I got hooked on this:
Group of dedicated ( Nico, F, T )
Fits into IOT/Hardware strategy ( RemRea )
Pulilab and the drone-business. ( Agriculture )
Pulilab & Drones
Camera drones ( dji, gopro )
Delivery drones ( amazon, DHL )
"the dark side" ( chainsaw + gun + military )
and FPV drone racing

Drone Racing explained:
- Quadcopter controlled in First Person View.
Getting started with your first Drone Racer
- Buy hubsan X4
- COMMIT ( or leave while you can )
- Research, research, research!
- Buy reusables. ( radio, goggles, charger... )
- Buy parts ( always buy one extra of everything )
WARNING!!!!
Getting Started
Skills needed - soldering, fine mechanical flair...
Where to buy - banggood.com, hobbyking.com, eud.dx.com, n-factory.de

Yays! and nopes!
A quick guide on how to survive this hobby
So what is a drone...
... let's ask my grandma!
- Four to eight powerful motors
- A sturdy and hard body
- A clueless guy issuing orders
- Four to eight blad..propellers
Grandma: "Easy, it's you using a BLENDER"
A flying blender...
Flying blender...
... My grandma blender properly used prepared tasty smoothies...
...Our flying blender properly used can provide hours of endless fun!
And soon used to deliver pizzas.. Mamma mia!
Common Nopes
Attitude nopes
Planning nopes
Building nopes
Configuration nopes
Planning nopes
- Buying parts without checking their compatibility
- Forgetting to buy spares
- You will need accessories
- Skip reading the manuals or ask for help... sempai! ( I meant drone daddy.. )
Building nopes
- "No problem I am putting that thing outside of the frame"
- "Let's connect the battery WITHOUT triple checking all the polarities!"
- "It's just a quick indoor test.. I will not remove the propellers"
- "Pst.. ehi kid.. ehi you! Carbon fiber is a conductor"
- "Props direction.. ah! I know better, I put props on drone since 2 whole days!"
And yes, (I) we did all of those ;)
Configuration nopes
- "Failsafe, wow cool I will turn it on without knowing what it does"
- "Motor mix, sounds fun, let me fiddle with this a bit"
- "I built the FC rotated, I was told that I needed to do something else.. whatever it will be fine"
- "Wow look at all those switches in the configuration, AUTO LEVELLING, dang it should be ON"
Do one of this, and oopsie you have a fireball.. and you were trying it indoor weren't you ?
Attitude nopes
- "Let me hold the drone nearby the propellers, the arm switch is.. OUCH"
- "My buddy is flying FPV, let me connect a new battery... "
- "Oh look a river, lake, sea, It would be cool to fly over it! "
- "Battery warning? Who need that!"
Crash and accidents are normal at some points, but let's always keep our brain on!
Yay time!
Fly with company
Build with company
Record your flights
Stay active and enjoy nature (with
company!)
Fly with company
- You will have a spotter
- There will be somebody to watch after a bad crash
- You will give and receive tips and help
- Drones loves to play hide and seek in the grass after a not-conventional-landing, playing 'seek' with some buddies is much faster
- Add booze and snack for added fun
Build with company
- Remember? POLARITY TRIPLE CHECK!!!
- Another set of hands can be really helpful
- It's so fun to see your buddy's scared face when you do your first test flight indoor!
- You will be either teaching or being teached, there is a lot to keep in mind and know and with two people it is much easier!
- Your buddy may have a spare that you miss.. otherwise you can always raid Drone Daddy stash :D
- Add booze and snack for added fun
Record your flights
- It's hella fun to watch your flight after
- Records will be really helpful to PID tune
- You will be able to see how near slamming your drone to THAT tree you were
- Actually rewatching yourself help in learning as well
- You will be able to justify to your girlfriend / wife / mom / boyfriend why you got home all muddy, with torn clothes and with a smile that would suggest... outdoor fun ;)
Stay active!
- According to my phone when I go flying I double my daily physical activity time
- Exploring new places for flying spot is great
- After hours of building in a lab - cave - room being out in the nature feels great
- Nobody runs faster than a droner chasing a dog that decided to play fetch with his crashed quadcopter
Thank you!
