Glass vs. build up
how much weight could I save if I made a fuse of fiberglass as opposed to built up. I know the work is tremendously tedious, but what I'm looking for is finished performance. The model is a scratch built F4 phantom. roughly 58 inches long with about 45 inch ws. (measurements are rough because I may make some adjustments.) I am going to make ducting for DF version, and an interchangeable nosecone as the plane will be a propjet to start. when my thumbskill is adequate I'll convert it to DF.
the ducting in place will act as a cooling tunnel for batts and so forth. I have drawings that are fairly close to scale.
