Hi Vince,

Nice to hear that we are close on trimming.

-About the canalizer, what I did on mine was to glue the rear fuse canopy metallic pins (they are screwed to the fuselage and tends to screw off with flights), I use a screw on the front part because I only have a 2mm gap with the Hacker Q80 14xs (I did a lot of snaps and it is rock solid).

-About rolling tendency:

At the beginning I was carrying about 5 clicks of left aileron trim, The knife edge was close to perfect on one side and with 2% mix to the other.
I decided to check the incidences and I found a small misalignment on wings and stabs. I could solve the wing difference sanding a little bit the wing pins and the fuse holes. I decided not to touch the stab incidence because it was a very small difference and it is so difficult.

Now I have 0 trim on my ailerons, but still have the rolling tendency.

But..., If you try a knife edge loop with full rudder you will see that the mix decreses a lot at the 30% of the travel, you only need it for the very first part of the rudder travel and then remains flat (it isn't linear mix). As I said on the last post I need to check it again, because now, I have my engine thrust close to perfect and improved the flight performance a lot. I think this is a normal mix on most F3A planes ( but as you, I don't understand why one side is perfect and the other no) If you can solve it please let me Know.

I post some pictures of my plane, you will see where I have my battery pack now ( 980 gr.)
