Calling all physics majors,
I'm wrestling this big 27% scale plane on and off the balancer with the help of a friend and I'm a bit nose heavy. I stack 2.5 oz of weight at a distance near the tail and it balances. Now, instead of adding more weight to the plane I start shot-gunning some new servo and battery pack mounts rearward of the canopy thinking I'm going to balance. Trouble is, will I get lucky? It's been awhile since my physics classes in 79.... does anyone have a formula for mass versus moment. I should be able to put a calculator to this and get the radio position in the ball park without calling my friend over each time I balance. Yes, I've got a sweet digital scale.
