Re: X-Air Ultralight Aircraft X Air standard floor replacement
The original is a grey painted plywood. Billy On Monday, August 24, 2015 3:41 PM, "nonobeale@... [X-Air_Ultralight_Aircraft]" wrote:

I recently bought and X air standard. The floor had been replaced with a piece very rough 1/2 inch plywood. What was the material of the original floor and what would be a good replacement material? Thanks for your help.

Re: X-Air Ultralight Aircraft Re: Pitot placement
开云体育I just bought my ex air standard and it has the tube in the nose cone. Seems to work well. It looks like the hollow bolt like you use on a lamp that the electrical cord runs through. On Jul 25, 2015, at 3:55 PM, h.hibbs@... [X-Air_Ultralight_Aircraft] <X-Air_Ultralight_Aircraft@...> wrote:

Re: Radio and antenna - vee rabbit fitting
Johnathan,
Thank you for taking the time to write such a good explanation and include the pictures. I had considered one ages ago but rejected the idea because I thought the included angle between the elements was far less than what I see in your pictures.? This would've meant mounting it more vertically, but where?? I see now that the angle is far less and it is a nice installation. You have inspired me to go and find one, thanks again! Best regards, John B |

Re: X-Air Ultralight Aircraft Re: Radio and antenna - vee rabbit fitting [2 Attachments]
开云体育The switches inside a Lynx intercom need to be set differently for different Icom radio types, and for other manufacturers sets. Are you switches correct? Harry Mendelsonn ( believe I have spelled that correctly?) in Edinburgh, sells Lynx, and has the switch settings somewhere on their website.Cheers, Barbara. 'Jonathan Webb'

Vee Rabbit
mounting
?
?
I mounted
my vee rabbit in much the same way as the old aerial was mounted. It is located
immediately in front of the tail on the fuse tube and held in place by cable
ties with no drilling.
?
My Vee
Rabbit came with an aluminium mounting block designed to sit on a flat surface
while holding the vee upright. I simply drilled 4 holes in the sides of this
block and used 2 very big cable ties. I also used a dremel to round of the base
so it was the same curvature as the fuse tube and I fitted tape over the fuse
tube to protect it. The whole thing will be easy to remove and put back to
original if I want to.
?
?
I'm not
sure how we go about sharing photos on tis group but attached are 2 photos, one
close up showing the mounting block ( not fully tightened when taken and also
before I rounded the base to match the fusetube. ). The other shows the new vee
rabbit temporarily held next to the original aerial using a velcro strap
?
?
There are
supply problems with this particular Vee Rabbit aerial and a rather hot thread
on the South African microlight forum which suggests one should not order it
from or send money too the South African manufacturer.? I got mine from UK
stock. If you can find one in stock I recommend it, otherwise my next
alternative would have been a di-pole. It may well be possible to modify the
dipole into a vee as the vee rabbit fits nicely and looks right mounted on the
back of the fuse tube. It should be noted that it is theoretically not as
efficient as a vertical di pole but mine seems to work very well. When I tested
it my aerodrome gave me readability 5 from 10 miles away.
?
?
One thing I
should point out is the South African Vee Rabbit is very heavy for an antenna.
For me radio is more important than weight as I can easily swap back to the old
one in 15 minutes if I need to.
?
?
With
regards to radios in general. I have had lots of problems with mine which I have
eliminated by using my GA headset directly into the icom with an icom adapter
and a PTT. It seems my Lynx intercom has a problem somewhere as it will receive
but not transmit. Its on my to do list to investigate further.
?

Re: X-Air Ultralight Aircraft Re: Radio and antenna
开云体育You don't need a large disc of aluminium or copper, just one with a radius equal to the length of the whip or vertical element.On 21/07/2015 7:31 PM, 'Jonathan Webb'

Re: Radio and antenna
Hi Ian,
I wouldn't be quick off the mark to blame the antenna, the problem could be caused by several things.? I can say that the antenna is working because you can hear distant traffic. Did the installation work in the days leading up to your landing the other day?? The answer would be good to know to give a datum. Can I suggest finding a Radio Amateur who builds his own equipment (yes, some still do that!) and perhaps he will use his test equipment to find the fault for the price of a beer or a ride in the aircraft. The transmitter was doing it's thing and so was the PTT switch because your signal was heard but lacking the modulation. It seems to me that your microphone signal was not getting to the radio or the microphone signal processing section of the radio is not working.? Some radios are very sensitive to DC volts being lower than it should be so as someone said earlier, check that and include the return path or negative lead back to the battery.? Look at the microphone path first for cable damage or other obvious things like the headset plugged into the wrong side of a 2-place intercom box - yes, I did that too! Johnathan, Would you describe how your Vee Rabbit has been mounted to your aircraft please? John B |

