Indeed. The other models (including the base G115, A, B, etc as generally horrible as they are) use a different construction of control surface, in particular around the bracket mounts. The different construction doesn't require that nuts are torqued (iaw the manual) to an extent that may, on odd occasions, pull the bolt head through the surface...
