Catalyst Machineworks More Massive Droner 3", HGLRC F438 Stack, Brotherhobby Avenger 1507-4100KV Motors. Although i mainly use 4S Tattu 850mAh & 4S Tattu 4S R-line 850mAh Lipo's, this flies flawlessly on 3S Tattu 650mAh with Betaflight ver 3.3.3 Stock PIDS, i have no larger 3S XT30 Lipo's to try. The motors run cool on 3S and barely get warm on 4S with custom PIDS which im still in the process of tuning.

Non stock Betaflight settings:
Dynamic Filters On
PT1 D-Term Lowpass Filter
Gyro Notch Filter 1: Off
Gyro Notch Filter 2: Off
D Term Notch Filter: Off

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!

With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