Re: Radio and antenna
All good suggestions Jackye, Barbara and Seamus. Thanks for the info Jonathan, I'll take a look at that antenna.
So, in answer to some suggestions, not in any particular order:- I have a spare headset, so I'll try that and check the PTT. I
have 2 headset connectors, but just my DC plugged in. ?My headset
connectors are insulated and I only have a single ground for everything,
so I'll also check the integrity of the ground and the cable for the
antenna. The
Airkit anetnna doesn't have a ground plane as such and I think that
this was Michael's issue with it. ?He said, and I'm quoting from a
fallible memory here, that the SWR was not good, hence my comment in the
first post. Details of the antenna here -? As
I said I'm only at the beginning of this little problem, so next time
I'm around other flyers I'll try the transmit test from both headsets,
both sockets and both PTTs and report back, but thanks for the all
input. Can
I just add, for the record, that I'm very happy with the Jab on my
X-Air. I know that they've been getting a lot of bad press lately, but
you never hear from people who just fly behind a Jab and are happy.
Sure, every engine has it's weak points, Rotax has around 70 hose
connectors to go wrong, for example. There's no such thing as the
perfect engine, but all manufacturers try to get as near to it as they
can. ?Some are more successful that others. ?Doesn't mean they produce a
bad engine! Just sayin............. Ian Sorry if I've just posted a number of blank replies, as using this group with Safari on my iPad seems to go nuts.? Is it just me?? To post this I had to stoke up my desktop.? WTF!!!! |

Re: Radio and antenna
开云体育In the year I have owned my X-air Falcon , I have also had poor radio
problems.? Cleaning the antenna earth helped but reception was never
perfect.
?
I have now solved the problem permanently by fitting a Vee Rabbit antenna
-
?
?
Reception is now perfect, probably as good or better than the certified kit
in my Cessna.
?
?
I'm not a radio expert but I believe that a rag and tube aircraft like ours
is not a perfect ground plan for antennas. The Vee Rabbit solves this problem
because it needs no ground plane, one half of the vee performs that
function.
?
?
The linked Vee Rabbit antenna is hard to get hold of but if it was not
available I would just buy a dipole and find someway of fitting it.
?
Alternatively you could try improving the ground plane with a large disc of
aluminium or copper under your existing antenna.
?
?
It pays to do a lot of googleing. Radios and radio waves are funny things.
They are even sensitive to exactly how long the antenna cable is ( t should be
in particular multiples of the radio wave ) If your on a tight budget you can
also build your own vee rabbit aerial for next to nothing. There are
instructions online.

Long range tanks - X air Falcon
开云体育I Notice there are long range tanks available for the X-air falcon
?
?
?
How are these mounted to the aircraft? I see it sits on the fuse tube but
was wondering how it was attached and if it is easy to add and remove.
?
The reason is in the UK we would not be allowed to permanently fit such a
thing due to weight but I was toying with using one on a temporary basis for
long distance solo? flying trips away and then removing it at the end of
each trip.
?
Is that practical? or is it a whole load of work to fit in.
?
How do they plumb into the fuel system? Its it just a tube down into the
tank with a fuel tap and just reliant on gravity ?
?
?
?
Regards,
?
Jonathan

PS “Is this list still alive “ – yes, its very much alive. Not sure about
others but I haven't broken anything for ages so have had no reason to post.
X-airs are very reliable and easy to fix which results in much lower levels of
forum posts. If? you want a very active forum, buy a Jabiru ;o)? I
looked at Jabs when buying but I'm sooooo glad I bought a 912 Xair Falcon. I
recently spent a week flying touring in eastern England, camping under the
wing.... faaaantastic. I'm planning another week away just as soon as its tops
raining :o)

Hi Ian
?
any bit of wire will allow you to receive, transmitting is
a different ball game, the biggest problems I have found is
antenna?grounding issues.
?
Are you able to transmit while on the ground to say a
handheld? if not then it is probably nothing to do with the antenna unless the
cable is damaged or bnc not connecting properly. You could have a transmitter or
intercom interface problem.
?
Normally antenna related problems are identified by
working ok on the ground but not good in air or short range.
