Hello,
We have seen, in several videos, that the actual weight of this drone under 250 grams is much discussed. I think that the goal for this category and weight of drone, is the fun that can be ensured even in just 15 real minutes which are, in my opinion, more than enough, considered a VLOS flight. So, to solve the problem of high temperature and be 249 grams on any scale, you could reduce the weight of the battery by integrating a small cooling fan. Even though the battery housing closes almost hermetically, the battery can be designed with side cuts for air circulation. 2 problems are solved: temperature and weight.
This update, it would be the TOP, the number one of the drones under 250 grams with detection sensors and integrated cooling fan
