Cantilever sail arm

When my head hit the pillow last night and my imagination kicked into the usual modelling hyper drive a cantilevered sail control arm flashed into my minds eye.  All of a sudden I could see how a normal length servo arm might provide enough sheet travel for my latest Rebel RG65 project.

This evening I set about knocking up a crude experiment just to see if my idea had any legs and I was quite impressed.  A normal servo arm radius of 25mm provided 100mm of sheet travel.  Another advantage is the torque isn't jeopardised and it's also relatively light.  All together a win, win idea perhaps.
