Anyone has a cowl please add the data point for weight. What color , pink, green etc.
Anyone with canopy skirts add data point for weight too.
Tail and wings really isn’t much weight, Carbon saves 15%. A possible 1.5 lbs to be saved on tail/wing. I agree it all adds up, but some may be more effective than others.
Con
Fiberglass is required on wing tips if you use an archer antenna. At 15% weight savings you’re trading 22oz for the loss of ability to use an archer antenna.
Possible Pro/Con
Effects of reduced weight of tail parts and more/less counter weight required? Perhaps someone could answer if you’d need more or less counter weight.
Cowl might be the most beneficial part to make weight savings. I’d assume it’s a substantial weight so a few lbs might be saved on the nose where CG effect may be an advantage depending on your configuration.
