Summary of what modifications I have done to the Bixler so far. This is after one week of flying with this plane, also it happens to be the first plane I have ever owned or flown (toys not included).
Short and not exlusive summary;
Two Gyros, Stiffened fuselage, hinged control surfaces, larger propeller, rubber band retention of main wing, camera mount, ESC cooling with air duct.
Hope this helps you.
