Eye hand coordination
Ed, unfortunately I probably don't have the greatest eyes in the world when it comes to orientation. So, I make sure my planes help me out.
When I've had planes with poor visibility for orientation, more flights doesn't make it better for me, just more stressful, more difficult, more dangerous, and crashing is what tended to happen next, until I learned how to modify planes for improved visibility.
I do know people with many flights on their US60's and yes, they do fly it, and do get used to it, but still think the visibility stinks. Why not make it better?
RCPilot - yes, I had to add about 3 oz to the tail. This was split into 2 pieces of lead, covered in red Ultracote, and epoxied to either side of the base of the fin. You don't even notice them if you are not looking closely.
Color scheme is attached.
