The article states "Most helicopters have a single main rotor, but torque created by its aerodynamic drag must be countered by an opposed torque."
This is factually incorrect. The torque is not created by aerodynamic drag, it's the result of an equal and opposite reaction force (Newton's Second Law). It happens in a vacuum. Spacecraft have reaction wheels for attitude control that work on this principle. — Preceding unsigned comment added by 146.90.76.143 ( talk) 17:29, 8 July 2023 (UTC)
I'm reading through old Time Magazine issues. The March 1923 issue discusses Thomas Edison sending Dr. Boothezaat a congratulations for a test of a helicopter by remaining in the air for 2 min 45 sec at a height of 15 feet. Also see https://time.com/vault/issue/1923-03-03/page/23/. — Preceding unsigned comment added by Noloader ( talk • contribs)
This paragraph needs updating to reflect the fact that the NASA Mars helicopter (Ingenuity) has successfully flown many missions on Mars. Pawprintoz ( talk) 00:57, 9 January 2023 (UTC)
The source is not available online and is in French.
And so I got curious: what are the reasons why the word isn't analysed helic- and -pter?
I'm assuming the source goes into some detail. Or, if you have another source discussing heli- and -copter?

Our sentence is:
which makes the following explicit and implicit claims:
Now then, does anyone have access to our source (Cottez 1980) that can contribute? Our only other source, Free Dictionary, is of questionable quality and does not go into sufficient detail. Otherwise the entire sentence becomes dodgy. We should not make the third claim without going into any details of what those reasons are, it makes the entire sentence very vague.

The following phrase, whilst partially correct, is misleading:
"
Most helicopters have a single main rotor, but torque created by its aerodynamic drag must be countered by an opposed torque"
[Suggested Correction]: Aerodynamic drag affects the entire aircraft. Specifically, the aerodynamic drag experienced by the rotor blades is transmitted to the airframe by an equal and opposite 'reaction torque' via the rotor drive shaft and hence the engine mounts. Unlike an automobile engine, in which the. car body cannot rotate in response to this torque, a helicopter is free to rotate around the rotor drive shaft axis. A tail rotor, 'anti-torque rotor', is therefore necessary to establish a balancing (anti-)torque to prevent the airframe from spinning around the rotor axis.
Suggest the text is amended accordingly. 86.26.142.91 ( talk) 10:49, 12 June 2024 (UTC)
