Just remember, the gyro alone is not accurate as it drifts allot over time. You need a stable plane or a way to compensate for the gyro drift.

ok i'll keep that in my mind thanx for every thing , and wigh u the best of luck, c u

 

hey guys, i wanna ask u somehing that i heared early this evening.
it's about using the compass as a yaw rate sensor!!!
so is there anyone knows about this thing???
thanx in advance

 

A compass (magnetometer) will not work while the plane is tilted. You do get tilt compensating units, but even these don't work 100% on the airplanes.

btw: The compass will only give heading, you need to take 2 heading readings at a certain interval... do some maths and it will give you yaw rate.

hello everyone, can u plz look at the pic attatched and tell me if what i stated is right or wrong ??
if it's right:
let's suppose that we have a 10 cm fuselage ok, and that the airplane is flying with an attitude of let's say 2m and we send a pitch down command for the airplane, and we want it to produce 30 degree angle of pitch , so depending on the rule whitch says that if we want 30 degree angle of a triangle then the fronting line of the wanted angle must be equal to the half of the rad line so using that would produce the following:
as the rad is equal to the half of the fuselage length then rad =5cm, ok!
and the half of the rad will be equal to 2.5cm right?
so the fronting line must be 2.5cm to get 30 degree pitch angle
and as i supposed above that the attitude is 2m=200cm
then to provide the wanted angle, that attitue must be decreamented by 2.5cm...
so is that right or i'm in the wrong way???
thanx in advance
