Hi Matt,

great stuff! You're giving me lots of ideas. I should have my viper within a few weeks

Looking at the close-up of the rudder/fuse, and the space between them, would it be possible to add another (phenolic or PCB material) hinge just below the fin, but in the rudder?

That would make removing the rudder a non-issue. 2mm material would be enough I think.
