Above is the sail servo bracket with the hole marked that needs to be cut out to insert the sail servo. I cut this using the Dremel with the cut off wheel installed.
Below are 2 shots of the bracket with the sail servo dry fitted to it.
These next 2 photos show the sail servo bracket dry fitted to the hull with the sail arm attached. It is necessary to dry fit this to make sure the sail arm has the room to travel the proper arc without having any obstructions.
