ok i'm totaly lost and need help on cg. i know it's critical and why, guess what i want to know is are there warning signs when balancing? i.e. your putting an arf together and using all the equipment the manufacture calls for, correct size enginge/motor, servos, retracts etc etc, then when you try to balance it needs 10 oz's of weight added to the nose, you've already moved things around in the fuse but still won't balance out, when do you draw the line at adding weight and start looking at the cg? or is it a personel preferecnce? i've read on other threads where someone has added 1lb of weight to the nose or 5oz to the tail. i know this is probably covered on another thread and if someone knows which one?
