Being that it was windy you will no doubt be using different amounts of rudder for each direction. It's best to test using the same amount of rudder when testing knife edge. I honestly have never had an airplane that would tuck one direction and pitch in the other. All my airplanes are set up so that at 1/2 throttle it takes full rudder to maintain level knife edge. That makes testing and adjustments easier. I doubt you would be able to use the same method for the Intruder however. We have spoke about getting your CG correct. Do you in fact have it locked down to the point of not changing it again? We spoke about the 45 degree inverted upline test and how your intruder wanted to drop the nose fairly quickly. Have you corrected this yet. IMO until the CG is correct there really is no sense in trying to trim anything farther as CG affects everything else. Case in point. I picked up a 2 meter ship a few weeks ago that had been set up for YS 160 power. Don't get me wrong, I love YS engines but truth is I will be more competitive with E power so the entire fuse was gutted. I pulled out 3 lbs of " junk " the airplane didn't need and did my conversion with the appropriate strength of components. The airplane was test flown on Friday. During the first flight I did the 45 degree inverted CG test. It was holding track hands off. Ok let's try a knife edge both directions. Sure enough both directions tuck to the gear. I took the RX battery and moved it from the wing tube to as far forward as I could get it. Back up in the air, re trim the elevator for the now slightly forward CG as compared to earlier. Now the nose drops ever so slightly on the 45 degree test and knife edge is locked on but with just a touch of proverse roll. I also found that it needs a touch more right thrust which will be done before and more trimming adjustments are made.

point being is that trimming must be done in a sequence of events starting with CG first, then thrust adjustments, then incidence changes and lastly maybe 20-30 flights into trimming you may be fine tuning the final 5% with some mixing. You may also get some good info by posting this in the classic pattern forum. Keep in mind as well that you will only get so far with an Intruder.
