Scratch Built DLG Slope Glider From Balsa, SilverHawk, ULTRA RC
Вставка
- Опубліковано 7 гру 2020
- My friend James built this awesome custom slope glider from balsa and in this video, we show you all about it.
definitely worth seeing if you like expertly made precision aircraft.
it is a remote control glider which was built for a slope but can be used as a discus launch glider.
If you liked our video showing how to build a balsa wing this will also float your boat.

James' hair looks great
Great video. It actually looks better on camera, especially when it flies. Great work mate.
I build and fly pod & boom as well, but I run the stab wire THROUGH the boom to a horn on the back of the empinage. Works very well and less to snag on brush if I land without catching.
I don't build DLG, though. I do soaring in thermals and launch with just a toss into an updraft, which you learn how to recognize by watching wind acting on grass.
You can easily build in camber using slabs of laminated sheet foam carved into shape using an undercambered wing rib as a pattern -- just sand and check often. Easy, really.
Fantastic build! That is so awesome!👍😎👍
Thanks for watching ULTRA RC mate! !!
I appreciate your support!!!
Yeah im happy with it!!
looks pretty good and nice little flight,happy new year
Espectacular 👏👏👏👏👏
Very nice dlg!
Молодец парень!💪🏻👍🏻
Adding a second servo for the ailerons would allow you to add a bit of camber to the wing, either fixed, or variable through radio mixing, or with a cheap external v-tail mixer to give you flaperons. Nicely designed model. Clever use of the inboard "winglets" to mitigate tip stall tendency. Where is the c.g.? Seemed like it could be moved forward a bit.
How did it slope? Id say fairly good in nice winds. I have several with that wing structure and they all slope very well. Never DLG any of them.
Hello, I loved your plane and I was wanting to try to recreate it. Is there any chance you know how long and the thickness of the carbon rod on the back and how long the plane is in general? Thanks a lot 😄
Nice Job, Bro!
How much does it weight?
impressive
Very cool🤘
Thanks for watching ULTRA RC mate!!!
I appreciate your support!!!
Danke !!!!!!!!
*Nice DLG brrother big like 👍new friend is here to visit & listen. Hopefully you and your family are always in good health and success, amen ...🤲🏻🤝🏻🙏🏻🛩*
Thanks for watching ultra rc mate!!!!
I appreciate your support!!
@@CORINKERSTEN *your welcome my friend thanks 🤝🙏*
May I know how long it took you to assemble the whole plane ?
3:03 What is the left stick controlling here?
hope you do a build video with the new wing you are going to build.
Good idea mate I'd love to just we are both so busy:(
Thanks for watching Ultra Rc Mate!!!
hi i am building a DLG glider out of fiberglass and depron. I have a question, when throwing we must direct the joystick on one side?
I think no, he said, that glider has no rudder
@@volodymyrgolovchyn7736 I will try to launch as indicated... The glider must stabilize to go straight without intervening on the joysticks.
I still have not tested since its construction. I started another project and another. A biplane for 3D flight and a plane with a fishing rod
i want it
information. the original clark-y profile; 11.7% about three degrees of positive aoa is 'built into' this profile (with a wing mounted at zero-degrees aoa, relative to the lower surface of the airfoil.) at small scales, the performance of a correctly-designed flat-bottomed profile can equal that of a more difficult to make, semi-symmetrical airfoil

n-10 profile; 11.2% (so, thinner and less Lift than a clark-y)
airfoiltools.com/airfoil/details?airfoil=n10-il
an 'under-camber' profile is, effectively, a type of single-surface profile. its use should be reserved for powered models that Only fly slowly. eg., indoor models and slow-flyers. cheers a slow-flyer (with an S F prop.!!!)

Are you actually flying on 2 sticks or was that just some b roll footage edited in ?
He’s flying mode 1
You forgot to make that really importiant V shape of the ving !!!! And it looks stupid without the V shape...
Hello!
Thanks for watching Ultra Rc mate!!!
I appreciate your support!
You mean dihedral?
I know what you mean but in this way it is more acrobatic!!
information. pretty good work. except where it's not.
silly elevator control loads the servo, at ALL times. the use of full strip ailerons is Not recommended; on anything that is not a cropduster. those fences have NO place on the wing of a GLIDER. you have a less-than Accurate understanding of Profiles. the profile you describe would make More Drag!!! and, more drag is Not what you want, in an Unpowered aircraft. the profile should resemble a clark-y or n-10 profile. it is not clear, from the flight behavior/piloting, whether the design has some less-obvious flaws. some over-control from the too-long ailerons is seen. googletranslate
Thanks for watching ULTRA RC mate!!!
I apreciate your comment,
Especially on the airfoil type.
I have been trying to find out more information on this.
Cheers!
Hello, I am the builder of this plane. Thank you very much for this information. I am obviously an inexperienced builder, but I am very eager to learn.
Yeah I am aware that some of the explanations are not accurate because they were done on the fly. Surprisingly I have not had any issues with the spring pull system on the elevator. Probably because the servo is very over sized. And yeah I totally agree that those cards on the wings are much less than ideal but I can say that they did help the tip stalling significantly.
I do love people correcting my work because it is the only way to learn. So if there is anything else I should take into consideration when I do make the version two. Perhaps an airfoil transition from wing root to tip? Oh and I will never forget to put wash-out in my wings ever again. 😂😂
@@jamiewise7980 'wash-out' in the wing of a glider, NOPE.!!!! bc it would make MORE DRAG.!!! what you need is a Greater understanding of what constitutes Optimal wing design; for a given application. see the n-10 low-re# profile. because it is thinner than a clark-y, the n-10 will make less lift, less drag, and be 'faster'; with a higher stall speed. if faster is what you want. you are invited to View my tutorials. do you know how to make a Good, longer, pushrod.??? start with a PAPERCLIP and a bamboo cooking skewer! it is correct for a wing to make less lift, Nearest the fuselage. however, since that air is more turbulent, a lift-making profile will 'automatically' make Less lift, there. because the design of a wing/airfoil is Proportional, the making of a non-constant chord wing one requires careful THOUGHT. cheers

@@daviddavids2884 That's very interested, I'd love to check out some of your videos because they will certainly help me when I build more planes. Cheers.
@@jamiewise7980 if you do what i have done, which is to LOOK at an assortment of models of various types of full-size aircraft, you will see that PROPORTIONS are a KEY aspect of an accurate scale-down. those proportions provide a STARTING point, for the optimal design of a model aircraft. or, i can tell you.
