I have finished rebuilding a plane I crunched on its maiden flight...it
was a Tower Hobbies Apprentice, advertised as a first low-wing plane (I
built it as my second plane). Although I crunched it due to my error, I
was fighting a persistent left roll tendency. To fly straight, it
required constant and significant right aileron (I crunched it while
trying to trim it out).
I checked everything before the maiden flight and re-checked the wing and
tail after the crash (they were essentially undamaged except for small
wing tip ding) and the ailerons were/are straight and even, the wing not
twisted, lateral balance OK. Trim levers on the radio and control
surfaces were centered. So, I'm trying to figure out why it rolled left
so hard before I send it up again with it's rebuilt nose.
One thing I noticed is the plans call for 6 degrees downthrust and no
right thrust. Seems to be the plane should have some right
thrust...anyone else have this plane who can comment? Any ideas on what
to look for on a plane with a left roll tendency?
Thanks in advance for any ideas...
