Hey-

Has anyone ever come across any type of spreadsheet or online calculator that would allow one to estimate the trajectory of an arrow at any given distance?

I have no access to anything beyond 25 yards right now, but would like to arrange my pins in a 25, 35, 45 configuration. It would seem that there would be an equation that would allow a person to factor in an arrow's mass and velocity then determine if a top pin is zeroed in at 25 yards, the second pin will hit xx-inches high at 35 yards and a third pin xxx-inches high at 45 yards.

I know it can't be too precise without knowing all the variables such as surface area and angle of vanes, etc., but surely something out there can get me close.

Thanks!

Chris
