The Camp Man Series: THE BUILD – Episode 3

Here is Episode 3 of The Build Series. All this footage was undertaken in Kununurra, Western Australia. We had the Manta Exhaust sent to Ord Mechanical Services to be fitted (OMS). We also had Coupletec Rustproofing & Enerdrive send us their products as well which were all fitted at our camp site at Lake Argyle Resort.


Manta Exhaust:
3″ with High Flow Muffler

Couplertec Rustproofing
Heavy Duty Kit

DC2DC Charger (30amp), 1000w Pure Sine Wave Inverter, 40amp AC Charger

Let’s Build: Small-ish Airship, Part 2 – From the Depths

What was I thinking…

BorderWise Discord:

Outro Music: Different Heaven: OMG:

Other music used:
Frank Rawel: Up_and_Down
Bastion OST
Transistor OST
Sang Froid OST
Age of Mythology OST
Tchaikovsky – Waltz of the Flowers
Doug Maxwell – Baroque Coffee House
Dan Bodan – Bike Sharing to Paradise
TheFatRat – Fly Away (Instrumental)

In From the Depths you can build and take first-person command of battleships, planes, submarines, space ships, hot air balloons and more! The game is currently in alpha and contains a wide range of single player content including:
A creative mode allowing you to push your designs to the limit and ensure the total annihilation of your opponents.
A campaign waged over hundreds of islands against eight unique factions.
A Story Mode where you can (eventually!) play 15 missions as each of the eight factions – a fantastic mixture of strategy, design and wild battles! Defend your fleet against waves of enemy forces in a series of extremely tough challenges that unlock new components.
An expansive multiplayer and co-op element is planned for the coming months!

Key Features:
Design and build your fleet, fortresses and structures however you want. The alpha currently has over 400 unique components blocks, not including 29 different components for making missiles, torpedoes, depth charges and bombs.
The sky’s the limit, you can equip your vehicle with – cannons, lasers, mines, bombs, missiles, torpedoes, propellers, rudders, jet engines, wings, hydrofoils, hot air balloons, anchors, fire control computers, blueprint spawners, repair bots, air pumps, automated control blocks and many, many more!
Realistic physics – every block destroyed or added affects the vehicle’s functionality, physics and control. Drag, inertia tensors, buoyancy and sealed compartments are all updated based on the design of your vehicle and the damage sustained.
Be part of a fantastic community: (, with new releases made on average once a week. Community organised challenges and blueprint sharing make it an extremely friendly place to hang out!

Customisable Components:
The customisable components in From the Depths allow a unique level of engineering customisation:
– Design custom missiles, bombs, depth charges and torpedoes by combining various warheads types, fuse types, IR seekers, laser beam riders, laser designators, thrusters, navigation algorithms, fuel pods, sonar seekers, buoyancy compartments and propellers, to deliver a truly bespoke weapon.
– Design custom cannons by combining four different barrel types and lengths with autoloaders, warhead types, ammo boxes and auxiliary components to create everything from AA cannons to howitzers.
– Design custom AI by combing an AI mainframe with ‘AI cards’ slotted into motherboard blocks. Add radar detection, laser detection and tracking and local weapon controllers to give partial or full control to AI. Create anything from a fully AI controlled aircraft carrier to a battery powered drone.
– Design custom engines using crank shafts, cylinders, carburetors, super chargers, exhausts and fuel injectors. Electric engines, generators and chargers are also available for backup power supplies and drones.
– Similar systems exist for the creation of anti-vehicle and anti-missile lasers, as well as drills that can cut even the largest of battleships in half.

LiPo Battery explosion prompted me to build a self contained PORTABLE Charging Station.

At least I tried SOMETHING which is better than nothing! When the LiPo Battery exploded in my charging bag, it burned the wires and also fried the charger! (See this example video courtesy of Rajucam Aerial Services) Therefore, I decided to make a safer and easier charging setup, which I call my LiPo Charging Station. Always be aware of how and where you charge your LiPo batteries and let this be a reminder that LiPo accidents can happen at any time to anybody. The above video link shows exploding batteries in different containers. Pay attention to the 6s test, as it is dramatic and what happened to me. I have no faith in charging bags anymore and am glad I had the charger atop a ceramic tile. Smoke was definitely a problem though. When it happened I was immediately on top of it with a fire extinguisher and got it out immediately. Note about my new charging station, I have small holes in the tool box lid to relieve pressure and am also planning to add a fire extinguisher inside that goes off if a fire. Be safe.

We recommend the new HGLRC 28Amp DSHOT Escs for your build.

HGLRC 28A DSHOT BLheli-S Escs. ( You need 4 ) Again I buy 5 in case I burn one up flying. So I have a back up.

HGLRC 28A DSHOT BLHeli-S Esc link:…

NOW to choose an “AIO” or “All in One” flight controller.
We recommend the HGLRC F3 Vers 4 because it has a built
in voltage regulator, OSD, Betaflight, Buzzer, and PBD. And it’s under $60. Also very easy to solder up as shown in the video.
