Probably. It makes sense to investigate the stability and control of a new aircraft shape and test it with a single channel Fly-By-Wire system, if that is necessary. It is a cheap way to look for problems. You may launch it from a tower and not install a power plant or a radio control. As a next step add power plant and radio control to an aircraft that is say twice as large in linear dimensions. The power plant may have been a pusher propeller type for the J-20 model.
