is there a way to determine the CG of an unbuilt model design without an app like RocSim?
Oh, yeah, I will. It might fall under the "what the f- was I thinking" category, but what the heck.Originally posted by cls
you guys are right, it's easiest to just build it and balance it on your finger and add noseweight as required...anyways greylensman, want to post pix when you build whatever it is you are building?
Fact is you could sy6nthesize it, either on paper or with stick-and-weight modeling. But you'd have to know not only the weight of each piece (or collection of identical pieces, such as fins) but also THEIR CG, so you'd know where to place things on the model/weights on the stick.Originally posted by graylensman

Exactly! I know I could just stuff a bag of lead weight in the nose and it'll be stable, but the model would probably stagger fifty feet into the air and fall like an anvil, even with a chute.Originally posted by DynaSoar
The more I build big birds with heavy duty MMTs, the more I'd like to be able to model CG first. I prefer to not add dead weight.
