Thanks, Campy,
One question-"slightly noseheavy" does this mean that at 30% of the chord, -the reference CG point- if the planes nose drops slightly it's ok? And also add no weight to the tail, move batteries etc, to compensate. I don't know why but I need some help understanding nose/tail heavy in relation to the desired CG point. If a plane is slightly nose-heavy is the cg point slightly forward of the desired CG or slightly aft of the desired CG? (In this case, 30%) Thanks again!
