The Frog 3inch

Here my first frame design.

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.

The flying is amazing.
I choose those parts mainly becose they are scavange from my 4inch Diatone roma L4. The low KV motor makes it very fly efficient. I can go for 6minutes of light freestyle on a 450mAh 4s.

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

The 3d prints models will be posted on Thingiverse soon.

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..
