You were born an original don't die a copy.
Sir it's all because of your help. It would be great if you can PM me your WhatsApp number as I am now thinking of making a rc plane after a few days so definitely would need help.

@knvshrm,
Hi,
Saw your msg in Goli’s thread.
Here’s an easy method that can be understood from the attached pics.
Pic 1 shows unbalanced, ie, CG not at the centre of the quad
Pic 2 shows balanced by moving the lipo a bit towards the lighter side.
Repeat with the other pair of arms.
When properly balanced, all four legs will lift at the same time when you pick the quad up holding the centre of the string!
Hi sir i didnt understand how u checked CG with threads

Dude , here is an easier way to get the main Idea. The correct centre of gravity of a quad should be at the geometrical centre of the quad body. That is, the quad should balance at the absolute centre of the quad, just like balancing a scale.

Hi Pro,
Dont need no thrds man. Ven u no the CG, As you sd hr:
http://www.rcindia.org/rc-people/how-to-tune-p-i-settings-in-kk-2-1-5-fc-for-quad/msg286768/#msg286768

Nothing great in it. Exactly like a vegetable seller’s scale for equalising the weight on each side...
Have to do it twice though, once for each pair of arms. The lighter side will rise first when you pick it up from the centre of the thread tied to equidistant points on opposite arms...

@Iyer sir, I didn't mean to disregard you.
I think the OP doesn't know the need to balance a quad.

This is what he said:
“Hi bro i found the CG point on my quad....what to do next?”

That’s why I said no more need for threads (even though I was told it means clothes  Head Scratching)

Guess I’m just getting puzzled by Modern English, like I was with Modern Maths once...

He found the point where it balanced. It is technically the CG, but not the cg we want. Just like, if we put too much lead on the nose of the plane, The plane can technically balance on the nose of the plane

Technically the CG? What’s that?
The CG is the CG, that’s all. It’s where it balances.
Even if it’s not where you want it...
He said ‘What next?’
Perhaps you didn’t see the reply...

Can we let it go, please?
