Clean up

How about moving all this safety stuff to a Wikibooks article, in a similar way done on Radio controlled airplane/Wikibooks:RC Airplane? --phatmonkey 12:58, 21 December 2005 (UTC)

That sounds smart. Um. Is there a description somewhere of the difference between Misplaced Pages and Wikibooks? I can partially understand the difference, but I've been unable to find any comparisons... like which is better for what sort of content? Zebruh 18:00, 21 December 2005 (UTC)

Misplaced Pages is for describing what a radio controlled helicopter is, Wikibooks can be used for describing how to use a heli, amongst other things. --Phatmonkey 19:59, 21 December 2005 (UTC)

hey. thanks.Zebruh 23:25, 21 December 2005 (UTC)

Alright, this was getting a bit old. I've removed all the safety stuff, it's in the history if anyone wants it. --Phatmonkey 23:03, 27 December 2005 (UTC)

Bell-Hiller mixing and other technology unique to RC

Is it worth mentioning the hybrid Bell-Hiller mixing system? As far as I know, this is unique to RC helis and might be worth mentioning. There are also a few other things that are more common in RC helis than in fullsize helis that many people don't know much about, such as heading hold gyros, and flight performace characteristics such as sustained inverted flight etc. --Soupisgoodfood 13:05, 13 July 2006 (UTC)

Indeed, i'd be interested to know the details of how RC helicopters are able to fly inverted. --born against 14:10, 25 January 2007 (UTC)

I think Bell-Hiller is a head design. The mixing system is still (e)CCPM. Full sized commercial helicopters can't fly inverted because their collective pitch is limited. 3D RC helicopters control their vertical speed via collective pitch not by how fast the motor is running. The motor is kept running at the same power, pitch is increased to ascend, decrease to decend. If the pitch is negative, it's actually being pushed down. If you flip the helicopter at this point, it'll fly inverted. --NYC 19:31, 13 April 2007 (UTC)

I added a section mentioning Hiller and Bell-Hiller style rotor heads, after I was frustrated to find that this information didn't exist on Misplaced Pages. However, I think it might be a little too much to describe the specific functioning of these systems (the flybar, mixer arms, etc.) so if anyone knows a good external link describing these things, that might be a good addition. --Squeakywaffle 22:19, 16 September 2007 (UTC)

Photos

I think we need to replace the photo of the MS Hornet. It's not the best photo, and we already have an electric heli. I'd like to see a photo of a Raptor 90 hovering inverted. I'll post a topic on RunRyder.com asking for a free image to use and see what turns up. --Soupisgoodfood 13:08, 13 July 2006 (UTC)

F3C

I'd like to make an F3C page, linked to from here. We already have the 3D Masters and the FAI. It would be nice to describe it, compare it to 3D and list the previous locations and winners. If you have an opinion please respond, otherwise I'll do it in a few days. --AndrewDonaldson 09:49, 4 October 2006 (UTC)

Radio gear

Prices (not just for radios) should be removed or atleast dated. Prices change constantly. I known a simple basic 4 channel radio can be had for less then $40. This is only for the transmitter since in RC community, radio refers to the transmitter. There is really no upper limit on the cost of a complete radio system including, tx, rx, gyro, servos etc. Also on the PCM resolutions, it lists (512 values 10 bits) (1024 value, 11 bits) etc. Mathmatically it doesn't sound right, 512 values is 9 bits, 1024 values is 10 bits. I don't know if start/stop/parity etc bit is used but it's wrong to imply 10 bits have 512 values. --NYC 19:47, 13 April (UTC)

Electric helicopter

The following was part of a stub article titled "Electric helicopter" which pretty much refers to electrically powered R/C helicopters and a model or two of UAVs:

Advantages of this type of are:

• Improved maneuverability due to the greater availability of torque of the electric motor.
• Improved safety due to lower risk of mechanical failure.
• Less risk of explosion or fire in the event of a collision.
• Somewhat quieter: no exhaust noise, but the rotor will make the same noise.

Their disadvantages are:

• Shorter flight range and air time

These advantages/disadvantages are unsourced and I don't have the time to verify them. Basically, everything else from that article other than what I left in the Commercial applications section is already covered in this article. --Born2flie 16:20, 14 September 2007 (UTC)

The disatvantage in a few years may prove to be an atvantage, speaking as in advancing technology in batteries.
