1m balsa DLG glider with ailerons - scratch build DIY

[@davidculver5366]

A. Filos, thank you for all you do for us. So many people get inspiration from your work I know I do! Thanks again. David

[@afilos]

Thank you David for your kind words!

[@vet137]

The mixing is awesome so freaking cool!

[@afilos]

Thanks

[@davidfischer1978]

Thank you for all your vids….You are very much appreciated……Are the wings on this one sold balsa shaped & sanded to shape….aWhat is the wing chord?……again appreciate you….Dave….Australia..

[@afilos]

Thanks Dave, yes solid balsa, chord is about 13,5cm most part, but needs to be waterproofed. Balsa is very sensitive to moisture, so better use clear coat on it or something similar.

[@MarkJimenez-dw1tl]

Is it possible to install a Vario on a fly sky ?

[@RCPlanesAndTravels]

Great electronics layout! And what are the aileron deflection angles for different stick positions and why?

[@marurb]

Very nice and simple construction. I like your idea of just letting the boom be the fuselage. How did you join wing and boom and wing halves? Both with a glass fiber strip/epoxy?

[@afilos]

Thank you, wings halves as you said and wing to boom, plain thin CA. Check out my build series kzbin.info/aero/PL24KP2KUegseP4qjXo-nDTnHuhzUaAMEe

Hi, thanks for all informations. Just a few questions: receiver is directly connected to battery? Is it 1s 3,7v 400mah? That Micro servos operate between 4,8 and 6 volts? Is it enough from that battery? Thanks a lot

[@afilos]

Yes to all ! 1s 400 is good for even 4 servos, and the flight time will be more than an hour (1-1.5h). Servos will work perfectly, just a bit slower, but no problem with gliders.

Do You think that FlySky FS-iA6B Receiver 6CH 2.4G (Input power: 4.0-6.5V DC) would works with an 1C 3,7 V 450mA Li-Po or I have to use 5V dc-dc converter with an 7,4 V Li-Po? Thanks!

[@afilos]

No it won't work, it loses signal and you will crash. You need a step up or a step down voltage regulator, but then you add extra weight. You should use the one i use, which is ok for a 4 chanel plane if you solder a battery connector directly to the pins of the receiver.

[@goldenfish77]

@@afilos Thank You for Your answer! So it can cause that the battery (3,7 V) will connect to the receiver without any cable and there is no waste energy?

[@afilos]

​@@goldenfish77 you solder a cable (black, red) that ends to a battery connector on the two pins of the receiver and at which you connect and disconnect your battery. If you want i can send you a photo.

@@afilos As You tell me that I have to see RCGroup forum, I found this thread: www.rcgroups.com/forums/showthread.php?958260-3-7V-receiver-battery-OK Voltage booster it seems to be good (3-4 gram extra weight) for an 3,7 V Li-Po.

Congrats, nice job!

[@afilos]

Thank you!

[@mangiari]

How do you choose attributes for your builds? Just copying from other planes? Gut feeling? I mean distance of stabilizers from wing, size of stabilizers, outer wing shape etc.

[@afilos]

Mainly copying other plans. This one, as you can see in the video description, is a copy from 1m hawk dlg.

[@MarkJimenez-dw1tl]

What weight is has ?

Hello, I'm new to RC and want to build a small dlg. Seems like you have only elevator and ailerons for control surfaces correct? No rudder?

[@afilos]

Yes correct, no rudder.

[@C11ffH4ng3r]

Also looking to build my first rc plane and will do a balsa DLG. What would you say is the difference between ailerons and rudder? Rudder would require one less servo i.e. save some weight? What about rudder and ailerons vs elevons(?) in a V-shape on the tail? To me it looks like the general design of a rudder sticking down would be prone to damage? Also what kind of flytime do you usually get with the receiver/battery?

[@afilos]

@@C11ffH4ng3r you can't combine v-tail with DLG, you wont be able to launch straight. Indeed the tail is prone of braking on bad landings, that why we try to catch them rather then land them. You can fly equaly well a rudderless plane and a full house plane. Flying time would be around 1h with this setup.

Nice....No fly video? Will there be a build video? ✌

Thank you, check out the fly video kzbin.info/www/bejne/oGGsqGCBf5WXiMU and there is one where I catch my first 3 minute thermal coming soon. There is no build video but I have posted in the comments all the details for you, happy to answer any questions for build details...

[@erickalvarez900]

How do you shape the profile of the wing? I see you have a link to the profile in the description

[@afilos]

The plans is a true copy of the hawk (see comments) and the airfoil is a AG46ct -02f rot. (airfoiltools.com/airfoil/details?airfoil=ag46ct02r-il). Use a 0.8*10*100 balsa sheet 72grams, cut it in half and cut the wing tips as per the plan. Glue a hardwood strip (I use a 2,5mm basswood) onto the entire LE (this is a must!) and give the shape of an airfoil to the two wing halfs using the following method www.charlesriverrc.org/articles/construction/markdrela_airfoilshaping.pdf. Stick the airfoil paper profile on to the root side of each wing and start marking where you want your cut's to be . Bottom wing side is flat. Shape the dihedral of the wings the way I show you in my videos and glue them with 5min epoxy. Glass the entire wing root connection top and bottom with a 3cm strip of a 25-80gr/sq2 fiberglass (I used a 25gr/sq2) with 5min epoxy. Balance the wing after installing the wing peg. Good Luck

[@ДмитроМинзак]

What servos did you used?

[@afilos]

Check out the video details I have all the information listed. Any 5g servo will do the job, in this build I used these www.banggood.com/3_7g-Micro-Digital-Servo-GH-S37D-For-RC-Airplane-Helicopter-p-1116559.html?akmClientCountry=GR&rmmds=myorder&cur_warehouse=CN

[@vonskipppy1152]

That was one boring video (you just luv fiddling with the control sticks dontcha?). Looking forward to your next video where you show yourself applying 24 hr epoxy on the center wing section and watching it dry.

[@afilos]

Hahaha, Best comment ever! Nice one! You just made my day!! 100% TRUE! Actually, I have also uploaded that video.. kzbin.info/www/bejne/bIDVf4p7lr-Aq7s
