Here is a link to a 3 minute video showing some construction details and a flight.
The aluminum frame is a Dollar store level ($1) at 2 oz. Turning is done with a servo pulling wing tip lines down, pitch is by motor speed. Motor is 28x34 outrunner with 11x5.5 prop from headsuprc. Canopy is 1.3 meter. This is not my build, the builder and pilot is my friend Lionel.
