This has been bothering me for some serious time on scratch builds that don't already have a pre determined CG mark, thank you for finally making things easy to understand!!
I told MDD to balance the fuse on a pencil a couple of minutes after this very good vid came up.....nice one frogs84ss this shows him much better....keep flying
Video should be@ the top of search topic, gets to the point . COG is critical and I didn’t want to mess up my hard work. Fortunately had all my parts, was able to apply his tips asap. Simple answer to a hard ass problem to new “mini” aviators as I would hope to call it. Thank you
Even if you don’t have your parts. Try to look up weights of parts, find anything you can, I used as little as an eraser as a substitute for balance. Don’t give up. Take your time. It’ll be worth it’s time when you see your even masterpiece soar. Off that invisible force.
Nice looking version of the noob tube, if I'm not mistaken. I like it. Colors are good too, and I especially like the swept back vertical tail look. Gives the model a new aerodynamic perspective. I'm going to adopt that with my next build.
So After you place fuselage to balance on wing. Is that the exact placement for the wings position once on top to balance or will wing still need to move to find Co?
i have 3 pound airplane, push prop i need pick up motor and speed control which let me flight 30 to 45 min with 4 cell 5200mah battery, is this posible, and what motor and esc do i can use, some body help me
if it is a manufactured plane then by all means fallow there guide lines. and always make it on the nose heavy side due to tail heavy planes being nearly impossible to fly.( as you found out. again if i can offer any assistance please let me know
in this video I was kinda refering directly to the experimental airlines noobtube, however on a normal flat bottom airfoil wing the cg should be at the highest point of the airfoil provided it's a straight wing. if it is a flat wing like on a scratch build foam board plane or somthing similar then a good starting spot is 1/3 from the leading edge. sorry to hear of your failures. but on a positive note all that means is your learning what not to do. if I can help at all please let me know
on straight wing always or most of the time try 33% of the wing from leading edge going back example lets say the wing is 10 in wide you go 33% of ten or whatever the size of the wing is 11,1213, most of the time is 33%
It's all very simple. just look right here!ocw.mit.edu/courses/aeronautics-and-astronautics/16-01-unified-engineering-i-ii-iii-iv-fall-2005-spring-2006/systems-labs-06/spl8.pdf

Thanks for explaining it, helped me a lot.
So
After you place fuselage to balance on wing. Is that the exact placement for the wings position once on top to balance or will wing still need to move to find Co?
Finally some simple good explanation!!! thank you!
I use this type of cg for my rc plane like this model
I ask you one question can i use this method finger thumb of leading ege
A good starting point is the manufacturer suggestion. But you could also test it at 1/3 back from the lead edge of the wing.
How far can you put the wing back before it’s not flyable anymore
When i use this method it dispute the role of finger thumb of leading ege
hi very nice video! do you know where the cog (center of gravity) at a rc glider with no motor should be?
Would this work on a biplane? I am in the process of trying to build one and I am curious about how to find the CG on it.
That dog is so cute!
Focus man.
i like the skis can you do a video on how to make them.
Thanks, I have never seen this way. Thanks a lot. This way looks easy.
Excellent vid!!! thanks for sharing
thanks, I'm a novice and this helps for putting fpv on my apprentice 15e.
i have 3 pound airplane, push prop i need pick up motor and speed control which let me flight 30 to 45 min with 4 cell 5200mah battery, is this posible, and what motor and esc do i can use, some body help me
In actual plane, a thin person will have a different CG from a heavy person. How do engineer solve this problem in ultra light plane ( single seater)?
Great video thnk you for your tips, this simplifys COG issue
Hi, Good video, Will this formula work with a Delta Wing? I only ask as I acquired a A380 150cm x 140cm and the manual doesn't show CoG, Thanks.
no its actually kinda specific to this style of plane.
if it is a manufactured plane then by all means fallow there guide lines. and always make it on the nose heavy side due to tail heavy planes being nearly impossible to fly.( as you found out. again if i can offer any assistance please let me know
Great info. Thanks!

Helped me Thank you!!
How help explain me
on straight wing always or most of the time try 33% of the wing from leading edge going back example lets say the wing is 10 in wide you go 33% of ten or whatever the size of the wing is 11,1213, most of the time is 33%
Thanks... Nice & simple
Did you make that rc plane?
ricomajestic yes.
Good video...Thanks!
33% back from front fuse then place wing were 33% back from the leading edge lines up with the 33% mark on fuse and your done simple noob tube design
start at 30-35% back from leading edge of the wing chord. that WILL always get u in the air
And if it's tail heavy it will ALWAYS get it back down.
Great....tnx a lot
Thank you .
good
Nice techniques
30 / to the center fo gravity

it's not called cog, its only called cg :)
