a wing has to produce lift ,,so I add positive inc. in the wing ,,not the fuse ,,like your set up requires.The airplane don`t know up,down sidways ECT we do ,
.
I challange you to try it 1/2 deg pos. to the centerline of the fuse start there,,and play around with it.
well -Iwon't even suggest you change your methods of trimming -it works for you
here is a point to consider tho:
by changing the angle of the wing - you do not change the lift the wing produces -as you noted . It simply changes relative angles to stab and fuselage
the wing will assume the correct angle for lift required -all on it's own.
Ask George Hicks -
I know you don't believe me.
Example:
IF a model weighs 11 lbs -the wing must assume an angle which produces 11 lbs lift -for level unaccelerated flight at a given speed..
IF you shim the wing up 1/2 degree- it STILL flies at that angle.
However all the rest of the airframe now is at 1/2 degree LESS angle to direction of flight. (this is why you reduce your downthrust )
The horizontal stab (elevator) must reduce effective angle to maintain the necessary downforce for the new wing position.
Changing the CG changes ALL of this.
Except
the wing always flies at the same angle if the speed and weight (effective weight ) is a constant.
