The CG or Center of Gravity is the most important thing for RC model flight, because without setting up the CG correctly, your plane will have bigger chance to crash on the first flight. When Aircraft is flying it's hanging on its wing or surf on top of the wings so the CG is usually located on the wing but not always. For tradional configuration like plane with wing and stabilizer, the CG is always on the wing. Except the plane with canard the CG maybe located off the wing. CG is a center where the plane balanced when flying, not on ground but when flying. CG in aviation is actually quite complicated, but for model aircraft it's quite simple.
There are 5 Ways to find RC plane CG. I compiled them from the easiest to the hardest :
1. By using your eye and finger
2. Sticks and thread
3. Drawing lines
4. Online CG calculator
5. Smaller flying model

Hi Julius! Thank you so much for your videos! Don't stop doing them!
Best and most efficient explanation of finding CG ever. Thank you
Suwun, pencerahannya Om JP
This was an awesome video
Thank you so much Julius! Best CG explanation video ever!
Glad it was helpful!
Nice. this is the best cog calculation of all I have been watching! I subscribed buddy.
This is excellent! Really appreciate the practical and fast demonstrations and the delta wing tutorial was easy to understand.
Glad it was helpful!
mantap bang,,jelas skali penerangan👍👍👍
Your channel is invaluable to the hobby.
Thank you for the tips and the time you have chosen to give to your fellow pilots
My pleasure!
Salute to Julius. Thanks buddy
Hello Julius, this is a long awaited video tutorial on cg and I and the hobby thank you so much for putting it in plain and simple terms. I'm a pilot of full size aircraft as well as rc and have worked in the aviation industry yet this is the best explanation of the subject that's put forward well done
Glad it was helpful!
@@JuliusPerdana same for me as @Mick Bugden said, please make more video on these type of basics............like:
1. transmitter basics : its functions on the digital screen are really a confusing topic...... there are a lot of options on the digital screen..... please make a video on it...
Totally agree. I've been using one of those technices since the 70's. Good video.
nicely done om jul. find cg on all models are very important..
Thanks for the tips oms🙏
My pleasure
You the man!
Loads of great info! Thanks!
Glad you enjoyed it!
This guy so helpful. God bless you brother
Glad it helped
Just today i was thinking i should request you to make a separate video for the following topics, if possible, Pak:
1. Finding/calculating the CG.
2. Tips for ironing the laminated film without wrinkles.
3. Tips to laminate the Depron without risk of warping the foam.
And here you have answered my prayers! Two thumbs up! 👍👍
ok more to come
Thanks for the help
No problem
Tons of appreciation for your effort. Please continue sharing such useful videos 🤠
Thank you, I will
Perfect 🙏🙏🙏🤌👏👏
Good information ....Thank you
Welcome
The Boeing 747 is more complicated to calculate the taper ratio because the wing can be divided in 3 parts. Still can use formula for mean aerodynamic chord but the taper ratio is challenging to calculate before applying the formula for mean aerodynamic chord. Because the wing design of that airplane is crescent.
Makasih om jul 🙏
sama2
The pilot tied a red ribbon。 YA!
Your small videos are also as useful as the build videos. Can you please post a video on how to make a design for scratch built planes? It would be very well received by the audience. Also post videos of how you make your plans from which you make all your planes. Thank you in anticipation.
Wow
Hello, do you have any videos for cp, ac and np?
Mantap om! Next, jelasin cara cari thrust angle dong om! Thank you!
thrust angle biasanya tetap sekitar 2-3 derajat, abis itu disesuikan dengan kondisi saat dicoba, tapi biasanya 2-3 derajat sudah cukup.
Very good nice
Thanks
Excellent explanation for finding the CG in a very simple way....
Glad you liked it
@@JuliusPerdana i really love all what you show in your projects and other educational activities. You are brilliant.
@@JuliusPerdana at the same time, i m waiting for the remaining parts of the 747 built plans which you have not given in your videos. I don't know what is keeping you from sharing????
