iFlight DC5 HD - DJI FPV - 6S

The iFlight DC5 is finially finished! I bought this frame a while back and I never spent the time to finish it because I had too many other builds that I wanted to work on first. What drove me to finish this build is the new SainSmart Cyberpunk TPU filament I just bought for the 3D printer. According to SainSmart, this color is called Neon Cyan, but the pictures I took with an iPhone camera is not capturing its true color. It looks a bit lighter if you saw it in person. Because of new filament I had print some new parts to replace the original black ones that came with the frame kit. The only things I remixed is the rear antenna mount, GoPro 7 holder, and motor wire cover.

According to someone test, they claimed that the TPU housing that covers the antenna can affect the signal. I do not remember the details, but he showed some scientific proof and it also made sense. It might not make a huge difference, but anything helps. That is why I remixed the antenna mount and it does not have any cover the tips of the antenna. I end up hot gluing the antennas down so it is not loose, like what you see in the image gallery below.

The frame has a custom front and rear brace designed by JTR1 on thingiverse. He provides the DXF files, so you can send to a CNC shop to get cut for about $20.

I do not plan to use a GoPro with this quad because the DJI footage is good enough for me. However, If I wanted higher quality video, it will be very easy to install the GoPro mount to the top of the frame.

The remainder of the build is very straight forward, and no modification was needed. This frame has a lot of restate so, I did not have any trouble finding space to put any of the electronics.

This build is an absolute TANK!!! I hope it is as durable as it weighs.

Betaflight Setup

I used all stock PIDs but use the BF 4.2 Presets:

HD (smoothed FF for HD cameras, strong low turn rate smoothness, low iterm relax to minimise bounce back)

set iterm_relax_cutoff = 10
set rc_smoothing_auto_smoothness = 20
set ff_interpolate_sp = AVERAGED_3
set ff_smooth_factor = 40
set ff_spike_limit = 55
set ff_boost = 0
set feedforward_transition = 40
set yaw_lowpass_hz = 70
set throttle_boost = 5
set throttle_boost_cutoff = 10
set dyn_lpf_dterm_curve_expo = 7
set gyro_rpm_notch_q = 800

To enable dynamic battery sag compensation:

set vbat_sag_compensation = 100
set vbat_pid_gain = OFF

Great looking build, I really like the camera mount print. Any chance on a link to that bad boy?

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..
