You probably should use something thicker than an exacto, as well - I
found the smallest screwdriver in a micro set was just right - the line
needs to be thick enough that the epoxy doesn't meet when the the
ailerons are flexed.
I have a broken hacksaw blade I use for "digging" out the slot of epoxy . I ground the broken end off smooth to allow the teeth to meet the slot. Bill G.
