On an earlier thread I discussed Discus Launch Gliders On A Budget? http://www.wattflyer.com/forums/show...t=13314&page=2
Which was mainly concerned with the F.A.I F3-K upper size limit of 1-1/2 meter wingspan. Several members posted asking about the smaller gliders, sometimes called "SAL" (side-arm launch) or "Mosquito" (1 meter max span) gliders.
Well, I found a few ARFs and one RTF, Here's the four I found so far, starting with the smallest; MiSAL-2 DLG from Edge RC http://www.edgerc.com/MiSAL%20DLG.htm

I'm sure there's more "micro" gliders, let us know if you've tried' em!
Hi Franny, Long time no yak!
The Alula caught my eye also. I've read some comments on the "Budget" thread that say it flys pretty well, might have to try one.
See you soon, got a model magazine for you!
Enduro Composite Models have a small (40" wingspan) glider kit called the Apogee Sport.http://www.flyecm.com/inventory/Apogee_Sport.asp
This is a discus-launch glider kit, not ARF. All laser-cut balsa, uni-carbon reinforcment, AVIA tapered, wrapped carbon boom, teflon tubing, stainless steel control rods, all carbon launching blade, full size plans and construction booklet with color photos. The model is based on Dr. Mark Drela's Apogee DLG design.
Wing Area- 198.4 Square Inches

And a great DLG site in the Czech Republic, dozens of links for F3K, DLG, SAL's, Micro gliders, build threads, photos; http://www.tmrmodel.cz/links_dlg.htm
o that was a typo on the site, its actually the AR6400 the brick yes, thank you for correcting that, its best to fly this at dead air on a hot day, it glides forever. in the video it was a cold day so airtime was low. this little guy actually can be flown in 5mph winds, anymore and yes it will get blown away
Vladimars Model's 'Elf' is IMHO one of the best micro DLG's. At 1M span and just over 3oz (95g) in weight it makes all the rest, even those costing much more, look a little 'porky'. This is a micro DLG with 'real' DLG performance.
The Elf is an amazing model and great value, but many would argue not exactly 'budget priced'. If you want good performance for minimum cost then the MiMi is worth a look, plan is free and available in both built up wing and solid balsa: http://www.rcgroups.com/forums/showthread.php?t=840763
hey JetPlaneFlyer, not to many people in this bull***t economy can afford food yet alone DLG gliders well over $200 not to mention the ELF which is no longer available.... Micro means MICRO, well under 21" of wing span, i dont think you can find anywhere online or your local hobby shop that sells a "micro" DLG glider for under $40
sure i myself would love to own an ELF or a Binary V2, but who wants a week of build time with Kevlar and epoxy?
I appreciate some are on a tight budget which is why i put a link to a *FREE* DLG plan. If you have a $40 budget and want a mini DLG with genuine full size DLG performance and dont mind a bit of balsa bashing, then the MiMi is the way to go. Having said that the economy may be in the toilet but there are still those who can easily afford $200 so let's not make ridiculous generalisations that everyone in the world is starving!
Not sure how you came to the conclusion that the Elf was not available It's still in production and is in stock and available from both of the stockists I linked to.
We all have our own ideas what 'micro' means. The official Mini/Mosquito DLG class allows gliders of 1m span (the Elf was built for this class). The opening post of this thread actually says gliders of 1m span......I assume you just made up your 21" definition?
As for the "week of build time with kevlar and epoxy". The Elf comes fully complete except for RC installation. You don't need to do anything with kevlar or epoxy and assembly takes only a couple of hours. The Topsky models on the other hand do need quite a bit of work to finish.
Taking nothing away from your little Micro-D glider, it looks like a lot of fun. One hopefully constructive comment; In the video I think I could see a lot of wing bending on launch. You would stop all of that if you put carbon on both the top and bottom of the wing rather than what looks currently like the top surface only. This does not necassarily mean more weight because half the width of carbon placed top and bottom would be orders of magnitude stronger than a single wide carbon strip placed top only.
Sounds about right to me. I've got a 17" span freeflight glider here, if I weight it together with an AR6400 and a 110mAh battery it's 15g total. So a 21" glider under one oz should be quite achievable.
Yes, its around .8oz, i use hot glue in some parts e.g elevator to the boom and rudder to the boom, if you use thick CA, you can achieve sub .7oz, on a calm hot summer day, i was able to catch thermals, she flew for 5 minutes before i had to bring her down any other DLG this size specially those made out of balsa will not achieve thermal lift
