while the drafting supplies were out, I thought to go ahead and finish drafting the fuselage plan. I chose to go with a profile, some frames, a few doublers, and shaped skin; all made from MPF foam. Then I estimated the weight. It looks like this.

Fuselage-31.2 g
flying surfaces and the booms-35.9 g
that puts the dry airframe at just over 67 g or 2.4 ounce

two motors, e-flight 180 Park with connectors and shaft keeper-23.2 g
receiver-4.6 g
two speed controllers with connectors-23.6 g
a Y connector for the controller-4.6 g
a hefty 7.4 V 800 mAh battery-43.4 g
three, 5 g servos (because I have them)-15.3 g
figure in 20 g for pitch horns, wire, glue

the job totals up to about 136 g. So altogether, I'm looking at about 204 g or 7.2 ounces.

With the two motors I'm planning, it should have almost 3-D performance.
Dad gum it! This thing will fly, even if I have to make it hang on the props.

If nothing else, I'll scale it up 30% and transfer the components to a larger airframe.
