RE: My Byron CAP-21 mods
JeffH, I have never weighed it all, until today after reading your reply. The first weight of 7 lbs 9.5 oz is the airframe with all the radio gear, minus a throttle servo. It is also missing a pilot, and is not covered (Monokote) yet. My second weight of 5 lbs 9 oz is the landing gear; and all the engine stuff, minus a prop, a muffler, prop adapter, velocity stack and mount. My third weight of 11.3 oz is the fuel tanks, and smoke pump.
That puts me under 14 pounds lbs right now. I guess that foam is heavy, but I think I will keep it under 20 pounds. Thanks for the heads up.
