I'm getting the expected roll response but getting some strange elevator behaviour during test flights. Sometimes the plane will go into a slow dive and sometimes it will fix at an AGL around 50 meters no matter what altitude I enter in the configuration tool.
This may be due to not understanding how the tool should be used.
1)What is Alt(ref)?
2)How does the elevator trim in the Configuration tool options affect flight? What does the trim option do that is not done by tweaking the #Define values in the program?
