mission6


The airframe is designed around the efficiency of the 8 cyl Lycoming engine the engine prop combination produces a balance of objectives that allows speed, service and the freedom of no  flight restrictions.

All skins of the Morrison 6 kit are made with 7781  e-glass prepreg and epoxy resin content of 36 to 38 %, vacuumed bagged and cooked at 250 degrees, plus the fibers in the prepreg stay in a straight line making for a stronger skin . Nomex core wrapped in adhesive. Designed for ease of assembly. Pre-cured graphlite carbon rod packs are built into the structure to carry the designed loads. The advantage of the rods is that the fibers in the rods are straight and will test out to the tinsel strength  designed.
