I did what was recommended. I am still not done. Ran out of carbon for the other wing half since I built the extended wing and used the 1/8 rod for the boom also. I think I may have been a bit sloppy with the glue plus I did not use contest grade balsa. I think the next time I go in to buy balsa at the hobby store I will take my gram scale to get the lightest sheets. I am also thinking about using a cruisable tail for SAL launching. My next project will be to build a 40 inch with a double spar. Possibly an upper and lower light wood spar with carbon stripping along the spar with shear webbing. This will make the wing much stronger and will take harder SAL launches. This 40 incher will be on the back burners until I finish building my 35 in which I will finish next week when I get some carbon in and finish my new Slingshot DLG from Germnay. The slingshot is beautiful 1.5m vacuum bagged wing DLG with carbon boom and pod with bagged balsa tail planes for only $170 shipped.

Did you find the file folder on the yahoo group page with the mods you were looking for. I just completed half of a wing that is going to make a 35 in bug. Just install another w3 rib and adjust the spar holes for the remaining ribs. I just sanded the 2nd w3 LE back by puting some sand paper around a 1/8 dowel to keep the bending of the dowel in a curve like shape. I kept the alignment of the spar between ribs w1 and w7. It wasn't too difficult to do. John G helped me out with the info. I did not use the large boom the instructions say to use. I used a 1/8 carbon rod and I know several other who have too. Also I used 1/16 inch balsa fort the tips instead of 1/8 inch. I also plan on using 1/32 balsa with a thin layer of apoxy for the tail. This may be too thin and break so I will probably actually add some .5oz glass to one side only. I have weighed everything that is built minus the one wing half with radio equipment and will be under 4 oz. I don't know how John G built his 35 in bug so light. > > > > Clark > > ----- Original Message ----- > > From: Jim H. > > To: BugHLG yahoogroups.com ; jason_wasylyk > > Sent: Friday, March 26, 2004 2:58 PM > > Subject: Re: [BugHLG] Re: 1.8 oz/ft2 BUG > > > > > > jason_wasylyk on 3-14-04 7:42 PM wrote: > > > > > 2.

Clark, Jason (also known as Zhack) is the one who built the ultra light bug. My x-tailed version came in at 3.8 ounces. Check Zhack's description of 'adding lightness to the bug' in the files section. John G.
