I do agree that trains and then streetcars created suburban corridors, but suburbia as we know it today became possible with highways and mainstream car adoption post WW2, at least in the US.

Ultimately the early generations of flying cars are not capable enough to replace all car use. The Tesla Roadster or even the Nissan Leaf did not replace a first or second car but was an additional vehicle for most buyers.

Walking made 2-mile villages feel local.

Cars made 20-mile cities feel local.

Flying cars will make 200-mile regions feel local.

Yeah it's a strange term because it probably originated relative to fixed wing planes. Ie a VTOL plane. But now multicopters are the predominant species so VTOL can sound redundant to most drone builders today.

Thanks, really appreciate that

Thanks! Not robust exactly because the filament I used is has really poor impact and UV resistance. But that's the tradeoff with lightweighting

Yes, you're right, I meant ACCST not SBUS

This is neat! It seems like it could help with set up speed generally and also simplicity for beginners

Aesthetics follows function in this case. And agreed VTOL is not beneficial at hobbyist scale for most because of the ease and short distances required to hand/runway launch and land an RC plane

Great question, but spinning lifting motors in cruise draws more power than it's worth for efficiency.

There's ways to use differential thrust for multiple cruise motors to roll if not positioned at spanwise Cg (e.g. wing mounted like in a commercial jet), but again, usually not efficient. Servos are a small mass fraction relative to other components.

I actually managed to batch print the wing sections which you can see in the video in the rebuild chapter. That works really well for wing sections because each takes up a minimal bed area
