#57 is very good. The bird inside the R is nice, but I would like to see maybe less detail in the bird kind of like the bird in #52. #58's R with circle around it would be nice to have as a second logo that we could put on our aircraft.
They look great. I don't know what it would look like, but could I see #78 with the circle around the R expanded to be around the entire logo. I like #77 and #79 and just want to see what it would be like with a large circle like what you have around the whole words.
