I am already decently experienced with designing aircraft in flyout and simpleplanes (simpleplanes is a game about making planes while flyout is more akin to software), but this video opened my eyes to advantages and drawbacks of wing loading among others
Appreciate your video! Looking forward to more of this flight mechanics for model airplanes! A small piece of advice on the tech part of making the videos: if you would use a lav mic, mounted on your shirt, it would dramatically increase the audio quality of the recording.
I usually fly indoor gliders (F1N), these usually have WCL between 0.2 to 1 (depending to the categories and designs). It usually flies for 10 to 50 secs for single indoor flight
May be a bit late, but if you know where your center of gravity is with and without the power source, assuming you are using a prop and the center of thrust is in the center of the prop somewhere in the hub of the propeller blades, as long as the center of thrust and weight are in line the plane should be pretty stable, otherwise you have a turning force in the opposite direction of the imbalance you need to counteract
Nice video! Is wing area orthographic area for WCL? Also when we define CG, should we calculator where CG at first by area of wing and stabilizer , and then make sure front side of CG and rear side of CG have the same weight?
I’m not sure what you mean by orthographic area. On a plane with a conventional tale it would be only the area of the wing, but on a plane with canards it would be the area of the wing and the canards since the canards provide lift too. It’s generally best to estimate the CG location before starting to build the plane and make adjustments to your design if you think it might be too difficult to get it in the right location.
@@DesignYourOwnAirplanes-xd6lz Thank you so much. What I am trying to say is should I use actual wing area to get WCL or wing projected area when calculate WCL for dihedral wing or anhedral wing
:54 it is the opposite of smart to: use this much sweep in the main wing and stab of a GLIDER, and to locate ballast mass aft of the main wing. 9:55 design does not have to be so math-intensive. a few ratios will go a LONG way; they can be used WITHOUT the need for SOFTWARE and a computer. for example: in the case of a free-flight glider, the span of the horiz-stab should be equal to twenty-five percent of the wingspan. and, vert-stab height should be equal to a bit less-than fifty percent of the stab span. root chords of stabs should be equal in length. d
5:30 wrong. this is center of mass (c-m). NOT cg. consequently, your explanation is NOT correct. cg should be located at thirty percent of chord/mac; at the WING's surface. c-m should be located on the thrust line, at a point that vertically aligns with twenty-five percent of chord/mac. as indicated, in this illustration. s3.amazonaws.com/assets.flitetest.com/article_images/medium/truecg-jpg_1384168691.jpg
30% is not a fixed rule especially if the wing tapers off like in his example. How the wing area is distributed should be referenced not just the chord length. The ideal spot also depends on the type of flight characteristics desired. More nose heavy for stability and more tail heavy for maneuverability.

so glad to have discovered your series today!
Another great video. Look forward to seeing more. Well done!
5:35 The simple explanation remind me of the old black and white documentary in a good way.👍

I’d recommend Rode smartlav+ and an extension TRRS cable to your phone 😊
Thank you so much. You're doing thinga my professor couldn't do in a week just in 12 minutes

hi you make learning fun Look forward to seeing more. Well done!
great information delivery!
Hey great video. Can you please make a video on making these gliders rubber powered. Please

Very useful video. Many thanks!
I wanna become Aeronautic engineer:D
Great information. Thank you.
Thanks so much 😊
Gutes Video, danke
I need the dimensions please it's for my university project thanks
The previous video includes dimensions
Very much impressed by your vedios

@@linsfunbox4052 you should use the actual wing area.
@@DesignYourOwnAirplanes-xd6lz Thank you so much! it is much easier to use actual wing area.
Excellent.
got yourself a sub :)
Is there your vedio on how to install mini moter on these gliders
You should check out the FliteTest EZ power pack.

Que material usaste. What material uses
I use Adams Read-Board
wow
Yes🎉🎉

It would not be smart if this swept wing glider failed to reach its objective. What is the objective of this glider?
Are you for real?
lol "crash course"
anger
DONT SHOUT ON ME!!

Please explain under which circumstances the center of mass and the CG of an airplane are not in the exact same location.

The ideal spot also depends on the type of flight characteristics desired. More nose heavy for stability and more tail heavy for maneuverability.
