Hi. I'm building a World Models Aure and have come up against a bit of a problem...

After having had some difficulty installing the aileron servos I looked at the next step in the instruction manual, i.e., attaching the rudder to the fin. I was looking forward to a simple step which I expected to knock over in 5-10 minutes. You can imagine my dismay as I pulled out the fibreglass fuse to find that the hinge slots had not been cut in the fin. The nylon hinge strips were preinstalled in the rudder.

How do I go about cutting (good) hinge slots in fibreglass and what tools do I need?

Thanks in advance for your advice
