An evening on the WWW wielded loads of free plans for a slope soarer. Unfortunatley one one was not made of either Correx/ Depron/glass. The one I found was a Limit EX. Has anyone everbuilt one of these? Off to get some Balsa this afternoon and hope to make a start soon. Better still anyone know of a build thread. Google didnt sem to turn anything up but others oftern suceed when I fail.

Hmmmm. first hurdle...What on earth is quadrant balsa???? local shop seemed not to have a clue. There again i think he is a boat person really so that might be a valid excuse. Wing ribs marked out ready to be cut..........

 Quarter-grain, perhaps? (rib stock!)

|
 Isnt that the profile shape ? IE like quadrant hardwood beading etc ?

 Hi, i've built a limit ex. I may be able send you the article i wrote for my club mag about it. Or if you have any specific questions i can probably answer them. I don't know about quadrant balsa, but i used triangular balsa in the fuselage. Jonathan

that would be nice....Now i just need to figure out how to get an e-mail address on here without every spam merchant in the world getting my address. Any thoughts on that?

Andy, Click on the person's name you want to email privately, and it comes up with a 'mail me' box. Nobody else can see what you put in it, other than the recipient. Having tried it, it doesn't with yours, you haven't filled in your profile! And Jonathan hasn't permitted private mailing by ticking the box in his profile!

Done.....If Jonathan would like to send me his article that should now be possible I think...... Heres hoping.....
|
|
OK, i have enabled my email, but every time i try and mail Andy, it comes up with an error. I also can't attach it as an attachment.

It seems to have sent now i have sent it in 2 parts. Post if you get it Andy! Hope it helps

 I was wondering why you hadn't just called me for Julian Becketts telephone number......

Another quandry... I have just made a hot wire cutter. Do I make a foam wing instead of the built up one? Do I skin it with Balsa or glass and epoxy? What do you good people think is best?

So.....been playing with the wire cutter..... made a shape of the wings (X2) from the plan. Now, do i just stick the outer and innner ribs on the the relevant faces, as they will be staying there anyway and draw the wire across to give the wing section? I cant see any problems with orientation as its a flat bottom section and the leading edge is the front of the ribs....Any advice appreciated as i will try to cut the section tommorow. cant do it now as its raining and dont fancy the fumes in the garage.

There is another thread in here somewhere about cutting foam wings. You can stick the ribs on, but that makes it awkward. It is best to use the same two ribs (formers really!) for both cores, to be sure you get them both EXACTLY the same thickness. Mark on the formers the centreline, and then divide them both into an equal number of sections, marked off with a strongly coloured pen. This makes it easier to keep both ends of the wire 'in step' as you and your pal cut the core. One of you controls the cut, (usually whoever is at the root end) and the conversation goes something like - ready? starting the cut - now - and one - and two - and halfway - and... ...exiting now. With a little practice, you will find your own way of doing the job, as everyone finds a simple technique. The hard part is holding the core still while you cut it, because if you put a weight on the top, it impedes the wire and can give a starving horse effect to the core! Like all things modelling, it is a balancing act, getting the wire temperature right, and not cutting too fast, because that gives a corrugated finish, and not too slow, because the foam melts, all the time keeping the wire in step at either end! Have fun!

Most peeps use a template rather than the actual "ribs" - whatever you choose, ensure it is completely smooth, as the slightest roughness will cause the wire to drag and the foam will melt unevenly. Its important to start and finish at the ends of each rib at the excat same time, so practice !

Me and my mate eh? That will be a Black and Decker Workmate then! The only way i could vary the wire temp is by length. I have a set output PSU (12v @ 1000mA)and 1 thickness of wire ( 0.33 mm stainless steel braided) though is seems to be working well so far for stuff that was laying round in the garage! Got a cut width of 300mm at the moment wich is more than i need for this little wing. I did get the "starving horse" patina when trying to go to fast in the initail trails. As long as i go less than 10mm/sec seems to be as smooth a infants rear end! going even slower seems not to cause the foam to melt either!!!!!! have i chanced upon an ideal setup ? One thing I didnt forsee was the well tensioned wire slackeining off when it heated up. Needed to retofit a couple of decent rubber bands to take up the slack. Anyway, i cant remember having so much fun cutting things up since i was a child! Made a smashing fleur de Lys pattern free hand whn playing earlier!

Hi Andy.
I have built a Limit Ex in Depron. Here is a build thread. Here you can see the video / Robert