🤔🤔🤔🤔

"Nose heavy planes don't fly well, tail heavy planes don't fly long"
Very informative sir, well done!
Glad it was helpful!
Hi Julius, I just joined your Shareskill you put on description. How to find your class? Many thanks 🙏🏼
I dont have it, its my sponsor
Om Jul, saya mau beli MK18 pdf full version kenapa ga bisa?
Nice video 👍🏻and I really like that Skymaster I have one that looks exactly like yours, Only thing is when people see mine they ask why I have put a handle above the cockpit 🙄
hahaha yeah kinda looks like that
Plz can you make a dornier 228-202..
Kapan bikin kapal pesiar LG pk
Best of luck for next plane project
thanks
Ah, the secrets of flight!
How do you mark the cg point on the wing of the model
Thanks for this vedio. Cheers
using small screws, put it on the bottom side of the wing for high wing plane and on top of the wing for low wing/ middle wing plane
Sorry what i meant was how do you mark cg on the model's wing with the calculating software
I know I have asked this before but could you post the link for website you to make you planes
look it up on description
Gutt
Do you have to do this every time you change the battery??
CG location is permanent, once you marked it, it always stays there. But if change the battery (size) let say heavier one, you need to adjust the battery placement, to the front or to the rear but the CG location will not affected. The CG location will only be affected if you change the wing with different shape.
mantap nambah ilmu lagi 😅
Halo om
@@dewa_surya_adnyana halo juga 😅yuk jet2an
@@aerokambuhan skuy, tapi saya tes DAS 7 dlu :v
hi Julius, your diy plane projects are awesome n thx for the cg tips..on a pusher jet do they need to hv a thrust angle on motor?
depends on motor position relative to the CG point/ center of mass. If on the same level then no need angle thrust. If it higher, give a down thrust angle. If lower - up thrust. But if the motor far on the tail, no need
@@JuliusPerdana Thanks Julius 🙏🙏 i have been watching most of your videos, is creative diy..i don't hv that creativities to diy such plane like what you did
only what i see is you don't have a good flysite for your maiden..but you still get a good maiden fly 👍🛩️🤩
Which transmitter and receiver should we use to get max range of about 10 - 15 km
Pls tell
Pls tell sir
Sir pls make an RC plane having range of about 10 to 15 km using LoRa
wow, that's too far
could you explaine me, by text, how to mrasure MAC of tapered wing, and its CG. THANNK
Have you seen all the video, its all there
Om buat yang extra 300 nya om
Om reques plan pesawat wayang om.saya klo bikin yg kyk di fdio blm bisa nyetir ny🙏
cari aja di google, saya ga mau bikin kayak gitu hehehe
Omg make the extra 300 om
Please make an Antonov an 225
Can you make A6m zero, japanese fighter plane,pleaaseee.
ok 2022
Boss julos skilshere tu apa
Request Penjelasan CG nya bisa pake bahasa Indonesia bang 🙏🙏 thanks
Maaf om bantu sama terjemahan bahasa Indonesia.biar yg nonton diindonesia juga bisa ikut belajar.maksih
Really good explanation,but it is all done to fast,and also speaking to fast
Ga ngerti bahasa nye om saya.😭
at 2:44, ummm it is possible to BEGIN the process, with a guesstimate.!!!
for swept wing, around 45 percent of root chord; for delta wing, near 50 percent.
Ora ngerti bahasaneee😭
at 6:59, HORSCHETT this completely ignores the NEED to trim the stab/elevator.!!!!
make a LIST. okay cg, 25. normal cg, 30. swept wing cg, 45. delta wing cg, 50.
at 5:28, REALLY????? only a flying wing IS a flying wing.!!!! doing that will NOT give correct cg, for a conventional planform.! googletranslate
Best and most efficient explanation of finding CG ever. Thank you
Glad you think so!
