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

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
