Components used in this build :

  • Multicopter Builders Cinematic 7 (frame)
  • JBF4 v2 AIO FC
  • Multicopter Builders Primo 2208 2150kv motors
  • Flycolor X-cross (50A) ESCs
  • Foxeer Predator Mini v3 camera
  • TBS Unify Pro HV VTx
    • originally I installed AKK Dominator VTx but the built-in microphone was faulty so I swapped for TBS Unify and added external microphone
  • TBS Crossfire Diversity Rx
  • TrueRC Singularity Long SMA antenna
  • Beitian BN-180 GPS
  • Hellgate buzzer Duo
  • External microphone

I'll be using following 7inch props :

  • Gemfan Flash 7040-3
  • HQ 7x4x3
  • DAL T7056C-3

I normally use CL Racing F4S on all of my builds but decided to make an exception for this build and instead used JBF4 v2 FC, it's basically identically designed flight controller (even using the CL Racing F4S firmware) but it's rated up to 240A and probably more suitable for this setup with 7inch props running 2150kv motors on 6S batteries. One major disadvantage is the fact that JBF4 comes with no SD card reader for the blackbox, instead only onboard dataflash memory is used and at 16MB it's not very usefull (it can record only one 5min flight before it gets full and then it takes 15 minutes to download the log file).

AUW with GoPro Hero6 and 4200mAh 6S Li-Ion battery is massive 1100g.
Built as a long range surfer it's actually reasonably agile quad even on a tight track.

Batteries :

  • Home built 4200mAh 6S Li-Ion (21700 size cells)
  • Gens Ace 4500mAh 60C 6S (no way this is 60C, I would rate it 5C at best)
  • Swaytronic 4000mAh 35C 5S
  • Bonka 2200mAh 75C 6S

Awesome build! I saw your Matterhorn video on r/multicopter and was blown away. I want to use this frame for my next build and will probably use this as a reference.

Question for ya: What is that second antenna next to your video antenna for? Looking at your parts list I think its for your GPS, but I’m not sure.

not possible even if I wanted to, I lost this quad 3 weeks ago in Italy :(
I know exactly where it is, will try to recover it next summer, the remote area was not accessible due to new fresh snow and avalanche danger.

Fallkon   Feb 04, 2020 

wow that's pathetic

BigBeard.fpv   May 17, 2020 

oooh no :( - I hate when that happens.

Pete, could you build me such a quad?

Chrojo63   Apr 21, 2020  

Love everything about this build and I'm trying to do something similar.  What is the 2nd antenna in the rear?  I only see the SINGULARITY 5.8 (long) mentioned in the build list.

the other "whip" antenna is secondary Crossfire Rx antenna, home built. I'm using diversity Crossfire Rx and that takes 2x Rx antennas

Mickswagger79   Dec 30, 2019  

mate do you have INSTAGRAM?

fmcprogrmr   Dec 03, 2019  

Beautiful build! I love seeing excellent build quality. Are you happy with the performace of your home made antenna? Thinking about making some for my Slim+ receivers.

Awesome build!
How does it fly with
4s ?
Just  bought 7 inch frame.
Stamina endurance 7/8 inch
I have ethix konasty

is it to high kv?
I have som 4s 4/5000 mah.

Amazing build. I live in the mountains and want a drone that can handle the intense climbs. Would you be willing to share the files for the 3D printed portion of your build?

This girl is gorgeous, what ive been looking for is that RX long whip antenna you have out the back. ive been looking everywhere and cant seem to find it! can you let me know where its from please. thanks brother

pete_oz   Oct 18, 2019

This is a SICK build! I have recently orded parts for my very first build. Its going to be a 7inch meant for long flight times and high efficiency. The motors I order were the Race star air A 1200kv. Do you think this is to low and how you you think they will preforme? Many thanks

pete_oz   Oct 03, 2019 

well, everybody has different preferences, most pilots prefer lower kv motors on 7inch setups, for me 1200kv would be too low even when running on 6S, I just prefer performance orientated setup even at the cost of efficiency. it also depends where you want to fly, if you fly in the mountains then it's better to have more responsive (higher kv) drivetrain to fight wing gusts and turbulences.

Attention to detail coordinating your print colors with all your other accessory colors is second to none sir. Good lookin'.

"no way this is 60C" :)
you only want the r-line from these people. everything else i have tried is junk or becomes junk in less then 3 months

pete_oz   Sep 28, 2019 

sounds about right. I'm now using it only to charge other batteries with it on the field

Thomaat   Sep 28, 2019  

That 4200mah li-ion, is it a 6s2p?

pete_oz   Sep 28, 2019 

it's 1P (just 6 cells in total), weighs 430g

This guide will walk you through the process of building your first FPV quad. The goal with this design was to build a low-cost, lightweight quad, yet powerful enough to safely carry a GoPro in close proximity areas. I chose these parts to minimize the amount of soldering at no cost to the quality. A typical build requires around 30 solders while this only needs 25. It's not a huge difference, but..

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..
