Our 40% aerobatic plane cover will fit a wide variety of model planes. This cover will provide an acceptable fit for planes with a wingspan of 114"-122" and a fuse length of 104"-109". Our covers are designed to fit the shapes of the popular aerobatic planes. They provide a nice fit on many of the Edge 540, Extra 300, Extra 260, Extra 330, Slick 540, MSX, MSXR, Sbach, Yak, Sukhoi and other designs on the market. We all know how the sun can damage our planes. The cowl and canopy areas can warp and become distorted, ruining the overall look of the plane. Those are not cheap parts to replace, so using a plane cover to protect those areas and keeping the covering free from wrinkles is a good idea.
