Let me know if you want me to calculate your decalage from photos. Decalage will definitely impact how your airplane will fly at different CG loadings. If you want me to do that, please contact me offline and I can get you set up for that. I have done the same thing for a number of people on this list. If you need a refresher on decalage and/or Q200 aerodynamics. You can look at the following:
Q200-Tri-Q200 Aerodynamic Study
From: main@Q-List.groups.io <main@Q-List.groups.io> On Behalf Of Bruce Crain
One of our TriQ 200s had a 9 lb weight way back in the tail. When flown with two people it had and almost uncontrollable PIO! The 9 lb weight was removed and the battery was moved forward to just behind the seat back. It flew just fine after that. Be sure you do calcs for full fuel loaded passengers and luggage to see if you are out of the envelope aft.
I moved the battery forward in my TriQ200 to the right just beside the passengers calf on the canard and have flown it for years.
Just saying do all the possible loaded configurations not just an empty calc.
Can anything be relocated aft of present position? Every pound moved aft no matter where on the airframe makes a difference. Give everything a critical why does it have to be located there.
Just a thought before adding dead weight. With my Corvair/Dragonfly I had to locate the battery aft of the wing. It still was not enough so I went to a heavier battery. Odyssey 925 solved wt and bal plus carries more amp hrs. Duel function and it is not a Bob weight on a long arm that suffers inertial effects.
