5 Ways to Find CG (CENTER OF GRAVITY) of RC Plane

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

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

Hi Julius! Thank you so much for your videos! Don't stop doing them!

[carbonEYE]

Your channel is invaluable to the hobby.
Thank you for the tips and the time you have chosen to give to your fellow pilots

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! 👍👍

This is excellent! Really appreciate the practical and fast demonstrations and the delta wing tutorial was easy to understand.

mantap bang, , jelas skali penerangan👍👍👍

[felixsrcworld]

nicely done om jul. find cg on all models are very important..
Thanks for the tips oms🙏

[messybench]

Thank you so much Julius! Best CG explanation video ever!

[AmruMagdy]

Best and most efficient explanation of finding CG ever. Thank you

[fyzobaba]

Nice. this is the best cog calculation of all I have been watching! I subscribed buddy.

[tamilkeerthi]

Tons of appreciation for your effort. Please continue sharing such useful videos 🤠

[warrenmoy]

This guy so helpful. God bless you brother

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.

Hi Julius, I just joined your Shareskill you put on description. How to find your class? Many thanks 🙏🏼

[DwiAgungPambudi]

Mantap om! Next, jelasin cara cari thrust angle dong om! Thank you!

[RcAircraft]

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 🙄

[mirzawaseem]

Excellent explanation for finding the CG in a very simple way....

[Danial-ouxd]

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?

[thanuheenatigala]

How do you mark the cg point on the wing of the model
Thanks for this vedio. Cheers

Hello, do you have any videos for cp, ac and np?
