I had some spare parts and wanted more punch than my usual 2s drones, therefore I present the 4s 40mm "angry bird"!
Motors: T-Motor M1104 with Gemfan 1636-4
4-in-1 AIO: Jhemcu GHF435AIO 20A
VTX: Happymodel OVX303
The blue stuff on top: ummagrip lite, you almost don't need a battery strap anymore!
This bird is so aggressive, you basically can here the props fighting to stay alive. Needs some tuning though, the propwash is horrible.
EDIT: Forgot to add, I am using 2x 2s chained batteries (either 450mAh LiPo or 720mAh LiHv). Managed to kill one LiHv on the second flight due to an unlucky crash due to prop wash.
