The Great Curtis Youngblood suggested training gear balls of different colors on each side, bright colors or flourescent. It made sense to me. Just think, if from behind you go right ,and you're talking having say the green balls on the right. So nose-out you go right stick to go right,sure,but regardless of orientation going towards green would always get the heli going right.
Even now he said when practicing he'll have something on one side differentiating it from the other....wow ! Also I saw a guy with a really well done flourescent green on one side,orange on the other and man did that give a really good picture of what the heli's doing.
I should do that come to think of it.
My opinion is that if orientation is still something you're struggling with to the degree you stated it's not time to remove the training gear yet,either. Some will say'Oh, it weighs too much',etc. I say bunk.
Good training gear can save money,lots of it,while the zilion things to learn on helis is learned. Doug
