During many years of kit building I used RC 56 to glue canopies to bare wood, Coverite Permagloss covering and Hobbypoxy painted surfaces with success. If it takes a long time to dry and turn clear you may be using too much.

With newer ARF's I have had very little success achieving a durable and lasting adhesion between the newer canopy material and the covering on the airplane using RC 56. It just doesn't hold up under the high stress 3D mileage that I put on my planes. Screws work if you use enough of them with RC 56. For me, durability comes first, "pretty" is secondary.

Lately I have been using Fletch-Tite. That's the stuff used by archers and arrow builders for bonding feathers and plastic vanes to aluminum, fiberglass, carbon fiber or wood arrows. The company's name is The Bohning Company, Ltd.

Ambroid makes professional quality fletching cement for major manufacturers but I have never seen it anywhere.

Does anyone know from experience how well Zap-A-Dap-A-Goo keeps a canopy stuck to Oracover?
