Scratchbuilt 1 Meter Balsa DLG - Detailed Build Video

[@ripmax333]

It's a shame there are no plans for this model, I'm sure if you sell them you can make a good profit for your next project. well done with the build.

[@VC_27]

You are tempting me to get back to the hobby............

[@axelsmith209]

Did you just cut into the carbon rod to attack the horizontal stabilizer?

[@AeroCraftAviation]

Yep (with little riser mount in between so the elevator can move down without hitting the carbon rod)

[@axelsmith209]

Thanks 😄

[@axelsmith209]

Hello I’m having a hard time finding the tapering wing spars for the wing

[@AeroCraftAviation]

Sand or carve them yourself by hand, using some techniques from my other videos. Cheers. :)

[@axelsmith209]

Would it be the same exact airfoils detail but just half the trailing edge?

[@AeroCraftAviation]

@@axelsmith209 Right. Keep only as much of the airfoil as you need

[@axelsmith209]

Hey do you know the dimensions of the glider and also how do you get the tapered airfoil cutouts? Thanks, love your build

[@AeroCraftAviation]

Thanks for your comment. Span is 1 meter. Root chord is 175 mm. Planform is approx. an ellipse. Tapered airfoil cutouts are cut by hand. Cutting guides can be printed from airfoiltools.com . Navigate to Airfoil Search.

[@axelsmith209]

What would be the maximum and minimum thickness of the airfoil and the maximum and minimum camber?

[@AeroCraftAviation]

@@axelsmith209 Look for the Mark Drela Bubble Dancer airfoils on airfoiltools . Frankly any of them will work but the thicker ones like AG16 are better for a little floater like this

[@MasboyRC]

This is so cool !! Can't wait to see it flying

[@AeroCraftAviation]

Several flight videos have been posted. Have a look through my channel, I’m sure you’ll find then. Cheers! :)

[@gordonyork6638]

Does no one put washout in their wings anymore?

[@ricomon64]

Looks great! I can hardly wait for the maiden.

[@AeroCraftAviation]

Thanks! That’ll be coming next week! :)

[@AeroCraftAviation]

@@ferce889 Yep! A few of them. kzbin.info/www/bejne/pZ3Mh6iiiruAjrc kzbin.info/www/bejne/pWi1XneNmMqqmc0 kzbin.info/www/bejne/jXyTZaKPZ7ieh9E

[@Doug56]

How will you launch it, no finger peg on the wing tip.

[@AeroCraftAviation]

Grip the wingtip with thumb and fingers, and release at the end of the arm swing. Easy technique, alleviates the drag and weight of the throwing peg, and achieves about 90% the same launch altitude.

[@ЯромирФундукян]

give a link on plans pleese I need it so much!

[@AeroCraftAviation]

Sorry no plans are available. It's all in my head! Haha.

[@mosfet51]

Rough but a lovely little glider

[@AeroCraftAviation]

Haha yeah, these built-up designs are hard without CAD or a laser. Doing the best with what I’ve got. Glad you like it. 👍

[@axelsmith209]

What balsa covering did you use

[@AeroCraftAviation]

Parklite (lightweight version of Ultracote) plastic shrink film

[@axelsmith209]

All I could find was Hangar 9 UltraCote Lite Airplane Covering

[@axelsmith209]

Is it the right one?

[@AeroCraftAviation]

@@axelsmith209 It will not work -- too heavy. And shrinks too tight. The frame will bend. You will need to search many sites to find Parklite. Most sellers do not have it any more. Hard to find.

