What is happening to questions asked?
Have asked what incidence means or how you check it several times it seems and my posts are not there if this is the wrong forum for the question then where would i ask this? I have seen pics and stuff of people checking with incidence meters and just would like to know if i need or have the ability to do it. But don't know what they are checking for. And how do you know what it should be if it is wrong. Please someone help me out here I am not a complete begginer but still have questions on some things that i don't know about. Thanks in advance to all the inteligent folks that can help me out here.

Just click on your user name and it will bring up your profile, at the lower left you see your last 10 posts, or you can search for your last 50 or whatever.
Thats the thread you started, complete with answers.

To find the Kit Builder's Forum, select "Forums" at the upper left side of the screen, and scroll through the airplane forums.
To set your preferences, so that only forums you want to read show up when you click on "My Forums", look at the upper right side of your screen and click on the "Settings" menu bar item. You will have to go through the same selection process.
Good luck,

RE: What is happening to questions asked?
Incidence is the angle at which a wing or stab (Or any plane surface) moves through the air.
It would be best described as an imaginary line from where a wing splits the air molecules to where they reunite.
It can be measured with an incidence meter

Incidence is the angle at which a wing or stab (Or any plane surface) moves through the air.

It can be measured with an incidence meter
"The angle at which the wing or horizontal tail of an airplane is installed on the fuselage, measured relative to the axis of the fuselage."
Example: The horizontal stabilizer is set at 1° positive incidence relative the longitudinal axis. The wing chordline is set 3° positive to that LA. The thrust line is 2° negative to the LA. Aerodynamically that airplane has 2° positive incidence at the wing and 3° "downthrust" with 0° stab. The horiz. stabilizer determines the true aerodynamic incidences as it is always zero.
>>>"Incidence is the angle at which a wing or stab (Or any plane surface) moves through the air."<<< Nay! Not so!
That is angle of attack(AOA). AOA is determined by the applied load factor from another source. For example, the wing in maneuvering flight is being forced into various AOAs from the applied force of the stabilizer-elevator combination as forced by the pilot, or servo, or whatever unit changes the elevator or slab.
The required AOA of a wing is determined by what it is being called to do. If you wish to fly straight and level, then the AOA, or also known as Coefficient of Lift (Cl) has to satisfy the required lift being called for: Lift = Cl x 1/2 (air mass density x velocity squared x wing area) Therefore the AOA given a constant airspeed, constant altitude, is forever changing as fuel weight is expended.
Angle of Attack and Angle of Incidence are two terms, totally different, but often confused by aeromodelers and sometimes even pilots.

RE: What is happening to questions asked?
i just use it to make sure the left and right side of the plane are moving to the same angle on hte surfaces and to check throws. but hey you learn someithng new every day

RE: What is happening to questions asked?
Sorry for the same question fella's.
Man that is some kinda stuff there. I kinda understand a little of what your saying. But that is alot to comprehend at one reading lol. Thanks Hoss and the rest of you also. I like the measuring to see if both sides are at the right angle of the fuse. Am I correct on that assumption. Or is it that when you eyball the stab level to the wing level it is the same? Or a combination of both? OR even dumber ? what determins the axis of the plane? Thanks again

Unfortunately, he was so busy trying to be impressive that he gave an answer that totally confused a "beginner". They call the Forum "BEGINNER" for a reason Horace! K.I.S.S.
