Hi,

I have flown my Galactika now with factory default setting. Only 5 flights on Saturday in not so good weather with low cloud ceiling and rainclouds around the field but it was no rain coming down where I was, and also rather cold, light to moderate winds.

I need to do some changes, but I'm little unsure how I should consider the T-canaliser incidence.

Factory setup is supposed to be:

Engine: -1.5 degrees down, 2.5 degrees right
Elevator (stab): 0 degrees
T-canard: -0.3 to -0.8 degrees
Wing: +0.6 degrees

I have this (not changed any factory setting yet as I wanted to see how it flew with it):

Engine: -1.5 degrees down (2.5 degrees right maybe - I have not measured yet)
Both nosering and motor shaft is at -1,5 degrees down.

Elevator (stab): both at 0,1 degrees

T-canard: - 1,4 degrees

Wing: both at +0.1 degrees

I have measured with Wixey WR300 Type 1 and Robart metal bar+V-clamps.
I have measured everyting several times with same results. Also measured serveral times with a second Wixey WR300 Type 1 and got same results.

I have CG at Oxai recommended 212 millimeter (8.346 inches) from wing leading edge where wing root and fuselage meet - it is exactly on center of wing carbon tube.

I have some right trim and some up trim to get the plane to fly level right now.

I will try to increase wing incidence to + 0.6 degrees and set stab incidence to 0 degrees to start with.

What bothers me is that T-canalizer will still be at (minus) -1.4 degrees if I do above. Factory recommend it to be between -0,3 to -0.8 degrees.
It is at least - 0.6 degrees to much if I leave the T-canalizer as it is.
The T-canalizer on Oxai Galactika is huge so it has probably rather big impact flight characteristics so to be as much as (minus) -0,6 degrees from factory max limit might be just to much?

What would You do in this situation?
