This is a nose gear brace for the Freewing 80mm A-4 Skyhawk. It will give the nose gear extra support for rough landings and fields. The plastic nose wheel well cover needs to be removed to glue this brace in place. I use mineral spirits to dissolve the glue that holds the well cover in p lace. I also use the included rubber cement to glue the brace in place. There is very little clearance between the steering arm and brace so make sure that the nose gear steers freely before the glue dries.
