We are looking for a "Pusher" style airframe with twin booms, weighing less than 30 lbs with out any payload or electronics, engine, fuel tanks, etc.. We are looking for a wingspan of about 10-17' maximum. Want to power it with a 100-150 CC heavy fuel engine. It must balance out with in CG parameters, be able to carry a bout a 10-15 lb payload beyond fuel and crusie for at least 20 hours.
