RE: Convert Millimeters to Degrees
 

I think the original question was dealing with converting suggested throws stated in one form to a form you can measure with the equipment you have. It was a pretty straight forward question, and as usual it was answered well in the first couple of posts.
Sheesh!

RE: Convert Millimeters to Degrees
 

Who, in these times, does'nt have a mm measuring device? Last time I looked, both metric and standard are on any ruler. So why convert to degrees? Just set a ruller down on the surface your airplane is on. Take a note of where nutral is, move your control surface up or down, adjust to the said amount of throw. How complicated is that? LOL

Why make it more complicated than what it is? Unless, your an engineer and cant understand simple terms hehe.

It probably should be noted that 0.5mm in 10mm is 5%

0.5mm is difficult to pick up with a ruler graduated in mm (our TE's aren't too sharp, surfaces aren't deep and the throws are small) so the worst case scenario of having one elevator traveling up 10.5mm and the other traveling up 9.5mm (a 10% difference in travel) is possible.

Converting the mm value to degrees allows me to use an expanded protractor scale arrangement where one or two clicks of subtrim are actually noticable. If I were setting the throws on an aileron that's 4 or 5 inches deep with ~45deg travel eack way, then being a millimeter or two out at the end of the travels isn't a big deal..

Getting the mechanical setup right is the best place to start before you start messing around with endpoints and whatnot...

Jarvis asked how to convert mm to deg, he got several answers on that, I did not see anywere the question of what he should do or what is best, it does not matter what does he wants to do next, it was one question and some of you are telling him what to do now because of what your personal thoghts are?????

Stick to the question or don't say a word,unless there are more questions derivated from the original, it's better for the forum.

Spoken like a true wanna be moderator. No where did I see anything that said this is apereia's forum.

Ths is an open forum, an exchange of ideas. We presented our own ideas on how to do the same thing without making it complicated. The answer to his question could have easily been googled to get an answer. He chose to bring it up among fellow modelers and we all gave our ...constructive...opinions.

Go back to bed and leave the discouraging remarks alone.

What correction factor should he put in the formula for altitude?

I'm sure a plane in Colorado needs more throw than one in Palm Beach.

Wbg,

So much for someone sendeing somebody back to bed.......BTW I will never tell you where to go or what to do, it will be bold on my part and ridiculous.

I did not referred to anyone in specific, but if you take it personal it must be for something...........

I see you do noy use your name, I do, please make an effort and write it right if you are to refer to me again......

No matter your responsonse I will not contribute to keep filling this thread with unrelated commentaries to the subject.

Thanks

To measure within 0.01 degree resolution, you can use MU9000X [link=http://www.aeroperfect.com/mu-9000x_usb.html]MU-9000X[/link]. Some of the pattern pilots loves it.

Just convert mm to inch and use a ruler, that mountain keeps getting Bigger.
