Why did you "put" 50 at the tail ? You didn't put #50 there did you ? Why did you part out the 120, do you plan on carrying a two part person ? The scale reading increase at the tail is a "result". Simple math Wt x Arm = moment. Total moment/total wt=arm (orCG). Were you sleeping during W&B class ?
