Balancing procedures for control surfaces for an RV8
See above. I'll only add this...the conservative approach is to remove the bolt tying the elevator horns to the elevator pushrod, and balance the left and right surfaces separately, after painting of course. The left side may need a bit of additional weight becasue of the trim servo.

AOA v IAS …PhatRV
I had a chance look at the BLACK_BOX data from my latest flight. I plotted the IAS to the AOA % at the landing phase. IAS is in the x-axis. AOA % is in the Y axis. During the final approach, I would try to keep my speed above 65 knots, closer to 65 when I am solo or closer to 70 when I have a passenger. Over the fence, or about 50ft AGL, I would be less than 65 kts.
The AOA data was from the calibration where the stall speed was deliberated set at 60 kts with zero flap.
I notice the small band of AOA% around these two IAS values. I also mentioned in the previous post that the beeps were not consistent. This plot shows the vertical spread of the AOA at around at any IAS you pick.

Flap Help
Something certainly is wrong with my assembly. I disassembled the push rod to double check my measurements. The first photo shows the distance from the flap crank to the center of the pivot bolt in the flaperon mixer where the push rod is attached. The photo is distorted, but the crank is positioned so that the push rod is perpendicular to it as described in figure 4 on page 32-07. The 12" mark is aligned with the edge of the crank, and the distance is actually a little shy of the 11-29/32" called for. (I believe the discrepancy is due to the distortion of the image. It checked out on the bench before I installed it.) A longer push rod isn't going to help, though.
