Incidence experts needed!
 
Maybe I should never have looked, but I put an incidence meter on my plane and WOW! What a suprise.
I bought a WH 28% Edge V1.1 last year and am just now getting around to starting...er, finishing it. This is my first big gasser, so I wanted to do it right. The dowels on the left wing didn't line up with the holes on the fuse, so I put a meter on it to make sure I didn't change any angles while adjusting the holes.
I needed something to calibrate from so I started with the right side stab and set the meter at zero. Here's what I found:

Right stab root 0" (calibrated from here)
Right stab tip 0"

Right wing root -2"
Right wing tip -1.25" (positive washout?)

Left stab root -2"
Left stab tip -2"

Left wing root (this is my problem child, but I don't know where to set it)
Left wing stab

If anyone has any guidance, I'd greatly appreciate it.

or...

Right stab root +2"
Right stab tip +2"

Right wing root 0"
Right wing tip +.75"

Left stab root 0"
Left stab tip 0"

Food for thought.

First, use the top edge of the fuse where the canopy frame mounts as the baseline.

Adjust the other parts to be 0 relative to the baseline. Do this by enlarging the aliognment dowel hole and rotate the surface until correct, then;

on the wings, glue a new donut over the dowel to secure the location.
on the stabs, fill the void with epoxy.

Anything within 1/2 degree is within tolerance.

I would not worry about the wash-in until you fly it, that could be caused by the aileron being slightly off center and be an actual twist.

You're right. A negative on the scale would be a positive angle of incidence. Either way, should it be that far off on a WH product?

Thanks Tom! As always, fantastic support from WH :D

I'll jump out of this thread and back into the build thread with pics and progress.

The planes from Thailand occasionally were a little off, one other reason why production moved to China.

I guess most average flyers like myself don't usually check and just trim it out in flight. Thanks again for the info[sm=teeth_smile.gif]
