Wow, this is an amazing first FPV drone build! It's impressive how you've thought about portability and the practical limitations of flying in Germany. The choice of using two 1S batteries in series to create a 2S setup is a great way to maximize convenience, and being able to charge on the go with your power bank is super clever. Your attention to detail, like making adjustments to the frame and taking into account the components you already had, shows a lot of ingenuity. The fact that you're sharing these tips and insights will definitely help others with similar builds. Keep it up – this is some solid work!
That sounds like an incredible upgrade! Converting the Firefly 2S Nano Baby 20 analog to the DJI O4 Lite while only adding 1 gram is a great achievement. It's amazing how digital FPV has evolved to fit into such a compact form. The lightweight design and impressive flight time with the 660mAh GNB LiHV are definitely game-changers, and it's great to hear that the drone remains resilient during impacts. It's always awesome to see how technology keeps pushing the boundaries of what's possible in this hobby. Keep enjoying the flights – sounds like you're really making the most of it!
I have all the parts for this build, but what canopy is this? Please, point me to the right direction!
I think I used this one:

The model is a bit rough but it does well.
Looks good! How complex was the tuning, do you have a preset?
The user is purchasing Happymodel EX1102 10000Kv motors, citing their comparable stator volume to the HGLRC Specter 1003 10000Kv. This likely relates to a drone build or modification, prioritizing motor performance and size compatibility. I wonder if they're using this drone for recording videos of playing Monkey Mart game.

Nice build! motors a tad too big/heavy for my liking. I really like frames designed by LeDroneClub
checkout my builds, got a couple from LDC as well.
Did you publish the files for the hatch and pan/tilt anywhere? :-) My Nano Goblin has been collecting dust for some time, this looks fun!
It was great to see the replacement and upgrade process go so well Poly Track and the results are something to be proud of.
It's great to see you're passionate about FPV! Converting your Firefly 2S Nano Baby 20 analog Sprunki Mod to the DJI O4 Lite is a worthy upgrade.
I switched black dampers for yellow dampers and that is almost perfect, no more jello and the o3 recording is very smooth. I noticed better results with 3 blades props. I'm currently mounting an o4 lite for trying.
Yep, ATLAS 4 team!
On mine with original O3 antennas, Flash 1804 and a 4s 3000mah 18650 I can go up to 5Km. The limitation is flight time.
To save weight I will soon use 1404 3500Kv from happymodel. In fact, these motors are much too heavy and powerful for P30B Li-ion cells (36A max). I scaled down the throttle to 78%.
The Sony VTC6 only supports 30A peak, be warned or you will destroy them!
Maybe put an o4 lite to save more weight later, but the O3 is so clean and the wider view is a must compared to the O4 lite.
I can share my Diff if needed (3 bladed props)
Enjoy!
Thank you for your comment. I also suspected the 1804's might be a bit too heavy/powerful and will do a 75-78% throttle scale, as you did. But with 78% throttle on the 1804, wouldn't the EX1404 2750kv motors be a better replacement choice than 3500kv? Either way, the 1404's seem to be the better size for this type of build. Can't wait to do some flight tests but cold weather has been an issue.
I tried my 1404 3500Kv this afternoon on the Atlas and they work at 100% without limiting the power (around 34A) which is beneficial since I save 20 grams and the inertia is lower on all axes. The 1804s are more torquey but heavier and having to clamp them is not good for performance. My friend uses the same 1404 3500Kv on his Chimera 4 and it's very good with li-ion for slow freestyle, crusing and mid-range. The 1804s are very good for freestyle, on a 3.5" or 4". For Kv I think that 3500 is very good because less KV leads to softer reactions and more prop-wash.
Right now I have jello on my O3 since it crashed and it's a problem I can't seem to resolve. When everything works this drone is great, but you know, FPV is not a smooth path!
Hi, for the GPS installation you can check out my Roma L3, if you are interested I can share the STL so you can print the same. https://rotorbuilds.com/build/33740
nice photos. how is the flight performance?
