Over here there is a product called Aerothane 100 by Polyfiber (www.polyfiber.com) which is a UV clearcoat. A lot of manufacturers in the US now offer this as an option, mostly for cenonite coverings but it works just as well on Dacron. Aparently Dupont makes something similar but I don't have the exact name of it. Guy De France at Speedwing uses it (Dupont stuff) and has very good results. Aerothane works very well but if you regularly play with the fabric (ie: open the fastback) it cracks and you run the chance of the cracks acting like a knife on the rest of the fabric. I was going to cover mine but since I keep it in an excellent hangar there is no need for the UV. Keeping stains off on the other hand is another topic altogether. My leading edge is grey and while is has some stains from fuel and such its not too obvious so I'm not very worried.

G'day everyone, Just to let everyone know what we're going to be doing: On July 17, 2000, the Musarra Family will embark on a 6 month journey around Australia. Our goal: to circumnavigate the continent of Australia in an ultralight aircraft. Larry and Aren Musarra will fly the ultralight, while the rest of the family, Lenne', Sungie, and Tim, take the low road, following the route in a motor home. There's a link to our web page on the egroups link area, or you can link to it at http://www.flyabout.net/

Australian's seem to be a fairly big lot of people, a lot of our customers, my-self included are well over 180cm (6 feet) tall. The legroom in the X-Air is ample for most people but some need the extra room and we have been sucessfully 'stretching' the X-Air for several people. Firstly, using the standard floor as a template we make the floor 100mm longer towards the front of the aircraft, all the holes etc are drilled as normal and the wood (12mm marine ply) is sealed and painted. I make another two holes directly in line with the existing bolt holes for the pedals exactly 75mm forward of their excisting positions. You cannot go any further forward without the rudder pedals contacting the pod at full lock. The bolts which would go through the normal pedal position are now too long, so disgard them and purchase the correct length and grade, you will also need two more new bolts to hold the pedals in the new position. The adjustable arms which attach from the normal rudder pedal position to the front steering yoke for the front wheel will also need to be shortened by exactly 75mm and the rudder cables will need to be lengthened 75mm, i have attached a picture of the extensions which we use for the rudder cables, they are stainless steel and are rated at over 2.5 tonnes (so they are strong enough). If your adding carpet to your floor use a good quality marine carpet as they wont rot, they are close weave and therefore resist dirt etc, they are easy to vacumn and designed to be washed down with water when it gets dirty. Attach the carpet with contact adhesive to the floor and use a soldering iron to burn the bolt holes through the carpet, this seals each hole and will make it much easier to pass all the bolts through, mount all the controls etc over the top of the carpet and this will help the glue hold everything in place as the different parts are bolted to the floor. Hope this helps Best Wishes, Michael Coates Sydney, Australia. Home of the 2000 Olympics Email mcoates@...

Some owners have mentioned the fuel vent tubes are able to bend over and crimp, possibly stopping the fuel supply because it can cause a vacumn in the tanks. We have 'discovered' another idea which works really well and it involves putting a piece of heavy duty fuel tube inside the existing clear tubing, this way the tube will make the bend without crimping, we also have tried a couple of plastic 90 degree bends from water irrigation systems but they are a lot more mucking around. The Brit's have just started using a coiled wire, wrap some stiff wire around a small tube several times, remove the breather and insert the wire on the bend, so far it works but i worry about the chances of rust etc... a couple of years down the track.

We have just posted some pictures of a Rotax 912 powered X-Air in the 'Files' section of this site. There are plenty of close-ups of the modified engine mounts and i am told she flies really well. Look for the photographs in the Rotax 912 folder Thanks Michael

Hi I am Darrel Peatey the Xair dealer for Tasmania I would like to hear from other people with similar interests.

Anyone got true performance figures to compare the 618, 912 and the Jabiru 2.2? We had a Thruster T500 at our airfield that had a 912 mounted. It seemed to work OK (I flew in it), however I couldn\'t help think the advantages of the bigger motor/prop may have been negated somewhat by the drag/weight increase. Ofcourse, no one can dispute the 912 reliability though, which is a big bonus.

