DISCLAIMER
This video was filmed in accordance with EASA and ENAV regulations in a safe location after consulting government provided airspace maps.

Join me in this FPV mountain climb adventure which almost turned into a disaster.

Video feed is goggle dvr up until I lost video link, then it switches to the recorded air unit footage. Credits to Gal Kremer tool to convert the CSV data from opentx telemetry into viable SRT subtitles : https://kremerfpv.info/#subtitles

Watch my other video for a 9km long range test:
   • 9 Km from home long range flight with...  

Antenna used on goggles:
Left side: truerc xair 10db ( https://www.truerc.ca/shop/58ghz2/r... )
Right side: 2x prodrone.pl helical 12 turn 14 db ( https://shop.prodrone.pl/pl/p/PROHel... )

This configuration is a diversity setup, the xair has a very good beam range even on the edges, while the helical is a sort of "bonus" if you manage to point it right, giving you the extra "punch" in signal strength

Pictures of my gear (goggles, drone, radio): https://onedrive.live.com/?id=4E7DDD4...

Drone: Chimera 7 LR ( https://shop.iflightrc.com/index.php... )
Weight allout is 1.501 grams, no Action camera.

Motors: 4x Racestar 2508 AirA BP 1.200kv ( https://it.banggood.com/RacerstarAir... )

Props: Gemfan flash 7040x3 ( https://it.banggood.com/2PairsGemfa... ). I did some tests with the 7042 2 bladed props, they are a little more efficient, but are harder to balance and I haven't been able to avoid vibrations and jello with them, whereas the 7040x3 are very stable with no balancing.

ESC: Mamba f60 PRO ( https://www.diatone.us/products/mamba... )

FC: Mamba F722S blutooth ( https://www.diatone.us/products/mamba... )

Battery: 2x (in parallel, 8.000 mah total) 6s LiOn 4.000Mah, 21700 40A Samsung cells (https://www.farinsframes.com/6s4000m... ). Each battery weighs 440 grams.

BN220 GPS ( https://it.banggood.com/BeitianDual... ). Turn ON in Betaflight Galileo setting if you're in Europe, it really helps get more satellites.

JHE42B_S active buzzer ( https://www.banggood.com/JHE42B_SFin.... It's a must per long range drones, to increase your chance of finding it in case of model lost / crash.

Radio: Radiomaster TX16S ( https://it.banggood.com/RadioMasterT... )

JR Module: TBS Crossfire TX lite ( https://www.teamblacksheep.com/produ... ), set at 500mw (no need for 1W or 2W, LQ always at 99)

Radio antenna: TBS shapeshifter ( https://www.teamblacksheep.com/produ... ) , set in vertical position and in directional mode.

Receiver: TBS crossfire diversity nano rx ( https://www.teamblacksheep.com/produ... ) set at 8CH

Link antennas: 2x Truerc bardpole planar bazooka dipole antennas ( https://www.truerc.ca/shop/linearant... ) set at 20 degrees on the vertical plane, since most of the time i fly close to this pitch angle. One antenna in the front and the other in the back.

Video antennas: 2x tbs triumph pro (long range) ( https://www.teamblacksheep.com/produ... ). I have also tested the truerc singularity and they perform very similarly to the triumphs, get either one of them and you'll be fine.

Dji unit settings: 1200mw, 50 Mbit per second, High Quality, 4/3 screen, autofocus off, power mode on. I put an extra 30x30x10 5v high rpm fan above the air unit to help cool it down, i feel it's a need at this power output.

Betaflight main settings: 4.2.8 firmware
PIDS: multiplier 1.1
Filters settings sliders: 1.8 / 1.8, RPM filters ON.
ESC settings : 48 PWM, timings 11 (my tests with a power meter show that these settings result in 7% less power consumption compared to the standard 24 PWM / 16 degrees timings)
