This is my second whoop. This is my own buildup.
The motors are the 10000kv variant.
Weight without battery is 46g, with battery 75g.
First flight was done indoor and it was very good.
Outdoor performance: 26A with max throttle and min. 6 minutes flight time. It is stable and good to control. I used the Betaflight commuity preset PID setup for 2" - 3" Quad - 11xx-12xx Motors

Update: The happymodell VTX u.FL antenna connector was broken due bad soldering quality(BG send me an other), I decided to switch the TBS unify pro32 nano VTX. After the update weight without battery is 43g, with battery 72g. The VTX signal also better.

Update2: I switched back to happymodell VTX, and changed camera to eos2. The frame changed to cinacan 85mm and the radio to Fli14+ (pictures later)

Update3: VTX switched to happymodell diamond VTX and Foxeer predator nano 4.
