I always seem to have a problem mounting servos in Balsa planes, often the gap to get them in is that tiny bit too small and you have to enlarge it by a millimetre or two.
I then find when I go to screw them down the screw's right on the edge of the hole and has nothing solid to screw into, does anybody else get this and any bright idea's of what to do, should I just CA them instead ??
