What size motor do you have on your Estarter?
The Gws 400 sized one(cant remember exact name right now)
Have you glued the two fuse halves together already?
Yes
Have you glued those little squarish plastic pieces to the front of fuse in the little indentations (after cleaning them and scuffing the back of them with sandpaper)?
Dont remember seeing anything like this in the manual, unless you mean the ones that hold front part of wings down(one goes on first, then the other one goes ontop of it with 3 cleats sticking out to help support the wing I assume)
Have you trimmed the cowl yet as per the instructions?
Yep
