Here my first frame design as a second build of it with some modification.

It is inspired on some light 3inch existing design and espacially the carnage V2 from Sub250gFPV.

The name of the frame comme from the fact that I think that the naked bottom plate does look like a frog.

I kept the idea of low KV for 4s 3Inh on the motor because the first version flue so well ! It keep the drone really silent wich is one of the main goal on that build.

The vibration of the build are great and you can find some info about the tuning and the black box below.

If anyone want to build the same the frame will soon be available. I'm currently looking on how to get it on cncdrones and other manufacturer. I also can share all the tuning parameters !

I show the picture with 2 straps but I usually use only one.

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..
