hello. this was this birds 3rd flight, and by far, the best yet. but to me, still not good.
1st flight: plane took off no problem, i immediately noticed it wanted to keep climbing, at the time, i was unaware, but the bird was flying way tail heavy. the way i checked CG , by suspending plane from wing tips at CG point, was way misleading. I then trimmed elevators, to help with flight, but this was not much. when i could get plane to fly level, by holding elevator stick up, then once plane in semi level flight, it would immediately roll to left. soon after that, very quickly, i said, this is not fun, this is not the way to fly. believe it or not, i was able to land the plane, only damage was the landing gear bent on one side. this was fixed easily.
2nd flight: i addressed CG issue, i added about 16 ounces of weight to nose, and i shifted all servos and batteries as far forward as i could. this time, plane took off, did not appear to be tail heavy, this was improved flight pattern from before, however, plane kept wanting to roll left. i also had made a change to the plane prior to second flight, whereby, i made trailing side of right wing sit 5 mm higher on right side of wing bay saddle area, using incidence meter, now both wing roots were even. i still was not satisfied with this flight pattern.
3rd flight: i redid the fin, so that LE was not to left of TE. i believe the fin is well centered this time. this flight was best of all, however, plane did want to roll left. trim did not help much. prior to this flight, i did a CG check, and plane was neutral, i also checked side to side balance. i placed a string under a low hinge on rudder, and tied another string on prop hub, my wife and i then elevated plane off table in a room with no wind or breeze. i was thinking that possibly left wing would be heavier, but to my surprise, it was the right wing which was heavier??? i then added 1.5 ounces of weight to left wing tip. this leveled it out side to side. the flight, again, plane kept wanted to roll left. i am still not satisfied with this bird. i am now going to put all batteries under gas tank, and remove added weight, hoping to balance it this way. i may be able to get rid of 12 ounces of extra weight. that will make plane 18 .5 pounds, better than almost 20 pounds it was at first.

i need to make a correction. the Dynaflite super decathlon build is for 2 degrees right engine thrust and 5 degrees downthrust.
the incidence is -3.5 from stab and -2 from wing.

i believe my plane has +3 degrees incidence wing relative to stab.

the thrust is: +3 degrees to right., downthrust is +2.5 degrees

thank you for the advice and guidance.

do you think i should add more thrust to right and down?
