Adjusting COG

[DeGrizzle]

Hey guys, I was wondering how important having a perfectly balanced nano CPX is? Is there a good way to find/adjust the COG on this thing?

I would imagine that out of the box, it is probably pretty well balanced, but when my main motor wears out, I am going to be replacing it with the HH Brushless, which I am pretty sure will make the front end heavier. Without just adding weight to the rear, how can this be adjusted? Or maybe I am over-thinking this, and it's really not that important.

Any ideas?

i would not worry to much about it ... but a stretch solid tail boom would both add/move weight to the rear and increase tail authority.
I would not add any dead weight .. the lighter it is the better it flys .
.
From my little bit of experience with hellis they seem to fly best if the majority of the weight is close to the main shaft .
.
to check the center of balance try to lightly hold it by the rotor head .( this is the balance point ) and see which way it wants to lean .

Check COG with the top canopy pins and the blades straight is what I have been doing. Hard to grab the rotor head in the right spot. Adjust tail boom length to compensate.

this heli weighs 26 grams, and just about all of that is right at center...thanks to flybarless technology cg isn't as much of a worry, because the rotor disc is so close to the frame. stretching the tail or putting tape or glue on your canopy are the only ways to really affect the cg in a way that will be noticeable in flight, and even then, at this weight the effects will be nominal...
