Rich,

I am normally only at most a hundred yards out. That's a guess but our area that we fly in is about a 1/4 mile stright out from the pilots stands and 150 yards right and left.

Color of the plane is important and is having a different color on the top versus the bottom. Allot of people have stripes, big letters, geometric shapes, etc... on the bottom. I have been told that geometric shapes are esier for the eye to pick up.

Size is very important. I started out on 40 size and now do mainly 60 size to 1/4 scale and I definitely find the bigger the plane the easier it is to see. Also big planes fly much better and handle wind easier.

I am also very near-sighted plus were bifocals and for me yellow seems to be the best.

Here is a good start on the subject...it's 2 pages but has good info on it. Just start at the top
