7" Source One Long Range

By SandroFTW on Nov 09, 2019

19 1,910 8

I was so annoyed by my long range wing that I wanted to build a quad.
This is my first build running EmuFlight. Even with that big battery it flies decently.

600g AUW (with props and gopro)
775g 4S4P 18650 10.4Ah

-> 1375g takeoff weight
~25min flight time

Edit 1 (18.12.2019):
Landed at 3.3V/cell (under load) after 20min.
I am going to try a 4S3P pack with 3500mAh cells to get the same capacity at almost 200g less weight.

Edit 2 (24.03.2020):
I upgraded a few parts and am mainly using it for freestyle flying:
FC: Matek F722-STD -> KISS FC V1
ESC: FETTec ESC 4in1 35A -> FETTec ESC 4in1 45A
Here are a few videos that were filmed with this quad:

(Beginning was filmed with a 10" Hex and the DVR was from my race quad)

That pack seems crazy, even to me - do you think there would be any utility in a lower weight (4S2P, 4S3P) setup for the same general idea?
I'd want to run a 4S1P pack up top, and 4S2P bottom mounted, and see what that could do, but that's new territory for me.

SandroFTW Nov 19, 2019

It flies with up a 5S8P 2kg battery but I'll soon be building a 4S3P with either VTC6 or Sanyo 3500mAh cells.

Nice. That just makes me want to go fly around with my 6S 5000mAh LiPO pack.

jdmkramer Nov 10, 2019

That pack is a beast! What cell are you using? I'm loving the benefits of Li-Ion so much that I'm trying to work on some smaller quads as well. If only there were high drain 18350 I could have a proper 2" Li-Ion build. Love the build as well!

SandroFTW Nov 10, 2019

I'm using Sony VTC 5 2600mAh.
Take a look at Dave_C FPV on YouTube. He is working on some cool longrange micros

jdmkramer Nov 11, 2019

Watching the micro long range video now. Very cool!

rossmoney Nov 09, 2019

my goodness gracious, this is definitely a dream build for me... wow, well done!

SandroFTW Nov 09, 2019

Thank you! I started to plan and improve the component list almost half a year ago.

Build a 5" Long Range Drone - Transformer Ultralight

Jun 21, 2021

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..

Build a DJI FPV Cinewhoop - QAV-CINE Freybott Edition

Mar 04, 2021

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..
