One thing non of you guys mention is you need to replace the trim
springs on the all flying tail models.

a buddy at minden did that on his Nimbus 2.
By replacing the 70's vintage worn out stretched trim springs with new
one it changed the glider.
He could let go of the stick and it would not go divergent on him for
extended periods.

Anyone buying of flying an all flying tail Schemp anything should
replace the trim springs.
