant here. There is a
fair amount of clean up and I think the prop that's on it is
wrong, but I need to do a bit more digging on that. The little
Jabiru may not be breathing well. I'm sure I'll be posting about
that shortly :)??? unfortunately the
Jabiru just doesn't perform as the same horsepower Rotax
engine. If you are trying to compare the 2 side-by-side you
will be disappointed. Just follow the performance information
and specifications in the Jabiru manual and tweak the aircraft
to perform as best as it can
The biggest problem I'm having is that of aileron control.
Specifically, when flying above about 66kts the plane is less
stable than I feel it should be, tossing to the side off and on.
At or below 65kts it will fly hands-off, but getting up to about
70kts or more, it requires constant vigilance and substantial
correction any time the wind blows it even a tiny bit.??? sounds like a combination of the aileron and
the flaps are not set correctly or you have free play in the
controls.....?? Free play in the controls will do exactly as
you describe
Otherwise, the plane feels great, with good, tight rudder
response and gentle characteristics.?
I feel like this is abnormal for this plane, based on what
I've read, but I've never flown any others.?
Can anyone offer any insight or suggestions as to what to
check or adjust? Are there any other resources online you guys
can point me towards to help me along my journey???? it does sound like your aircraft is flying
differently to many of the others that are out there so I
would strongly recommend checking all of the rigging? for the
aileron and flight controls as per the assembly manual
I'm sure I'll have lots of questions, and I appreciate
everyone's help.

I had an issue in my XAir H where the aircraft wanted to do a slight turn during cruise. Thought as well might be a rigging issue but why suddenly?
Turns out the problem and fix was simple. The port flap was not fully retracted due to minor interference from a cotter pin. Once that was rectified, problem solved!

Re: New X-air H Hanuman owner
One additional item to check. How is the rudder trim. Mine when I first bought it had a slight turning tendency (can't remember which way). I added a fixed trim tab to the rudder and that solved the problem after some trial and error adjustment.

Re: X-Air LS (H Model) Replacement Tires
I was thinking about the?480/400 x 8 / 7012?Tire & Tube Kit from Aircraft Spruce model 7012. Only $35 a set. They are about .4" wider than stock, but otherwise seem about perfect. They also have a sawtooth tread pattern if you like that.??
