Gotta love how their flight control board is the same size and mounted to the back of the ESP32 module.

Edit: It references ELRS but I don't see one of the standard Lora tower antennas used in the smallest commercial modules. They also often use an unshielded esp32 Soc instead of the full module.

   The onboard embedded system is based on an ESP32-S3-WROOM-1-N16R8 (dual-core 
  32- bit Xtensa LX7, 240 MHz, 16 MB Flash, 8 MB PSRAM), supporting parallel 
  real-time wing actuation and wireless communication with a custom ground 
  control station for data logging and monitoring. . . . and an LDO outputs 5 V
  to the ExpressLRSmodule. The ELRS module serves only as a safety override for
  manual control.

Fig 1 showing the weight broken down by components is interesting. I would have expected the battery to be a larger percentage of the weight.

It's not the best, but there's a photo of the butterfly in Figure 1(B) on page 20.

On a separate note, if you're looking for something more explicit, there are some suggestive violin plots in item F in the same figure, ironically with the caption even saying "Nymphalidae" (here referring to the family of butterflies, but "nymph" is also a general anatomical term/prefix for female genitals, or particularly the inner labia or clitoris).

Nor a video. So many words though.
