What type of machine or technique are you guys using to find your exact C.G. On these large heavy planes...?

Thanks..

This http://www.rcuniverse.com/forum/tips...g-rig-how.html from foamy to super giant scale it is flawless. You still need to know where the CG is supposed to be based on plans or kit specs but it will show you where you need to add or take away weight to reach the correct cg.

I also use the Vanessa Rig. It is perfect for showing where the CG actually is and then I can move components around to meet the desired CG location.

Thanks guys for the input.. Doesn't look like many people use the CG stands. Is it because of price, user friendliness, or accuracy..?
Thanks again,

For me it's both safety & user friendliness. There's no lifting of the model onto a stand, the Vanessa rig does the lifting.
It's not a balancing act.


I have a fixture in the ceiling so I can assemble my models on their wheels, hook up the CG rig, then winch the model just
clear of the bench. If it were to slip (they don't) it won't fall far. You can lift the model from loops under the wings or fuselage,
whatever's easiest.

If the Vanessa rig was painted purple you would be paying hundreds for it!

I'm sure the CG stands work fine & are also accurate, this just works better for me.
