This is my first whoop. It is based on Snapper7, but the frame is modified to Mobula7 v3 and I made an antenna modification to get better signal and added a buzzer.
Weight without battery is 29g, with battery 42g. Flight time about 4 minutes.

Upgrade: replaced the motors with 3BR-0802 18000kv. This motor is lighter, but stronger than the happymodel 0703 19000kv motor. The Weight without battery is 25g, with battery 38g with the snapper 7 propellers. With the mobula 7 propellers it is 3g more weight.

Upgrade2: propellers changed to gemfan 1636x4. The current weight is 27g.

UPDATE: sold
