2 questions on Posky 747v3

Hi all I have been flying around with the the great Posky747v3 and while it flies great there are 2 problems that I have noticed 1)the spoliers do not deploy automatically on landing- and yes I have them armed before and 2) get this bird to stop in a more realistic landing distance cause right now the thing stops in no time flat even at near max landing weights. I am using the PSS panel if that makes a difference but i could sure use some tips on how to solve these two problems because I love this bird!!
