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

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   11 days ago 

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.

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.

pete_oz   15 days ago 

thank you. that antenna is my 2nd crossfire Rx antenna because I'm using diversity receiver (it takes 2 antennas, I'm running 1x immortal-T and 1x home made whip antenna)

Cool! that makes sense. How good is the audio signal long range? Do you feel like hearing the motors helps you fly or do you simply enjoy the immersive experience?

pete_oz   11 days ago 

when the signal is weak the audio signal breaks similar way aa video signal can break. anyway it does help to hear the motors, especially when running Li-Ion battery and sometimes I would just forget to back off little bit if I didn't hear the motors.

"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   16 days ago 

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

When the FatShark HDOs hit the market in 2018 the FPV community rejoiced for the new Sony OLED displays. While they lacked further upgrades like an updated DVR and power button they were still a market success. With the 2019 announcement of the Orqa FPV.One the community finally had a potential HDO killer on the horizon. With only weeks before the release of the Orqa FPV.One Skyzone came out of left..
