Basically what you are saying is to put a blank piece of paper in between with the same spacing as the other ribs and to keep the spar hole the same for the w1-w3 ribs and the w7 rib. What other little tricks did you do to get the weight down. I am using 1/16 on the tips and using the 1/8 boom. I also thought about using 1/32 balsa with one layer of glass on either side (not both) and after curing puting some lighting holes in the tail planes. Then using a light weight covering for the holes only. I will have to experiment with the tail to see which is lightest and strongest. I want to be able to do moderate SAL launches.

Clark, Use the same rib spacing as the rest of the ribs. Cut the plan apart at the W3 ribs and tape a piece of paper between the cut. Keep the same spar hole in the W3 rib and the tip rib.

When adding the extra rib, did you have to change the hole in the rib for the spar or did you just leave everything as on the plans. Also how far did you space the rib out? Is there a chance you might have a drawing of your moded wing?

John, I see I stand corrected on the BUG's ability to launch to 70 foot hieghts and survive-- I'm sure that's because of the thoughtful design mod's you made. I agree that there are two very different approaches here which is why I wrote about building them "correctly" in quotations. "Correcetly" means for my intended purpose not the only right way. Kudos to all of you who have built a great DLG launching BUG. I'm really enjoying the lighter end of things, but I am definitely intrigued by all of your DLG versions now. The next BUG I build will be more along those lines. However, at the present moment, I think for my time and money, the 35-40", 3.5-4 oz niche is better filled by the Seeker (www.liftworx.com). I'm building one now and the kit and design are OUTSTANDING. My range of planes from light to increasing wingloads are as follows. 1. Bug 35" WS and 1.8 oz/ft WL 2. Seeker 40" WS and 3.5 oz WL www.liftworx.com 3. Super Soarwatt 72" WS and 4 oz/ft WL motorglider http://www.rcgroups.com/forums/showthread.php? s=&threadid=157881&highlight=zovy+kat 4. Osiris (soon to be built) 60" WS and 3.5 to 4 oz WL (hopefully!) www.icare-rc.com 5. Bolo 60" WS and 7 to 12 oz/ft WL (depending on ballast) www.upslopesoaring.com So you can see I already have a lot going on in the 4 oz/ft range. The BUG is about the only plane I can get down under 2oz/ft, so for now, that's how I build them. With the 5 planes in my quiver, I can fly just about anything from no lift to ligth thermals to hat suckers and booming slope lift. The link to the SuperSoarwatt will give you an idea of the terrrain and conditions around here. Thanks all who've contributed to this great forum.

I want to make a 1m class--approximately 39 inches for SAL launches. I do want to build a super light one too for floating on small hills. I finally could open the files on the homepage. I had to long in ID's for some reason. I guess in the past I used one id for my heli groups and a different one for my glider groups. Don't ask me why it is this way.

Rib W3. the first rib to either side of the center section. John On Mon, 15 Mar 2004 07:12:50 -0600 clark driggs <invrtd@...> wrote: > which extra rib number did you add. > ----- Original Message ----- Sign up for Internet Service under $10 dollars a month, at http://isp.BlueLight.com

which extra rib number did you add. ----- Original Message ----- From: John To: BugHLG@yahoogroups.com Sent: Sunday, March 14, 2004 11:01 PM Subject: [BugHLG] Re: 1.8 oz/ft2 BUG Thanks for your reply, Jason. The trees at my field are over 65 feet tall measured by a phone lineman's pole and I launch my bug to just higher than the treetops (I estimate 68 - 70 foot launches). I've done this hundreds of times without any breakage. A shoulder injury prevents javelin launching so SAL is necessary for me. When I built my bug, I didn't order the contest grade balsa but I used the lightest balsa I had (about 7-8), and a lightweight wrapped tail boom. This boom weighs about the same as the 1/8" pultruded CF tube but is stiffer and larger in diamater. The boom diameter is large enough that you can put holes in the boom to allow the pushrods to exit the boom in front of the tail, making pushrod hookup easy. The link for this boom is posted in the Links section (replacement for Skyshark 2P). I did fiberglass the fuse for strength adding more weight. All radio components are forward of the wing LE. I used Hitec HS-50 servos because they are lighter than the Pico BB's. The weight of my x-tail pieces are not near as light as your v-tail. The original flying weight of my bug was about 3.8 ounces but it is strong enough for 70 foot launches. Light with incredible thermalling ability but doesn't launch high VS heavier with decent thermalling ability but launches high. Two schools of thought with positive points for both. For me, the answer is somewhere between your 2.6 ounces and my 3.8 ounces, but with the strength to launch high. I'd be satisfied with 3.25 ounces and the ability to SAL launch to about 60 feet. The weight of my x-tail pieces for coming Bug #2 is 6.7 grams with CF reinforcement and fiberglassed fin/rudder. Already have the 250 mah lipoly (Etech) 5.5 grams. More to come but another project first.

