So I have a flight thats averaging 1min 10 seconds - 20 seconds ish but there's a slight problem with it now. After regluing the tailboom section due to damage, the flight's behaviour has changed in that it starts yawwing right. This happens only when the flight is losing power and starting to descend but yaws left in a circle as normal during takeoff and higher speeds. Would anyone know how I may fix this issue?

thanks in advance.

Oh and I forgot to mention, I'm using the division B freedom flight kit (2024 season).

Check your stab tilt for turn under power. If looking from the rear of your plane, the left side of the horizontal stabilizer should be higher than the right side. If it starts to turn right on decent, Check that your tail boom is straight and that your wings have no warps or twist in them. Good luck with the retrim process.

If late in flight, it is likely stab tilt is the wrong way, or you have a warp in your stab. Be sure the stab is perfectly flat (Leading edge and trailing edge parallel) and that the left tip is higher than the right tip as viewed from behind.

Boom offset is a possibility, it should be offset to the left (giving left rudder). Boom offset will affect the whole flight,. tail tilt affects late flight more strongly.

Check out the basic trimming document on Freeflight.org science Olympiad page of resources.
