Taven, The owner of bladecx2.com(Extreme's manufacturer) Told me that the grips/blades are for spare parts for the whole core system. They weren't intended to be used with e-flight's assembly.
You can still try and if you get it all working together then let me know what I missed.
the system is made to work together EXTREME CORE part SL50
if you have only SL52 it can still work but it is folding blade only
sold many all clients happy
most of the comon problem normaly is very simple
blades not tight or inverted number 2 is supose to be upper not lower, flybar is to stiff
those thing are easy to fix
real support on those link
