The following comments are made from observing Rollers that were top flyers at different lofts as well as my own loft. Please note this article is my opinion based on those observations. Feel free to E-mail me if you disagree. I know well, there are others with more experience than I. The wing should have long narrow primaries which slice through the air on the up and down stroke. These narrow primary flights are responsible for the rapid wing beats that give the spinner the hole. The last four especially should be narrow gauge the length of the shaft, this allows the air to flow around the feathers while the bird is performing the spin. One must be mindful that the roll is a backward summersault, and the wings are beating all the while the bird is spinning in a downward motion, thus the narrow flights to allow the air to flow by, not causing a lifting effect but a spinning one. Wide primary flights will act like a kite giving the bird upward thrust, causing not only a sloppy roll but one of lesser speed. The wider primary flights also cause undue strain on the pectoral muscles and wing joints. This is noted after a flying exercise with good rolling, the birds will land on the loft roof and those with the wide primary flights will be carrying their wings lower than their tails, almost dragging the primaries on the roof until they recoup.
Secondaries are also important in the overall structure of the wing. They should be shorter than the primary flights, and angled toward the body with the wing extended. The secondaries do not want to be to long, so when the wing is carried in the closed position they go over the side of back. I'm sure we have seen birds standing with the wings against the body, and the secondaries are standing up beyond the back. Kinda like a DA hair cut eh? All photos of champion flyers have a streamlined wing, with no break along the back and side. The only break which occurs in the wing is from a frontal view, that shows a predominate separation from the body at the joint, or as commonly called the wing butt.
Lets recap for a moment. Long primaries, the last four should be narrow the full length of the shaft. The secondaries should be shorter than the primaries and angled toward the body, not so long as to to overlap the body when the wing is closed, wing butts pronounced.
I feel the above wing condition and the overall body shape if in balance with the whole bird will give you a Class "A" Spinner. Take a moment and check your Best Roller and see how this article relates to the wing and overall stature of the bird.
Keep Look'n Up!
