New Build: iFlight DC3 HD – 3 Inch HD Racing Drone

I think this may have been my first build which I started and completed, and successfully maidened in one day. I’ve wanted to have a DJI HD FPV based quad that was smaller than the two 6S 5″ quads I currently have. Something more portable, and able to fly in smaller areas.

iFlight DC3 HD Frame

The frame is the iFlight DC3 HD.  DC stands for “deadcat,” which is an arm design which results in the camera having no props in view.

Deadcat designs are what many cinematographers choose.

FPV

I’m hooked on DJI’s FPV system because of numerous reasons, including the clarity of the FPV view in the goggles, recording HD 4K video on board, and elegant interfacing. So that’s why I chose the system for this build.

Receiver

For my receiver I’m using TBS Crossfire.  I’ve seen the light with TBS Crossfire and its long range capabilities.  I’ve essentially vowed that from now on I will be using Crossfire for all my builds.  This small quad has Crossfire, as well as the Immortal T antenna.

Motors/Power

I’ve been testing out some EMax motors recently.  I decided to go with the Emax ECO Micro Series 1407 motors at 2800kv.  Based on that one might guess that I decided to run the system on 4S battery power.

Currently my battery of choice is a CNHL 4S 650MAH.

Stack

For the flight controller and 4in1 ESC I went with the Diatone Mamba Stack F405US MK3 Mini F35.  I have a couple of other Mamba ESC’s in quads and I’ve been satisfied with their performance.  The stack is capable of running 6S.

3D Printing

I found some arm bumpers/motor soft mounts online to 3D print.  I also designed a 3D printed set of mounts for the Crossfire Immortal T.

I went with orange TPU filament to go with the orange theme of the quad.

Flying

I’m about to do some real flying with the quad in the next few days and will post some performance comments, and flying videos soon. Overall I’m very happy with the build and the equipment choices.