Hi, I'm Bill Magrini -- Xair Dealer in the US fort Virginia and Maryland. I just completed my Xair F and have flown it twice. I Didn't set the prop thrust line up properly, so it wouldn't climb so hot with two people. I'm still tweaking the bird. I hope to have it all correct this weekend. Regards, Bill

----- Original Message ----- From: xair@... To: X-Air_Ultralight_Aircraft@... . Fuel consumption is nearly identical between the Jabiru and my 618 although some of our customers are using up to 18 liters per hour on there 618's ?? - (they probably need to be set up a bit better). Better in which way? I get about 16.5 L/h at 60Kts, 18 at 65Kts and over 20 at 70Kts, but that should be normal?? I can also stay aloft on 8.5L/Hr too! I am sure if someone could come up with some sort of engine fairing for these engines that better consumption figures could be acheived. If you look at the size of say the Jabiru hanging out the front and imagine the wind resistance..... it must have a big effect Fairing for the 618 would be lovely too! Peter

Hi Gordon I have a 2.2 Jabiru on my Xair and suffers on climb due to the thrust line, however Bert Flood has manufactured a replacement bracket for the Xiar to take the 912 and I am trying to get hold of one of these brackets to fit to my Xair so I can lower the thrust line and improve the climb rate. The engine bracket made by Jabiru for the 2.2 bolts directly into the provided holes on the plate for the rotax engine, so I see no need for Jabiru to make up another bracket if one has already been constructed by Bert Flood. My Xair with the 2.2 Jabiru cruises at 65 knots on 2800 rpm making the 4 stroke engine very quiet, safe and reliable to fly. cheers Tony

Just to clear up the information about the engine brackets. Bert Floods has agreed to design a bracket which will fit the Rotax 912, if and when we start ordering 912's for our aircraft. Our conversation went something like, if you can come up with an engine mount to suit our aircraft then i think more customers would consider a 912. I dont think Bert Flood's would like to put the work into a bracket if it's to be used on an opposition engine. I will do two things. 1. Ask the factory in France for more information on their mount, and who made it, can we have drawings etc... and 2. Put the word out to find a suitable person to fabricate a new mount specifically to suit the Jabiru and Rotax 912 engines. There are that many planes out there now flying around Australia i am sure if either engine importer got there act together and did a mount then their engine would sell in reasonable numbers. Every customer asks the same question.... Can i put a 4 stroke on the X-Air ? and why wont the Jab or 912 bolt straight on !........ if it was as easy as saying the Jab/912 will fit with the optional $300 engine mount then i am sure they would buy them. Easy way....... find someone who can design a mount and do some welding. Thanks Michael

What are there any restrictions/requirements necessary for a manufacturer to have when looking for a manufacturer? cheers Tony

Regards, Bill What do you mean by not set the thrust line up properly ??, did you have the gearbox upside down, what engine ?? I have about 25 hours in "F" models and they should climb a little bit better than the standard plane on the first stage of flap, i have found full flap on takeoff is just like throwing out an anchor, but having said that if you commence ground roll with no flap and then at about 35 knots pull full flap she leaps off the ground real quick. Someone wiser and more sensible than me told me it increases your chance of stalling dramaticaly, so he did not recommend it as part of normal flight practices. Overall we find the "F" model a little bit faster (about 5-8 knots) the roll rate is also about double, other than that they are very similar. Please let us know what your playing with and make sure to post a picture of your aircraft in the Files section in the folder "Aircraft Colours".... i am trying to build a library of different colour schemes for customers who are always asking what does a pink and purple look like etc... Thanks Michael

Position the stick centrally and tie in place, tie it firm because it's easy to move the position when adjusting the ailerons. Using one person on each wing, go to the outboard location where both the struts connect to the wing and put a good straight edge in there - wedged hard against the leading and trailing edges. You can now use these secure straight edges (piece of timber etc..) to adjust the position of each aileron. The factory recommends touching each straight edge but our preference is to have them raised about 1 cm (1/2 inch) i find the plane flies a little faster and seams to be very neutral in all aspects of flight. If they are adjusted down to touch the rulers the plane seems to yaw a little bit in the turns, adjust them up and it doesn't. Finally, don't forget to safety wire the turnbuckles using a standard figure 8 wiring method. Your done !! she should fly perfectly balanced and without any vices. Thanks Michael
