Thanks for the feedback -

I will check the weight and balance again, but have been flying with an
instructor the entire time and he claims that most of the Nexstars he
has been flying exhibit some of these characteristics. Wouldn't the
need for the large amount of down trim indicate that the model is nose
heavy?



I know where you are going with this trim versus CG thing. I also think that
you know that there is no way to really trim tail heaviness, but it appears
to help a bit at first.

I don't know your instructor, but I have to wonder about his experience
level. This is not to say that his experience is deficient. As I said, I do
not know him/her.

However, balancing the model at 25% of the chord (1/4th back of the total
distance of the front to back distance of the airfoil) will ensure that your
model will be much easier to fly for virtually any kind of airfoil shape
that you will encounter these days.

The last statement absolutely, positively works and it will make your model
much easier to fly and to maintain control of at all times. Models that are
tailheavy when compared to the preceding recommendation will tend to drop
their tails in turns, will be a PITA to land in any kind of wind and will
retard the learning process for new student pilots.
