There’s a few collective pitch quadrotors that use a single gas drivetrain to spin the props and servos for pitch control. Example: Stingray 500 - https://yout

Agree with your observations. This is a big quad, 30” (fixed pitch) props and not a ton of payload...probably serial.
- pfundstein 6y agoWhat advantage would a collective pitch quad have over a helicopter?
- jcims 6y agoDunno. I imagine it's use-case dependent, quads can go faster (rc quads can hit 200mph) and are more nimble (presumably due to lower moment of inertia). I have zero clue how they would scale up though. All I know is that I'm not flying in a quad and helicopters seem to haul heavy shit pretty well.
- pfundstein 6y agoIt sounds like you have seen little of the speed and agility RC helicos can exhibit, for example: https://www.youtube.com/watch?v=PptMrBFAO-A https://www.youtube.com/watch?v=PptMrBFAO-A
