This is an aerial launch platform that is relatively large and should be able to launch most aircraft. The purpose of her construction was to test the flight performance of various aircraft and the relationship with the aircraft. The original idea was to build a plane to test, and the result was a huge thing... at least the biggest plane I've ever done... the connection points can be placed throughout the fuselage for mounting the experimental load. But please do not affect the operation of each component.  Special Note: After carrying the load, please take a careful calculation of the changes in the center of gravity and mass center of gravity before and after the launch to prevent the aircraft from losing control and pay attention to flight safety.Finally, I wish you a good flight experience.
