RE: super decathlon fin
hi
i flew plane today.
CG was on at manual recs,
however, during flight, it looked tail heavy
i tried to adjust with elevator trim,
this improved somewhat.
i was able to fly around a bit
but it did not fly right
kept trying to roll to left also
so i landed it
something is wrong.
one time, i saw my friend's home built coroplast plane fly, and it was doing similar thing.
he then adjusted both ailerons to be down some, i think, if i remember correctly.