[@axelsmith209]

Ok thanks

[@civilsocietyprivateinteres1711]

Hello I love your builds they're super solid ! I got a question, I got an Anglewing designs mini pug dlg kit on the way and given the wings are balsa and need to be covered, do you install the throwing peg before or after covering?? Thank you in advance Zach

[@AeroCraftAviation]

Thank you! Glad you enjoy. Regarding the throwing peg. I actually don't use throwing pegs on my designs. I find I can still throw to 30 meters or so without a peg, and then I can ditch the extra drag and weight of the peg. (Remember that the peg actually infers a weight addition of twice its weight, because it must be balanced out with weight on the opposite wingtip). But Since the Pug is designed with a peg, I would recommend installing the peg after covering. Cover the wing, then cut a hole where the peg goes. Before installing the peg, use a wire or something to poke lots of tiny holes in the film around the peg. That way the adhesive can seep into the wood around the peg without being blocked by the covering film. Also, that way any air trapped in the adhesive can leak out, and you won't get bubbly covering around the peg.

[@jdaveg5]

Thanks for your work

[@AeroCraftAviation]

Thank you for watching! :)

[@Sandokans]

Niceee. What glue for balsa you used

[@AeroCraftAviation]

Medium viscosity CA glue for small joints, 30-minute epoxy resin for tougher joints, Titebond wood glue for some joints, 24-hour epoxy resin for carbon fiber joints.

[@luke_atthat]

Impressive! Great work! Anxious to watch your maiden flight!

[@AeroCraftAviation]

Thank you!

[@loganreuter6072]

Also how long dose it take to sand down those wings?

[@AeroCraftAviation]

Took me about 4 hours. I start with the coarser grit paper, and work my way down to the super-find 600 grit.

[@loganreuter6072]

@@AeroCraftAviation Dang! you have waaay more patience than I do. that's about how long it takes me to build one foam airplane from getting the idea to getting it flying!

[@AeroCraftAviation]

Yes, these balsa builds take a while. To build this entire aircraft, it took around 28 hours.

[@ferce889]

i enjoy the choice of music

[@AeroCraftAviation]

Yeah classical music is always a favorite. Glad you enjoy. :)

[@kadytoast5190]

what im trying to build too, out of curiosity did you have to add any ballast for it to fly well?

[@AeroCraftAviation]

Well usually you get the best glide performance with the lowest possible weight. But ballast is sometimes necessary to get good launch height or fly in strong wind. So I only add ballast for windy days or high throws, because it will always decrease the glide capability.

[@loganreuter6072]

Yesssss! A new video!

[@yankl1]

Hi, Do you have the plan for this DLG? Thanks

[@AeroCraftAviation]

Sorry, there’s no plan for this. It’s all in my head. 😅

[@allenmoore9848]

Hey I am the first to comment! Making the video for it is just as much a skill as the model building. This should be a good flyer, really enjoyed the video.

[@AeroCraftAviation]

Congratulations on posting the first comment! Yes, editing these videos is certainly a skill. This one took around 6 hours start to finish. And the glider flies great; maiden flight video coming next week! :)

[@goldenfish77]

Very nice work! The building steps and the video are awesome! I would like to see how to connect the controller parts to each other.

[@AeroCraftAviation]

Thank you! I am working on a couple more long build videos, so I will spend more time addressing the connection of the electronic parts. :) Thanks for bringing it up.

[@goldenfish77]

@@AeroCraftAviation What kind material covers the wing? Maybe it is duct tape? Thanks!

[@AeroCraftAviation]

@@goldenfish77 It's this material here. It is a plastic film that can be heated up to shrink tightly around the wing. www.stevensaero.com/product/parklite-blue-midnight-2m-roll/

[@goldenfish77]

@@AeroCraftAviation Do you think this wing shape is two pieces 0.5 cm thick foam boards (shape is Your beautiful wing shape) in the middle with a foam stiffener and then covering with adhesive tape, it would be good for a DLG? The top wing shape is larger a bit than the bottom. Similar to the Spinster DLG: www.flitetest.com/articles/foamboard-spinster-f3k-beginner-dlg.

[@AeroCraftAviation]

@@goldenfish77 Yes, what you describe will work. I have built a few foam board DLGs before, with that method. The flight ability is pretty good.

well done, looks great, cant wait for maiden flight :)
