I think we can assume that it takes just as long to charge all the smaller batteries as the one big battery. If parallel charging was alowed it would be cheating for option A 😆

What determines if a shop's stock is on the site? Droneshop.nl is one of the listed shops however what they have in stock is not added to the site.

Interesting project! I've flown some old brushed whoops. What I can say is that they wear out a lot faster than brushless motors, expect to replace them every 5 hours of usage. Also make shure you get the right size props since the 615 brushed motors often use 0.8mm shafts which will only fit with 0.8mm props (1mm will be too loose).

A little outdated but they are alright. About the same feature set as the BetaFPV VR04. 

Haha wow! I haven't seen a Y-frame since 2017. Cool project!

I don't really think there's a right or wrong placement for the reciever module, as long as it doesn't short out anything. You also wouldn't need it at an accessible place because it's mostly a "set it and forget it" component. 

What I've seen many people do is mount the antennas parallel to the motor arms (so you could put them on the two front for example). However since you've bought (in my opinion a way overkill) dual band reciever with diversity, you would like to have both antennas in a perpendicular orientation to maximise the efficiency of the diversity module (for example one lying flat and one pointing up). 

A monitor is indeed the way to go if you want to keep using FPV feed without goggles. HDZero has their own monitor, and the DJI goggles have a mini hdmi video out that can be hooked up to an external monitor with. For walksnail it's a special case though. There's one specific monitor which is perfect for the walksnail system, since it's compatible with the 100fps format. JB has a video covering it:

@Fuocothedog I would like to correct myself. These goggles aren't the greatest option out there, but they are certainly workable. The goggles require some modifications which will probably land you above 100 euros eventually:

- A module bay and VRX module can be added to improve the bad built in video reciever (without modding the goggles itself)

It's the name for a region around Vancouver in Canada

@Forol1561  First of all, I don't think putting your camera angle at any degree is considered cheating. Secondly, in real life settings I don't see many people go above 50° or even 45°. And lastly, I've also adjusted my camera angle to extreme limits in the sim before to get the best times 😜

Wow this is really good for 1.5 hours! Did you have any practice prior to Liftoff: Micro Drones?

Wow, a real blast from the past! A friend of mine has a bunch of drones laying around from 2016 - 2019 (his parents stopped with the hobby when the new regulations came). He also has a teleporter, with a module bay modificitation though. He also has a Spektrum DX6i and some quads from the same era, some of which have F3 processors (which betaflight abbandoned right after they stopped flying). I might make a post about it some day.

No, these are not worth your money. The FOV on the screens is very narrow and do not look very good. Also: no DVR without a mod, which also is a downside. If you want an educated opinion, Joshua Bardwell did a review on them a while back:

By the way, I didn't know you were the founder of SpeedyPizzaDrones! I just saw it on your profile. I think people will be excited for a product like this (Build your own prop...)

I'm interested in your long posts mate! I don't speak Italian, but google translate comes to the resque! Looks like you've been putting solid work into this project, hopefully you can get some recognition so people can test it out and catch the attention of manufacturers who then can specify their metrics. I think researching materials could be a next step in this project, because that also has an influence on not only weight and durability but also flight characteristics. Keep up the good work!
