[edit] Mnemonics in Forward flight section
I'm not sure this adds to the article's ability to explain how the controls work. If it was in a descriptive, encyclopedic tone, it might be used to explain the relationship of the flight controls and interactions required between different control inputs. But, as it is in the article currently, it just seems a bit of information that will only benefit student helicopter pilots, or those learning to fly R/C helicopters rather than an everyday reader. --Born2flie 17:52, 25 April 2007 (UTC)
- The following discussion is an archived discussion of the proposal. Please do not modify it. Subsequent comments should be made in a new section on the talk page. No further edits should be made to this section.
The result of the proposal was the articles were merged --Born2flie (talk) 22:58, 28 November 2007 (UTC)
[edit] Recommended merge
Cyclic pitch & Collective pitch → Helicopter flight controls — The first two articles are close to duplicating information within this article, and by merging the two to this article, the relationship of the controls to the rotor system can be better explained to readers.

[edit] Survey
- Add * '''Support''' or * '''Oppose''' on a new line in the appropriate section followed by a brief explanation, then sign your opinion using ~~~~. Please remember that this is not a vote; comments must include reasons to carry weight.
Support I think the two stubs would help to better develop this article.See the recommendation above for my comments. --Born2flie 13:26, 1 May 2007 (UTC)
- Support: Article should be merged, as separate pages are quite sparse. (Above comment is ambiguous.) Redirects can be used on cyclic pitch and collective pitch. —The preceding unsigned comment was added by Algocu (talk • contribs) 11:35, 12 May 2007 (UTC)
- Support: The articles should be merged. This would flesh out the fight controls article a bit. --Knag 19:03, 5 July 2007 (UTC)
Oppose Ok im not an expert but i know that collective pitch and cycle pitch are diffrent. collective pitch changes the indevidual blade angle to change lift cycle pitch changes the angle of the blade head to move the helecopter in the desired direction. im ok with the stubs being merged into the artical but they need to be keep in seperate(SP) "chapters"

[edit] Fourth control, interaction of controls... Offer to help
I have no idea how to edit on Wikipedia - I would be willing to review and even generate text (my training is in aerospace engineering) - Traditionally, the engine throttle, the fourth control, is a twist handle on the end of the collective. The amount of power needed to keep the blades spinning is a function of: the lift being requested, the RPM of the Rotor, flight speed and the amount of "lift" required by the anti-torque tail rotor. Like any wing, the amount of drag on the "wings" (the rotor blades) is the result of viscous, form and induced drag. The total drag for a wing typically has a minimum at a certain flight speed with induced drag predominating at lower flight speed and viscous and form drag at higher speeds. Similarly, the rotor blades which are merely rotating wings (albeit in a very complex system) will have a minimum drag at a certain rotor RPM. However, since the helicopter has the possibility of forward flight, the drag minimum can vary with flight speed (see advancing and retreating blade). Further, when considered as a lifting "thrust actuator disk", the rotor generally has induced drag so that the whole helicopter system will have a flight speed where there is minimum drag and thus minimum power needed. Etc. need to discuss torque vs power, interaction of controls (increasing lift - up collective) increases drag ---> torque --> need for increased tail rotor lift), loss of lift of retreating blades setting maximum flight speed, etc. DSMOSELEY@AOL.COM 03:45, 4 August 2007 (UTC)Thomas S.