Thanks for your reply, Jason. The trees at my field are over 65 feet tall measured by a phone lineman's pole and I launch my bug to just higher than the treetops (I estimate 68 - 70 foot launches). I've done this hundreds of times without any breakage. A shoulder injury prevents javelin launching so SAL is necessary for me. When I built my bug, I didn't order the contest grade balsa but I used the lightest balsa I had (about 7-8), and a lightweight wrapped tail boom. This boom weighs about the same as the 1/8" pultruded CF tube but is stiffer and larger in diamater. The boom diameter is large enough that you can put holes in the boom to allow the pushrods to exit the boom in front of the tail, making pushrod hookup easy. The link for this boom is posted in the Links section (replacement for Skyshark 2P). I did fiberglass the fuse for strength adding more weight. All radio components are forward of the wing LE. I used Hitec HS-50 servos because they are lighter than the Pico BB's. The weight of my x-tail pieces are not near as light as your v-tail. The original flying weight of my bug was about 3.8 ounces but it is strong enough for 70 foot launches. Light with incredible thermalling ability but doesn't launch high VS heavier with decent thermalling ability but launches high. Two schools of thought with positive points for both. For me, the answer is somewhere between your 2.6 ounces and my 3.8 ounces, but with the strength to launch high. I'd be satisfied with 3.25 ounces and the ability to SAL launch to about 60 feet. The weight of my x-tail pieces for coming Bug #2 is 6.7 grams with CF reinforcement and fiberglassed fin/rudder. Already have the 250 mah lipoly (Etech) 5.5 grams. More to come but another project first.

Sounds real nice. Did you use 1 extra rib per side to get to 35"? I am building my next bug w/ the epp nose as well. Too cool. --- In BugHLG@yahoogroups.com, "jason_wasylyk" <thetoothdoc@s...> wrote: > I just finished a project I envisioned long ago but was unable to > get to.

Well, 'cuz you asked.... here are some (hopefully controversial enough to spawn some discuusion)details: First let me say that I differ from the popular notion that the way to improve on the BUG's performance is to add a DLG style x-tail and chuck it higher. While this is UNQUESTIONABLY the way to maximize dead air time in a 60" competion class DLG contest, I don't think this style of building or flying makes maximum use of the BUG's most desirable qualities which are its LIGHT WEIGHT (if built "correclty") and RADICAL manouverablilty (again if built "correctly"). I concede that a 60" DLG launched to 100 feet is going to outfly a 60" DLG launched to 40 feet, But I contend that a 2.5 oz BUG launched to 20 feet will outfly a 3.5 to 4oz BUG launched to 60 feet (which I can't see anybody launching a BUG to without blowing it apart). So, I prefer to leave the v-tail for maximum tail lightness and to allow the use of a light (4g) Kokam 145mAh cell for juice. Most importantly, the use of the v tail and a gentle javelin or side-arm (NOT DLG) launch allows the use of smaller dimeter (LIGHTER)tailbooms which is where the MAJOR weight savings is to be had. I've already posted on this in the past and stirred the pot a bit. Many others contend that the 1/8" CF tube I favor is too sloppy--maybe if your trying to full force discus launch. Anyway, you can look up details of this discussion in previous posts. So, the fun of the BUG is in my opinion building lite and manouverable and having fun down to 10 and 20 feet altitude where thermals form tight and fast. I suspect that not even a top of the line 60" DLG can work the bubbles this gem can at 10 feet off the deck. So, the major departurs in the way I build my BUGS are: 1. Contest wood only. 2. Use of Modelairtech Clearfilm for covering and WBPU on bare wood. No Color. 3. Use of CST's 1/8" cf for tailbooms 4. single cell Kokam 145 cell from www.b-p-p.com 5. positioning all gear forward of foremost bulkhead for balance. 6. GWS pico rx and pico BB servos 7. extended wing as described in other posts 8. Vtail (NO DLG style tails-- I built one and the lightest i could do is 6g compared to the 2g vtail. That 4g diff takes about 12-15g more weight in the nose to balance. 9. don't cover any part of the fuselage with f/glass. It's too heavy. Try this-- 3M-77 forward of the wing LE, then apply 3M tartan crystal clear packing tape (1mil thick). Then iron down. VERY Strong and on ly adds 1g. Cover the nose forward to the EPP block (see below), then coat with goop. A point of interest is that in order to get her to balance with the single Kokam 145 cell, I had to put the Rx, batery and both GWS pico BB servos forward of the foremost bulkhead. That leaves the entire compartment under the wing empty (except of course for the pushrods). As this compartment is right under the CG it'll make a perfect ballast box should I wish to fly at the more usual wingloads of 3-4 oz/sq. ft. Another GREAT innovation has been the replacement of the nose balsa block with EPP foam sanded to shape, spackled and coated with marine GOOP thinned with toluene. VERY smooth and resilient. This cushions MAJOR landing impact and never chips and dents like the balsa block does. Try it-- you'll never go back. I'll post photos later. For the time being, I'm going to have fun seeing what a tip- launchable, extremely nimble glider can do at under 2oz/sq/ft. Should be lots of fun

Jason, That's incredible!! How did you do it? Give us some more details. How about some photos?

I just finished a project I envisioned long ago but was unable to get to. I built an exteneded wing BUG (35") to 72g. Thats 2.6 oz and 1.8 oz/ft2. Should be a real floater. Will try a maiden tomorrow if wind is calm.
