I quite disagree, although the observation of the videos provides useful information to take into account. The negative power (more red than green in the generation column) is related in several videos mentioning wind speed, mentioning wing speed and its variations during the loop, mentioning the two modes of flight, take-off and generation, and some other parameters, lead to the need to another architecture, or at least another plan of flight, not to mention the in-flight crash. The comparison above between M600 and Wing4e is talking: the smaller Wing4e works better. It is not an affair of software but a matter of wing loading.
Concerning the crash, I have not information enough to know the cause, so I would leave aside the assumptions expressed, which are nothing more than assumptions.
