>>> A few things that jumped out that need trimming...

>>> The balance seems fine at 8" from the leading edge at the root.

>>> It seems to have a bit to much right thrust with the 16.5 x 12 2 blade

>>> In knife edge going right with the canopy facing me it pushes a bit to

>>> pulls just a little to the canopy.
>>>
>>> I will start working my way through the trimming guide next time out.

>>> Thanks again for everyones help!
