I can tell you what I did with mine but I would get your feet wet again before you want to bore holes in the sky a bit faster.
I have a bigger engine on mine.
I allso reworked the root of the wings so when I butt them together I have very little dihedral and I took the big fat nose wheel off and converted the plane into a tail dragger.
The nose wheel turns with the rudder and caused to much drag.
I also set all the control surfaces to MAX for better response.
Hope this helps some and I would go with the metal type snap links.
I have them on all 3 of my planes.
