Been flying my Arrow tiger now for nearly a year. Found after about 6 months or so that up elavator was sometimes not as affective as down elavator.
Found that the control rod was bending a little whcih ment it was not giving the full throw. I strengthened it at servo end with glue and it helped.
All in all, pretty happy with the way it flys.
BaldEagle, How did you introduce 3 deg of down thrust. Here are some pics of it when new.
